(4) The controllable rhyme group enables the single-phase motor to stop rotating or re-rotate, and at the same time, by controlling the single-phase motor to rotate to the pole commutation region, a plurality of driving voltage pulses are continuously provided to prevent the driving current from generating a whole segment in the commutation region. The state of zero current. ^ [Prior Art]

First, please refer to FIG. 8A and FIG. 8B, which are schematic diagrams of a single-phase motor driving device and a driving signal thereof in the prior art, wherein FIG. 8A is a schematic diagram of a single-phase motor driving circuit of the prior art, and 8B is a schematic diagram of a driving waveform (or driving signal) of a single-phase motor driving circuit corresponding to FIG. 8A.

As shown in FIG. 8A, the first driving electro-crystal system is composed of an NPN-type bipolar transistor 2 and an NPN-type bipolar transistor 4, and drives the first driving power by driving signal A and driving signal D. Crystal. When the driving signal A and the driving signal D are both high, the NPN type bipolar transistor 2 and the NPN ❹ type bipolar transistor 4 are both turned ON, and the driving current flows from the power source VCC through the NPN type. The bipolar transistor 艏 2' then passes through the inductor 6 and the NPN-type bipolar transistor 4, and finally to the ground potential VSS. At this time, the inductor coil 6 will form a closed magnetic field in the direction of the paper exit surface according to the ampere right hand rule. When the driving signal B and the driving signal C are both at a high potential, the NPN-type bipolar transistor 8 and the NPN-type bipolar transistor, that is, the second driving transistor are all turned on; similarly, the driving current is from the power source. The VCC flows through the NPN-type bipolar transistor 8, and then passes through the inductor 6 and the NPN-type bipolar transistor 10, and finally to the ground potential VSS. Obviously, the inductor 6 201029308 will also form a closed magnetic field in the direction of the paper feed surface according to Ampere's right hand rule. The single-phase motor is rotated by appropriately improving the direction of the drive current of the inductor 6. In addition, as shown in FIG. 8B, when both the driving signal A and the driving signal D are at a high potential, both the driving signal B and the driving signal C are kept at a low potential; therefore, when the first driving transistor is turned on (ON), The second driving transistor is not turned on (OFF); when the driving signal B and the driving signal C are both high, the driving signal A and the driving signal D are both kept at a low potential; therefore, when the second driving transistor is turned on ( When ON), the first driving transistor is not turned (OFF). Obviously, the first driving transistor and the second driving transistor can be controlled to be turned ON or OFF independently via the driving signal of the 8B picture. However, during the operation of the implemented circuit, the driving signals A, B, C, and D will produce offset changes, so that the NPN type bipolar transistors 2, 4 and the NPN type bipolar transistors 8, 10 are in progress. Complementary turn-on (ON) or non-conduction (OFF) may cause transient simultaneous conduction of the NPN-type bipolar transistor 2, 10 or the NPN-type bipolar transistor 8, 4. At this time, the drive current passing through the inductor 6 has an oblique current ineffectively causing the torque to be generated, so that the direction of the drive current of the inductor 6 is sharply changed, as shown in Fig. 8B. This phenomenon of a sudden change in the direction of the drive current causes problems such as vibration, noise, and power consumption of the single-phase motor. In order to solve the problem of FIG. 8B, the US Patent No. 7,009,351 proposes a method of turning off the driving current during commutation, as shown in FIG. 9A, FIG. 9B and FIG. 9C, wherein FIG. 9A is a prior art single. FIG. 9B is a schematic diagram of driving signals of the anti-lock protection circuit 122 corresponding to FIG. 9A; and FIG. 9C is a schematic diagram of driving signals of the single-phase motor driving circuit corresponding to FIG. 9A. As shown in FIG. 9A, the anti-lock protection circuit 122 is composed of a capacitor 124, a constant current 5 201029308, a source 126, and an NPN type, such as a transistor i2, a voltage VREF, which is mainly used to rotate and stop. State. The anti-locking material detects that the single-phase motor is in the flow source to form the charging circuit and the capacitor 124 is the discharge circuit, and on the non-ground side of the capacitor 124 = voltage circuit (10) + (non-inverting input and reference voltage Ο When the connection is made and the (inverted input) terminal is connected to the non-ground side of the capacitor 124,

