Specific implementation mode
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment
The present invention provides a kind of Multi-path synchronous trigger circuit of the negatively charged pressure biasing of Magnetic isolation type, and technical solution is as follows：
First central control portion generate analog signal, the Mai Kuan ﹑ phases and frequency of the drive signal that can be controlled,
The break-make of switching tube in its signal exported control inverter circuit, switching tube can select MOSFET and IGBT etc., to raw
At bipolar voltage waveform, load end is penetrated through connecting line is used as primary side in the magnetic core hole of ferromagnetic isolation part, to reach
Multiple transformers are total to the purpose of primary side.
Hereafter, since series connection penetrates multistage magnetic core, with partial pressure effect, so boosting may be used in Magnetic isolation transformer
Pattern improves secondary side output signal voltage amplitude.
The input terminal of drive control module after isolation, input amplitude will meet the driving voltage of semiconductor switch pipe,
Positive-negative polarity is different according to the selection of the model of switching tube.When input signal is via two metal semiconductor oxide field-effect pipe structures
At driving circuit after, cardinal principle is to constitute an equivalent integrating circuit, so there is maintenance voltage, and
The voltage exported afterwards will go first through differential circuit, then trigger bipolar junction transistor by delay trigger circuit, can be by master
Switch short in circuit, makes it cannot get driving voltage, plays the purpose of delay driving, specific delay time and differential electricity
The parameter on road is chosen related.
When controlling semiconductor switch pipe, due to the coefficient of coup, between the positive potential and negative potential of half bridge signal,
Not plus the switching tube of delay circuit will take the lead in being connected, after dead time caused by delay circuit, corresponding switching tube
By Delayed conducting, to generate the multiple signals of different sequential.
Fig. 1 is the whole schematic diagram of the present invention, as shown in Figure 1, the present invention includes by the center of analog signal module composition
1 ﹑ inverter circuits of control section, 2 ﹑ Magnetic isolations part 3 ﹑ drive control modules, 4 ﹑ semiconductor switch, 5 component part.

Diode makes M2 be connected, then the differential circuit 15 by being made of C1 and R1, and Q1 is made to be connected, at this time partly leading Marx generators
By Q1 short circuits, no open signal, switching tube continues to be held off 5 gate pole of body switch, until delay time that R1C1 is determined it
Afterwards, Q1 is turned off, and semiconductor switch gate pole is charged to positive voltage, hence into conducting state.After open signal disappears, M2 is therewith
Shutdown, the charge on gate capacitance does not have release channel at this time, to the conducting state before maintaining.Similarly, when shutdown is believed
Number arrive, so that M1 is connected via the parasitic diode of M2, Marx generator semiconductor switch gate voltages be it is negative, acquisition negative bias
Pressure, to make its reliable turn-off.But due to diode equivalent BJT, the charge on gate capacitance is made to be released channel, born
