Abstract

Suspension chopper is a high-power electrical equipment for vehicle suspension control. Its performance is crucial to the stability, reliability and comfort of maglev trains. There are a series of problems in the traditional chopper using the H-bridge hard switching mode, especially the problem of voltage spike which cannot be ignored for high-speed maglev trains. In this paper, a phase-shifted full-bridge zero-voltage suspension chopper is proposed, which uses the phase-shifted control signal to realize IGBT zero-voltage turn-on and zero-voltage turn-off, so as to reduce the voltage spike. Firstly, the working principle and control modals of the phase-shifted full-bridge suspension chopper are analyzed. Then, the simulation and experimental test platform are built to verify the effect of reducing the voltage spike. The results show that the phase-shifted full-bridge suspension chopper can effectively reduce the voltage spike, which provides a reference for optimizing and improving the high-speed maglev chopper.