The circuit 130 can turn the "H" signal to the control circuit 132 by comparing the charge and discharge voltage of the non-ground side of the capacitor 124 with the magnitude of the reference voltage VREF to indicate that the single-phase motor is in a rotating state; When the signal is sent to the control circuit 132, it means that the single-phase motor is in the stop state, and the operation process of the anti-lock protection circuit 1S2 is as shown in Fig. 9B. When the anti-lock protection circuit 122 sends the signal of the single-phase motor rotation to the control After the circuit 132, the control circuit 132 then provides a plurality of driving signals (for example, Al, B1, C1, and D1) to complementarily drive the first driving transistor and the second driving transistor, by appropriately changing the inductance coil 1〇. The driving current direction of 6 causes the single-phase motor to continue to rotate, wherein the first driving transistor is composed of the NPN-type bipolar transistor 102 and the bipolar transistor 104, and the second driving transistor is composed of the NPN 蜇 bipolar transistor. 1〇8 and NPN type bipolar transistor 110. Then, the driving signals A2, B2, C2, and D2' are driven and output via the absolute value circuit 120 to make the direction of the driving current applied to the inductor 1〇6. Switch The fixed period before the point "controls the timing of the first drive transistor and the second drive transistor (ON) or non-conduction (〇FF), so that the drive current of the inductor 106 is regenerated. By this single-phase motor The drive device, the direction of the drive current of the inductor 106 will change slowly (SOFT SWITCHINGE action), such as the drive current of the thick black line of the 9C: _. Thus, the vibration of the single-phase 6 201029308 motor can be suppressed 'noise and power consumption Big problem. However, when the single-phase motor is in the rotating state, the driving current of the single-phase motor is rapidly turned off due to the drive circuit, causing the current to be unsmooth, and it is possible to generate a whole zero current near the commutation point. As shown in the drive current diagram in Figure 9C, it will obviously cause the single-phase motor to suddenly lose its driving ability near the commutation point. It can only use the residual inertia to cross the magnetic pole commutation area, which is easy to cause the single-phase motor speed to be unstable. Disadvantages.

