Abstract

In this paper, a novel ZCS-PWM control method for micro-turbine excitation control system is proposed. The method of main circuit parameters design is developed. And the timing of the main switch and the assistant switch in main circuit is calculated for achieving the excitation control in double IGBTs switching mode. The application in real world proves that switching loss is greatly reduced by using soft-switching technique compared to that using hard switching technique.
