摘要：
In order to simplify the isolated synchronous driving of many switches in all solid-state bipolar pulse adders, in this paper, a self-triggering bipolar pulse adder is proposed. This circuit combines self-triggering drive circuits with special full-bridge circuits, only two isolated signals are provided to control the first switch of the positive or negative polarities, and all other switches can be automatically triggered on and off through the self-triggering circuits, thus generating bipolar high-voltage pulse. Moreover, the structure design, working principle and parameter design of the circuit are analyzed, and the feasibility of the circuit is verified by the Pspice simulation. A prototype of a 15-stage pulse adder was built. The experimental results show that stable repetitive frequency bipolar pulses can be obtained over a 10 kΩ resistive load. Positive and negative pressure amplitudes from 2 to 5 kV, pulse width from 1 to 10 μs, and frequency of 1 kHz can also be obtained. The pulse adder has the advantages of small size, compact structure and module design, providing technical support for the development of miniaturized pulse power supply. © 2023 Science Press.