However, the control signal for driving the single-phase motor driving device to generate the driving current of the present invention is the same as that shown in FIG. 8B and FIG. 9B, and therefore is not fully described in the following description; The single-phase motor mentioned is the same as that of the prior art, so the detailed structure of the single-phase motor is not shown in the figure. Moreover, the drawings in the following texts are not completely drawn according to the actual relevant dimensions, and their functions are only to express the schematic diagrams related to the _^ creation features. First, please refer to FIG. 1A and FIG. 1B, which are schematic diagrams of circuit blocks of the single-phase motor drive of the present invention. As shown in FIG. 1A, the single-phase motor driving device of the present invention includes a Hall element 10, a comparison circuit 20, a commutation point sampling circuit 30, a smoothing coefficient adjustment circuit 40, a triangular wave oscillation circuit 60, a PMW control circuit 70, and an output. Stage control circuit 80 and output stage circuit 90, etc., wherein commutation point sampling circuit 30 is composed of complementary bias comparison circuit 31 (composed of comparison circuit 31A and comparison circuit 31B) and sampling logic circuit 32 (by a latch circuit) 35 and a switching element 34 are combined; and the output stage circuit 90 is composed of a first driving transistor pair (91, 94) and a second driving transistor pair (92, 93) and an induction coil 95, And electrically connected to the first driving transistor pair and the second driving transistor, as shown in FIG. 1B. Next, in order to explain in detail the operation of the single-phase motor 12 201029308 driving device when the single-phase motor of the present invention is rotated, please refer to FIG. 2A, FIG. 2B and FIG. 3 together. Referring to FIG. 2B first, the Hall element 10 is disposed at a rotational position of a single-phase motor (not shown). For example, the Hall element 10 is disposed on one side of the rotor for outputting a positive The sine wave signal (H+) and the reverse sine wave signal (H-), wherein the intersection of the forward sine wave signal and a reverse sine wave signal is called a phase changing point. Then, the sine wave signal converts the sine wave signal into square wave signals 2〇1 and 2〇2 via the comparison circuit 20 to determine the position of the single-phase motor; obviously, the square wave signals 201 and 202 are opposite. At the commutation point of the sine wave, there will be a corresponding commutation point. In addition, in addition to providing a sinusoidal signal, the Hall element 1 can also provide the rotational speed of the single-phase motor and provide information for determining the position of the single-phase motor. At the same time, the 'square wave signals 201 and 202 are also transmitted to the commutation point sampling circuit 30' and electrically connected to the input terminals of the pair of comparison circuits 31A and 31B disposed in the commutation point sampling circuit 3A, and The comparison result of the comparison circuits 31A and 31B passes through the latch circuit 35 in the sampling logic circuit 32 to generate a commutation signal 33 (OSL), and then the switching element 34 is driven by the commutation signal 33. Finally, the output terminal 73 A commutation smoothing voltage (vmIN) signal is output. The generation of the commutation smoothing voltage (VMIN) is related to the speed of the single-phase motor and the magnitude of the drive current. 'Under ideal conditions, the switching point of the single-phase motor pole will happen to be the switching point of the induction coil current reversal, as shown in Fig. 3. Shown. In particular, the aforementioned commutation signal is determined by the voltage difference between the input positive sine wave signal (H+) and a reverse sine wave signal (H-) being less than a certain voltage VOS (Voltage Off-Set). Used to generate a pulse wave with a time width of TOS (Time Off-Set). For example, when the time width of the TOS pulse wave is l〇us, the voltage difference between the positive sine wave signal (H+) and the reverse sine wave signal (H·) is less than a certain voltage v〇S. Come out; 13 201029308 For example: When setting VOS in lmv~10mv, the time width of TOS pulse can be obtained as lus~100us. In addition, the purpose of defining the time width of the TOS pulse wave is to define the range of the commutation interval when the single-phase horse is rotated. Under normal conditions, the commutation smoothing voltage (VMIN) is output at a low level, but when When the motor pole is in the commutation interval, the commutation smoothing voltage (VMIN) is converted to a higher level so that the triangular wave can be cut to generate a modulated PWM voltage output (also known as PWM) in this range. The signal; for example, the modulated PWM signal); so that the range of the commutation interval can still provide a plurality of instantaneous driving signals, so the driving current can still be maintained on the induction coil 95 in the commutation interval. To prevent the drive current from generating a full zero current near the commutation point. Referring to FIG. 1A again, when the output of the commutation point sampling circuit 30 has output a commutation smoothing voltage (VMIN) signal to the input sigma 73 of the PWM control circuit 70, the triangular wave generated by the triangular wave oscillating circuit 60 is also output to After the input terminal 72 of the control circuit 70 and the reference voltage Vth are also input to the input terminal 74 of the PWNi control circuit 70, the PWM signal can be generated in the PWM control circuit 70 by cutting the voltage of the triangular wave, and the PWM signal can be The output 71 of the PWM control circuit 70 is output. It is particularly emphasized here that when the motor pole is in the commutation interval, the commutation smoothing voltage (VMIN) is converted to a higher level in the time width range of the TOS pulse, so that it is converted to a higher position. The commutative smoothing voltage (VMIN) can cut the triangular wave to produce a modulated PWM signal. In other words, when the motor magnetic pole has not reached the commutation interval, it will generate the PWM signal ' from the reference voltage Vth and the triangular wave', and when the motor magnetic pole enters the commutation interval, it will be converted into a higher level of the commutation smoothing voltage (VMIN). ) The triangle wave can be cut to produce a modulated PWM signal. Therefore, 'there can still provide a plurality of PWM signals of the modulation 201029308 in the range of the commutation interval, so the driving current can be maintained on the induction coil 95 in the commutation interval to prevent the driving current from being commutated. A state of zero current is generated near the point to eliminate the current surge generated by the motor during the phase commutation of the magnetic pole, achieving the purpose of smooth switching of the single-phase motor drive current, making the single-phase motor smooth and quiet - and efficient The way to turn. Since the generation of the commutation smoothing voltage (VMIN) is related to the motor rotation speed and the magnitude of the driving current, for example, when the motor rotation speed is slow, the width of the TOS is gradually widened, so that the zero current time of the motor in the commutation interval becomes It is easy to make a motor that is unstable during commutation. In order to solve this phenomenon, the present invention can further configure a smoothing coefficient adjusting circuit 40 in the commutation point sampling circuit 30, so that the output end 41 of the smoothing coefficient adjusting circuit 40 is electrically connected to the input end of the sampling and logic circuit 32. Among them, the smoothing coefficient adjustment circuit 40. The most important function is to adjust the width of the TOS. Therefore, when the motor rotation speed is slowed down, the smoothing coefficient adjustment circuit 40 can provide a conversion coefficient β when the motor rotation speed is slowed down to maintain the TOS width at a fixed value, so that the motor does not generate during commutation. A zero current to achieve the best current smoothing effect. Next, please refer to the first and fourth diagrams at the same time. The fourth diagram is the waveform diagram of each node of the first capsule. As shown in Figure 1, the single-phase motor rotates.

During the process, the square wave signals 201 and 202 are sent to the input end of the output stage control circuit 80; wherein the driving signals provided by the output stage control circuit 80 are Η 2, L1 and L2 and the 第 第 in the 9th drawing The driving signals of C1 and D1 are the same, and the driving signals HI, H2, L1 and L2 are electrically connected to the opposite NPN type bipolar transistors on the output stage circuit 90. Therefore, the first driving transistor pair (including the NPN-type bipolar transistor 91 and the NPN-type bipolar transistor 94) of the output stage circuit 90 is electrically connected to the induction coil 95 to provide a rightward direction of the induction coil 95. Driving current; and the second driving transistor pair (including NPN 15 201029308 ^bipolar transistor 92 and NPN bipolar transistor 93) is electrically connected to the induction coil 'and provides the induction coil 95 - and the left direction The drive current thus complements the first drive transistor pair and the second drive transistor pair on the wheel-out stage circuit 90.

