Operation principle of the invention：It is that long-pulse discharge is divided into the short discharge pulse electric discharge of continuous multi-stage, long pulse is washed open
Mended in the main high-voltage energy storage part of first paragraph of beginning and section and fall part start-up operation, main high-voltage energy storage partial switch turns on discharge capacity
Voltage declines, and is mended in section and falls electric capacity C31Charging voltage synchronously begins to ramp up, and total voltage pulse output is constant, as electric capacity C31Voltage
Rise to segmentation benefit and fall electric capacity C2iMagnitude of voltage when, switch K3Immediately from electric capacity C31High-end disconnection be transferred to magnitude of voltage for zero volt
Electric capacity C32It is high-end on, while mend fall switch K21Electric capacity C is supplied in closure conducting31The magnitude of voltage of disconnection, mends segmentation and falls electric capacity C21
With main storage capacitor C11Discharged in series, first paragraph pulsed discharge and benefit are fallen end and enter second segment.During second segment works, point
Section is mended and falls electric capacity and the decline of main energy storage capacitor in series discharge voltage, is mended in section and is fallen charge power supply E3Start to fall electric capacity C to benefit in section32
Charging voltage synchronously rises, and makes total output voltage constant, electric capacity C31Electric discharge, as electric capacity C32Voltage rises to benefit and falls electric capacity C2i's
During magnitude of voltage, K is switched3Immediately from electric capacity C32High-end upper disconnection be transferred to voltage and discharged into zero capacitance C31It is high-end on,
Mend simultaneously and fall switch K22Closure conducting, supplies electric capacity C32The magnitude of voltage of disconnection, segmentation benefit falls electric capacity C22Also assist in main storage capacitor
Electric discharge, second segment electric discharge terminate enter the 3rd section electric discharge, by that analogy, until long pulse terminates.
The method for designing of relevant parameter of the present invention：
1) the pulse voltage U of clear and definite high-voltage pulse power source requirementm, pulse power Pm or pulse current Im, pulse width time t,
And the power supply power P that client can providein, and pulse voltage allows to fall value △ U；
2) according to pulse current ImFall magnitude of voltage U with being mended in output power design segments3, I can be made3Equal to (1.1~2.0) Im, must note
Mended in meaning section and fall electric current I3Big and electric capacity C3iBigger, pulse top is more smooth, but its power attenuation is also big；Fall electric current when being mended in section
I3It is determined that after, U3=Pin/I3, thus can mend in select segment and fall electric capacity C3iMagnitude of voltage.The magnitude of voltage is also that segmentation benefit falls part often
The capacitance voltage value U of group2；When output power is smaller, power supply is only mended for section is interior and falls electric capacity charging during selection electric discharge；
When output power than it is larger when, can consider to be mended in selection section and fall the power of power supply, surplus power allows power supply in main storage
Can electric capacity C1iSome energy are also provided during electric discharge, can further reduce main storage capacitor C1iValue；
3) parameter for falling part is mended in design alternative segmentation, and segmentation benefit is fallen mend interior equal to section of every group of part voltage and falls voltage first, often
After group voltage determines, the group number that segmentation benefit falls part will consider selection；Segmentation benefit falls portion's packet count more, main storage capacitor
C1iAllow Voltage Drop bigger, main storage capacitor C1iCapacity is smaller, but group number can increase difficulty of processing too much.It is 1 for pulsewidth
The long pulse of second, may be selected 30~50 groups.Main high voltage energy-storage capacitor allow drop-off voltage just become by the △ U for specifying (30~
50)△U.It is also contemplated that the time of total pulsewidth mends the magnitude of voltage mended in the group number and section that fall part and fall part with segmentation；
4) main storage capacitor C1iCapacitance value design alternative, calculate first without segmentation benefit fall part and section in mend fall part when,
In the range of the Voltage Drop that user allows, IT=C △ U, C=IT/ △ U；The capacitance calculated by this traditional formula can be very big,
Price is very high, and volume weight is all very big；By the solution of the present invention, it is contemplated that take 1/30~1/50 work of traditional storage capacitor capacity
It is main storage capacitor C1iCapacitance；
5) the main high-voltage energy storage charge power supply E of main high-voltage energy storage part1, main storage capacitor C1iAnd discharge switch K1i, can both use
Packet-type, it is also possible to be grouped profile.
Compared with traditional high-voltage pulse power source, present invention has the advantages that：
1st, high-voltage pulse power source of the invention can be greatly reduced the appearance of high-voltage energy storage capacitor on the premise of functional parameter is met
Amount, so as to the cost of manufacture of high-voltage pulse power source is greatly reduced, reduces equipment volume weight, and improves high-voltage pulse power source using
Safety and reliability, user is obtained high performance high-voltage pulse power source with relatively low expense；
2nd, high-voltage pulse power source of the invention can also improve the functional parameter of the pulse power on the premise of functional parameter is met, and make
Pulse top voltage is without falling, and pulse top is smoother；
3rd, high-voltage pulse power source of the invention, due to the storage energy of high-voltage energy storage capacitor is greatly reduced, strikes sparks in load
When be easier protection, therefore improve the security of high-voltage pulse power source；
4th, for main high-voltage energy storage part main high-voltage energy storage charge power supply, main storage capacitor and discharge switch are distributed using packet
The high-voltage pulse power source of type is more due to being taken when the group number of main high-voltage energy storage part is designed and segmentation is mended and falls the group number of part
Group redundancy group number design, and Fault Isolation measure is all taken at every group, when one of which or it is multigroup break down when, equipment
Normal work is remained to, therefore improves high-voltage pulse power source reliability of operation.
