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.
