This paper introduces a kind of repetitive frequency pulse driving source based on electrical triggering technology, which breaks through the key technologies such as pulse shaping of double capacitor structure, high voltage generation of compact structure and repetitive frequency stable operation under high current conditions. The simplest Marx voltage Overlay technology to solve the technical difficulties of Marx in the repetition frequency operation. Pulsed power drive source design output power 20GW, pulse width 180ns, repetition frequency 1 ~ 50Hz, output power and repetition frequency adjustable in a certain range. The developed pulsed power drive source has a volume of only 2.5m ~ 3, a weight as low as 2.2t, an impulse energy density of up to 23kJ · m ~ 3 and a output power of about 20GW in a single operation of the driving source. Under the working condition of 30 Hz, the output power is 16GW, the continuous running time is 10s, the system jitter is about 6ns, and the system runs stably and reliably.
