摘要

针对内燃机车变频器受开关频率限制的问题，通过采用分段调制方法来研究不同模式PWM之间的切换条件，实现异步PWM、同步PWM、SHEPWM PWM和方波之间的平滑过渡。试验也验证了切换策略的正确性。

Abstract

According to the restriction of switching frequency in diesel locomotive converter, a subsection modulation technique was used, the transitive strategy was proposed to realize smooth transition of individual modes including the asynchronous PWM, synchronous PWM, SHEPWM and the squire waveform. The experiment results proved the validity of the strategy.
