The above summary and the following examples are intended to be illustrative of the invention and the embodiments of the invention. [Embodiment] 7/15 201138280 Please refer to the second figure 'The power conversion system with zero voltage starting for the present invention, including the - power conversion circuit 2〇7, the zero voltage detection module 2〇9, the storage capacitor 2U, - power storage switch unit 213 and a bridge rectifier 217. In higher load applications, the power conversion system may further include a power factor correction unit 203 and a small capacitance 219. The power storage switch unit 213 and the zero voltage detection module 2〇9 are the zero voltage starting devices of the present invention. ^ After the power conversion system is connected to the power supply and receives the input voltage vh, the small-capacity capacitor 219 is first charged 'after the power factor correction unit 203 and the livestock capacitor 211 are charged' to supply the power conversion circuit 2〇7 Operation. In general, the power supply is an AC power source, and the input voltage Vin (assumed to be a Sin wave) in the voltage 苴 is the point where the positive amplitude and the negative amplitude are the largest at the phase angles of 9 和 and 27 分别, respectively, and the twist (36) Twist) and 180 degrees are zero voltage points.夂 At the moment when the input voltage Vin is connected, the phase of the input voltage νώ may be any point from G to 360 degrees, and it is impossible to control whether the input between the power supply white is at a high voltage or a low voltage. If it is at a high voltage, there will be a large inmsh current that instantaneously enters the power conversion system. Therefore, it is necessary to have a mechanism for removing the dog current, so that the circuit of the system is damaged due to the surge current. . ~ 'In order to maintain the line stability', the zero voltage detecting module 209 and the power storage switch unit 213 are provided for the smashing & The power storage switch unit 213 is connected in series to the storage capacitor 211, and the zero voltage 4 detection module 209 is connected to the input AC voltage vin and the power storage switch unit 213, and the input voltage Vin is converted into the detection signal 8 plus, and ^ The control signal sccn of the power storage switch unit 213 is controlled. 8/15 201138280 The zero voltage detection module 209 can include a rectifying unit 2091 and a zero voltage detecting unit 2093. The rectifying unit 2091 receives the input AC voltage Vin and performs rectification to generate a detecting signal Sdet according to the detecting signal. Sdet, the zero voltage detecting unit 2093 can determine whether the input AC voltage Vin is at a potential of zero voltage. If the control signal Scon is generated to turn on the power storage switch unit 213. That is to say, in the power conversion system of the present invention, since the power storage switch unit 2 is still turned off, the input voltage Vin does not immediately pass through the path pair of the bridge rectifier 217 and the diode D]. Capacitor 211 charging 'will pass the zero voltage detection mode, group 2〇9 judgment, when the input voltage Vin is indeed at zero voltage (in this embodiment, the phase angle of the Sin wave is 0 degrees, 180 degrees and 360 degrees). When the power storage switch is turned on for a few 213 ', the input voltage Vin starts to charge the storage capacitor, and this will ensure that the storage capacitor 211 and the power conversion unit 2〇7 are only received, because of the above mechanism. When the power conversion system is started when ::H1 is zero voltage, there is no problem of circuit damage. Referring to the second picture, the power conversion — and the standby circuit have been 3 thin and early, and a mine M + ', D vine has been smashed to include a fuse 215. The electromagnetic interference suppression unit 2〇1 is used to protect the power of the power conversion system through the standby circuit when the storage capacitor 211 + $% (not shown) has not been shrunk by the power conversion unit to generate a standby operation. In standby mode. Instead, the supply to the load 'allows the load to be transferred 203 for boosting,' turns on the power factor correction. The single-sided over-power conversion unit 207 provides the output 9/15 201138280 voltage Vout to the load for proper operation. Referring to the third figure, a circuit diagram of an embodiment of the zero voltage detecting module 2〇9 of the present invention includes a rectifying unit 2091 and a zero voltage debt detecting unit 2093. The zero voltage detecting unit 2〇93 may further include a voltage dividing unit 301, a first switching unit 303, and a second switching unit 3〇5. The second switching unit is a silicon-controlled rectifier (SCR) whose characteristic is that when the gate receives a high voltage, the anode and the cathode (cath〇de) The current can flow, and the gate becomes low voltage after the conduction, and the anode and the cathode are not worn. Only when the current flowing between the V pole and the fe pole is less than a current, the rectifier rectifier is turned off. The s-ary rectifying unit 2091 rectifies the input AC voltage % and transmits the voltage through the voltage dividing unit to generate a signal si Γ: switch το 3 () 3 is switched to the shrimp unit 3G1, receiving The detection signal Sdet is switched between on or off state. When the f signal sdet (the input voltage Vin is full-wave rectified and divided) is two levels (representing the input voltage at this time is also a high standard) The first switch unit 303 is turned on, so that the auxiliary control signal s_ is grounded, and the second switch unit 3G5 is kept off. Therefore, the control signal ScGn output to the power storage switch unit 213 is at a low level, and the power is not turned on. Switch unit 213. When the detection signal S d et domain level (that is, represents the current round = low level), the first switching unit 3 〇 3 is cut off, so that the auxiliary control - tiger saux is pulled to the level by vcc, let the first The second switching unit 3〇5 is turned on by the high-level auxiliary control signal Saux, so that the control signal Sc〇n of the output electrical switching unit 213 is also raised by vcc to the Micro Motion 10/15 201138280 bit, further enabling the power storage switch The unit 213 is turned on to activate the overall power conversion system. In this way, the power conversion system can be started at a low level to avoid damage to the power conversion system caused by excessive surge current. Yes, because the second switching unit 305 is a rock-controlled rectifier (SCR)', after the conduction is turned on, the second switching unit 3〇5 does not return to the off state even if the auxiliary control signal is lowered to the low level. The invention realizes the zero voltage turning mechanism, the power conversion system does not need the generation of the surge current, and does not contradict the early element, and can also prevent the high, and does not cause the setting of the spur suppression system; In other words, To make electricity, ^7" to reduce the additional power consumption of the input power, efficiency and stability, '', conversion system circuit simplification, set the scope of this [simplified description] for the conventional power supply system BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram of an example of a zero voltage turn-on, and an example of a dynamic power conversion system.