Next, referring to FIG. 4A, when the PWM control circuit 70 sends the commutation smoothing voltage (VMIN) to the input terminal of the output stage control circuit 8〇, it selects the driving signal (ie, H2, L1). And L2) to perform modulation, for example: When the induction coil 95 needs a faster discharge time, the drive signals Η1 and Η2 can be modulated sequentially, as shown in Fig. 4, wherein the black solid line is actual. The driving current is driven, and the dotted line and the diagonal line are the ineffective currents that can be saved. In addition, when the induction coil 95 needs to have a long discharge time, it can also drive only the first half of the TOS and the commutation point interval, that is, drive the first half of the signals Η1 and Η2, respectively. The waveform diagram of each node in the figure, as shown in Fig. 4, where the black solid line is the actual driving current, and the dotted line and the diagonal line part are the ineffective currents that can be saved. On the contrary, it can be driven only to the second half of the commutation point interval to drive the second half of the signals H1 and Η2 respectively. At this time, the waveform diagram of each node of the first diagram is as shown in FIG. 4C, in which the black solid line For the actual drive current', the dotted line and the slash part can save: effective current. Obviously, the present invention can determine the number of the most ==, (_) and the voltage width by adjusting the triangular wave period of the triangular wave seismic circuit 6 and the conversion coefficient β of the smoothing coefficient adjusting circuit 4G, so that the change can still be made here. A plurality of instantaneous drive currents are provided to achieve a state of zero current. Prevent driving near the L phase

An even pole arm; and a rotor that cooperates with the stator; then, a Hall element is disposed on one side of the rotor and electrically connected to a comparator 2 . Next, the day piece of the power month b having the single-phase motor driving device of the present invention is connected to the Hall element 10 and the comparator 2A, so that the single-phase motor can be in the range of the commutation interval, and still A plurality of instantaneous drive currents are provided to achieve an optimum current smoothing effect to prevent the drive current from generating a full zero current near the commutation point. In addition, in the process of manufacturing the single-phase motor driving device of the present invention, it is possible to selectively form the induction coil 95 in the integrated circuit; however, it is also possible to selectively arrange the induction coil 95. In addition to the integrated circuit, in this case, the integrated circuit needs to be further electrically connected to the induction coil 95; the above are all embodiments of the present invention. In accordance with the above description, the present invention further provides a method of driving a single phase motor. First, a Hall element 10 is provided for outputting a forward sine wave signal (H+) and a reverse sine wave signal (H_)' and the forward sine wave signal and the reverse sine wave signal form a commutation Then, a comparison circuit 20 is provided. The comparison circuit 20 is electrically connected to the output end of the Hall element 10 for converting the forward sine wave signal and the reverse sine wave signal generated by the Hall element 10 into a square. Wave signals 201 and 202; then, a phase switching point sampling circuit 3 is provided, and the phase switching point sampling circuit 30 is connected with a forward sine wave signal (H+) and a reverse sine wave signal (η-) to generate a The commutation signal (OSL) is used to define a pulse signal of a commutation interval, and an output phase 73 of the commutation point sampling circuit 30 outputs a commutation smoothing voltage (VMIN) signal. It should be emphasized here that the commutation signal 33 (OSL) is determined by the voltage difference between the input positive sine wave signal (H+) and the reverse sine wave signal 17 201029308 • number (H-) is less than a certain voltage VOS. (VoltageOff-Set) is defined to 'generate a specific time width TOS (Time Off-Set). In addition, the purpose of defining this particular time width TOS is to define the range of commutation intervals when the single phase motor is rotated. Under normal conditions, the commutation smoothing voltage (VMIN) is a low level output, but when the motor pole is in the commutation interval, the commutation smoothing voltage (VMIN) is converted to a higher level so that the triangular wave can be cut. Used to generate a modulated PWM voltage output (also known as a PWM signal) in this range. φ. Next, a PWM control circuit 70 is provided.

Obviously, when the forward sine wave signal (H+) and the reverse sine wave signal (H-) enter the commutation interval, the commutation smoothing voltage (VMIN) signal changes state to a higher level, so that The triangular wave can be cut in the commutation interval such that at least one control signal generates a plurality of modulated PWM voltages in the commutation interval. By using a plurality of modulated PWM voltages in the commutation interval, a plurality of instantaneous driving signals can still be provided in the range of the commutation interval, so that the induction coil 95 in the commutation interval remains A drive current can be maintained to prevent the drive current from producing a full zero current near the commutation point.
