摘　　要：在变频调速系统中,其开关频率的提高主要受到开关损耗的限制,从而导致谐波较大、电网污染及电机噪声等。要提高开关频率可采用使开关损耗为零的方法,使之只受器件的固有参数限制。本文提出一种零开关损耗的谐振直流环节变频器拓扑,以及相应的控制策略,理论和仿真证明了其方法的可行性,具有优良的性能。In inverter motor drive system,the main factor which affects the increase of switching frequency is the switching loss, so that large harmonic component in output of inverter, power supply deterioration and motor noise etc are resulted in. Zero switching loss can be used to make it affected only by inherent characters of devices. The paper presents a zero switching loss resonant DC link inverter topology and its control strategies. The method is proved to be available and have good performances from theory and simulation.
