The secondary side drive coil Ti3 is coupled to the drive circuit 32 for driving the slave power circuit. The slave power loop includes a forward rectifier 311, a flywheel rectifier 312, and a storage inductor ^. = connected to the second end of the rectifier 311 to the secondary side rear regulator & the first end of the forward rectifier 311 and the plate wheel rectifier 312 are connected to the connection point &, the connection point & and the auxiliary voltage output The storage inductor L5 is connected in series between the terminals. The second end of the flywheel rectifier 312 is connected to the second end of the secondary side power coil τ 并 and is connected to the ground end. The control end of the flywheel rectifier 312 is connected to the control of the flywheel rectifier of the main output circuit, and is subjected to its voltage signal. , the device & is connected to a switch controller 33.交门登古口口一1: The road 32 is connected to the secondary side drive coil Tis and the control terminal of the forward rectification benefit 311 of the subordinate power circuit for providing the voltage signal of the forward rectifier 3 ι control terminal, and the two-person The second end of the side drive coil T13 is connected to the second end of the forward rectifier 3ι.实 A circuit diagram is implemented for one of the first diagram embodiments. Using the crystal ground, rectifying (four) surface sound _ Na as the __32 d7 and - interlocking switching circuit, the moving coil T Wei forward transistor M7 gate. The interlocking switching circuit includes a transistor Q1, a PNP for an islam, a bipolar V training bipolar transistor q2, and two electric mR1 and R2. The transistor is connected to the emitter of the electric crystal Q2, and the junction is connected to the gate of the forward transistor M7. The bases of the two transistors Qi and Q2 are connected, the connection point of the base is connected to the collectors of the transistors Q and q2, and the resistors Ri and R2 are respectively connected. The collectors of the transistors Q and Q2 are respectively connected to the cathode of the diode - D7 and the second end of the secondary side drive coil T13, and the anode of the diode d7 is connected to the first end of the secondary side drive coil T13. ^ When the voltage of the first terminal of the secondary side drive coil τ13 is vs2 (positive value), the transistor Q! is turned on and the transistor Q2 is turned off to turn on the forward transistor My. When the voltage of the first terminal of the secondary side drive coil is ·ν^(negative value) or 0, the transistor Q! is turned off and the transistor Q2 is turned on so that the forward transistor is turned off. Because the gate-source voltage wave of the forward transistor m7 is non-negative, this driving mode is called unipolar driving mode. FIG. 12 is another example of the embodiment of FIG. The difference between the implementation circuit diagram and the embodiment shown in FIG. 5 is that the bipolar driving mode (bip〇iar diving 1T10(ie) is used. As shown, the driving circuit 32 only includes the two connected resistors, R2, and then respectively Connected to the first end and the second end of the secondary side driving coil 。η. The connection point of the resistors I and r2 is connected to the gate of the forward transistor, and the resistor R2 is connected to the gate and source of the forward transistor Μ? When the first terminal voltage of the secondary side drive coil τη is Vs2 (positive value), the partial pressure of the resistors Ri and φ R2 is positive, and the forward transistor Μ7 is thus turned on. When the secondary side drive coil T13 When the voltage at the ^ terminal is -Vs2 (negative value) or 0, the partial pressure of R and R2 is nonpositive, and the forward transistor is closed. When the secondary side rear adjuster S2 is a controlled switch When the gate of the forward transistor M? of the slave power circuit can be connected to the gate of the forward transistor of the main output circuit, The drive circuit 32 is omitted by the voltage signal, and the circuit is further simplified. Further, the forward transistor μ is moved to the second end of the tertiary power coil 14 and the common source of the flywheel transistor Architecture. Also, the axis of the subordinate power circuit - connected to the ground end of the second _ of the hybrid Mil, the first end is connected to the secondary side 旣 _ Τ ι and the secondary ender adjuster & _ _ end , 12 .M334571 The two control terminals are respectively subjected to the voltage of the power terminal of the main wheel circuit, and the remaining circuits are as in the foregoing embodiment (4) the rectification 11 and the recording rectifier control 11 the first green circle Τ 13 , the forward transistor Μ Pressing the fine pressure waveform), the main wheel output circuit of this embodiment::==electric value)::=: subject: =τ; the first end of the electric *" (positive a mountain + i open, flywheel transistor The gate of M8 is successively received, and is closed by the closed-circuit electric calendar signal (voltage 0) of the flywheel transistor in the circuit. On the secondary side, the shielding effect of the regulator s2 on the leading edge of the voltage waveform of the secondary side power coil Tl4 is as follows. The shaded area in Fig. 13 is shown. Since the shadow _ G < t < w is closed due to the secondary side rear adjuster S2, there is no current The warp beam M7 even if it has been turned sideways. The continuous current of the energy storage thief L5 chases the body diode of the f-wheel transistor Ms to conduct and discharges electric energy through the furnace and the wave capacitor Q. During the non-concealing period, Dingling<t<Ton, because the secondary side rear adjuster S2 is turned on, the forward transistor starts to conduct current, and the continuous current of the energy storage «L5 is commutated from the body diode of the flywheel transistor Ms to the forward transistor M? The forward transistor Μ?, the secondary side rear adjuster core, the secondary side power coil T14, and the filter capacitor C5 store electrical energy. During the reset period (10) < 丨 < T(10) + 7; ^/, the first terminal voltage of the primary side drive coil T 〗 3 is _VS2 (negative value). The gate voltage of the forward transistor M7 is turned off by 〇 (unipolar drive) or negative (bipolar drive). The gate of the flywheel transistor Ms is turned on by the gate voltage Vs of the flywheel transistor in the main wheel circuit. The energy storage inductor L5 discharges electric energy via the flywheel transistor ^8 and the ferroelectric 0^^. During the delay period of the heart 5 匕 + S K C, * the cross-voltage of the two-side drive coil T!3 is 〇, and the gate voltage of the forward transistor M? is turned off. The gate of the flywheel transistor Μδ is closed by the gate voltage 0 of the flywheel transistor Μ2 in the main wheel output circuit. The energy storage inductor Ls discharges electric energy via the body diode of the flywheel body 1 and the filter capacitor C5. Figure 14 is a one-week period. The embodiment shown in Figure 11 is the first end of the secondary side drive coil Τπ of the slave output, the forward transistor Μ; and the gate of the flywheel transistor (control terminal) 13 .M334571 Voltage timing (voltage waveform) diagram, the main transmission (four) road system of this embodiment is an example of the eighth diagram.
