Abstract

The invention discloses a pulse generator which comprises two basic units with the same structures. Each basic unit comprises an inductor, a diode, a capacitor and a controllable switch unit, one end of each inductor is connected onto a second end of the corresponding controllable switch unit, the other end of each inductor is connected onto the second end of the corresponding controllable switch unit through the diode and the capacitor sequentially, one ends of the two inductors in the two basic units are connected to serve as an input end of the pulse generator, first ends of the controllable switch units in the two basic units are connected to serve as the other input end of the pulse generator, and ends, corresponding to each other, of the inductors in the two basic units serve as output ends respectively. By the pulse generator, input direct-current voltage can be converted into pulse voltage, the leading edge and the lagging edge of output pulse voltage are precipitous, the pulse top is flat, and components adopted are common components, so that the pulse generator is simple in structure and convenient to popularize and utilize.

Description

technical field [0001] The invention relates to a power conversion device in the technical field of power electronics, in particular to a pulse generator. Background technique [0002] Pulse generators are commonly used power electronic converters, widely used in pollution control, food processing, laser power supply, nuclear physics and other fields. [0003] High-power bipolar pulse sources are widely used in waste gas treatment, food sterilization, material modification, PDP and many other aspects. The structure of the high-power bipolar pulse source currently used is complicated, the pulse edge is not steep enough, and the efficiency is low. The pulse generator based on solid-state devices has attracted more and more attention due to its advantages of high efficiency, flexible control, and small size. The high-power bipolar pulse source based on solid-state devices takes advantage of the small distributed capacitance of solid-state devices. And the high-speed character...
