Specifically, in above-mentioned preferred embodiment, switching switch S1 switchs for a high-frequency drive, switching switch S1 works
Operation mode is：The dutycycle switch working state that first continues for some time, one end time is remained open again.Such as：The switching is opened
S1 is closed in the duty cycle state continuous firing 6ms opened with 10 μ s, 5 μ s are closed, then remains off 14ms again, then with it
Preceding duty cycle of switching works the working time as before, then keeps the off-state of duration as before again, such as
This is reciprocal, going round and beginning again to be operated.Because follow-up explanation is all based on what the work schedule was operated, for convenience
Illustrate, the off-state of a length of 14ms when keeping is referred to as long off-state.
Specifically, in above-mentioned preferred embodiment, the transformer TF first coil number of turn and the number of turn of the second coil it
Than for 3:1.
Preferably, in above-mentioned preferred embodiment, also parallel connection one the between the second input I2 and the 3rd output end O3
Six diode DF2, the 6th diode DF2 positive pole are connected with the 3rd output end O3.
Specifically, in the above-described embodiment, the driving referring now to a kind of serial connection controllable silicon control circuit of the present invention can
The mode of control silicon is further detailed with method.
Driving the method for controllable silicon needs：Reliable driving current, it is necessary to realize zooming larger current in the early stage
Numerical value, after counting microsecond, it is desirable to provide a metastable lasting relatively low driving current.High impulse currents forward position and relatively low
Maintenance electric current, can make drive circuit reliability and driving power consumption realize reasonable balance.
As shown in figure 1, when switching switch S1 is in long off-state, because the 4th diode DD1 cathode voltage is more than
Its cathode voltage, now the 4th diode DD1 holdings cut-off state；3rd electric capacity CD1 carries out filling energy by the 4th resistance RD1,
Until the voltage at the 3rd electric capacity CD1 both ends is equal with the 4th diode DD1 both end voltages, now no storage is appointed in transformer TF
What energy.
After switching switch S1 enters duty cycle pattern, frequency high switching switch S1 mono- is switched, when
When switching switch S1 is begun to shut off, the electric energy of the first power end VDH+ offers, and the 3rd electric capacity are stored on the 3rd electric capacity CD1
Voltage on CD1 is higher so that the both ends of the coils of transformer TF second have higher pressure drop, and this avoid existing in circuit
The obstruction of leakage inductance so that output current rapid increase.
Magnet ring T1 the first coiling group higher pressure drop is transferred in the second coiling group, due to the coil turn of the first coiling group
Less than the coil turn of the second coiling group so that the second coil output voltage further increases.Further cause differentiator K1a
Export a higher voltage, the high voltage of output is with activation driving controllable silicon Q1 so that controllable silicon Q1 can enter work
Make state, while cause the second electric capacity C1b to carry out filling energy.
Because the 3rd electric capacity CD1 capacity is relatively small so that the logical CD1 of the 3rd electricity charging duration is more than duty cycle
The switch duration of switching switch S1 under pattern, the electric energy consumption stored on the 3rd electric capacity CD1 after several duty cycles
To the greatest extent, the electromotive force on the 4th diode DD1 negative poles is caused to deteriorate to less than second source from the first power end VDH+ voltages rapidly
VD+ electromotive force state is held, now the 4th diode DD1 is switched on, and the electric current passed through is provided by second source end I2VD+.
After magnetic force energy in magnet ring T1 runs out of, because not extra energy enters to advance into the second electric capacity C1b
The transmission of one step, the second electric capacity C1b start outside power output, and the power that the second electric capacity C1b is outwards exported is controlled by current stabilization
Device M1 carries out current constant control, and because the second electric capacity C1b capacitor's capacity is larger, now the second electric capacity C1b is to outside power output
It is sufficient so that controllable silicon Q1 and obtains a stable driving current.
After several pulse periods, the electric energy on the first electric capacity C1a is supplemented with money to a higher state, and now second
Resistance R1b voltage is higher than its input voltage so that differentiator K1a output currents are very faint.
As shown in figure 1, when duty cycle end cycle, now whole system enter it is long disconnect off status, due to the
One diode D1a presence prevents the first electric capacity C1a output current from being output to magnet ring T1 by the first diode D1a
In, the electric capacity on the first electric capacity C1a is discharged by second resistance R1b, and the first electricity logical R1a discharge times are less than long off-state
Duration.The electric energy on the 3rd electric capacity CD1 is full of within the duration of long off-state simultaneously.
Second coiling group provides energy when drive circuit duty cycle works, and the 3rd coiling group is in drive circuit pulse
During long off-state, by the energy transmission in magnet ring T1 to being sent to drive circuit, the coil of usual 3rd coiling group
The number of turn is less than the coil turn of the second coiling group, to realize that magnet ring T1 resetting time is less than positive unlatching event, it is ensured that cut
Switch S1 magnet ring T1 during long disconnect are changed to reset completely.
When whole system is from duty cycle cycle transition to factory's off-state, the leakage inductance on whole system circuit can also store up
Deposit certain energy.This portion of energy is led to the 6th diode DF2 and is delivered on first input end I1VDH+.First power end VDH
+ S1 closing process formation clamping action is switched to switching, while realize the mistake when recovery of energy and switching switch S1 are closed
Pressure limitation.
During long off-state, the leakage inductance energy in circuit is sent on the VD+ of second source end by transformer TF.
First coiling group of magnet ring T1 to magnet rings all magnet ring Tn is connected by a wire.The wire has leakage inductance,
Shut-in time section during duty cycle, the energy storage in wire that all magnet rings connect can not be ignored, and this part
Energy can not be sent on controllable silicon.Transformer TF, the 5th diode DF1 and the six or two are configured with whole circuit
Tri- elements of pole pipe DF2, realize the recovery of leakage inductance energy, improve the efficiency of whole drive circuit, relative to not reclaiming Lou
The scheme of sense, the input power of whole system can be reduced.
Preferred embodiments of the present invention are these are only, not thereby limit embodiments of the present invention and protection domain, it is right
For those skilled in the art, it should can appreciate that and all be replaced with being equal made by description of the invention and diagramatic content
Change and obviously change resulting scheme, should be included in protection scope of the present invention.
