Abstract

The invention discloses high voltage fast pulse power supply based on a DSRD. The high voltage fast pulse power supply based on the DSRD is characterized in that a pump circuit of the DSRD is an inductive adder pump circuit which comprises M pulse power modules. Each pulse power module comprise a switch S1, a switch S2, an energy-storage capacitor C0, a resonant capacitor C1, a n:n turn resonancetransformer T1 and a 1:1 turn transformer T2. One end of each S1 is grounded and primary of each T1 is connected to the other end of each S1 through each C0, the other end of the primary of each T1 isgrounded, the other end of each secondary of each T1 is connected with primary of each transformer T2 separately through each resonant capacitor C1 and is grounded through each switch S2, and the other end of the secondary of each resonance transformer T1 is connected with the other end of the primary of each transformer T2 and is grounded separately. The secondary of each transformer T2 of eachpulse power module is stacked and connected in series together to provide a bidirectional pumping pulse for a DSRD stack. The high voltage fast pulse power supply based on the DSRD solves the problemof pulse power stacking of a high repetition frequency DSRD fast pumping circuit.
