The maglev train is a new modern rail transportation tool, which changes the current of the suspension electromagnet according to the input control instruction, so as to adjust the attraction of the suspension electromagnet to the steel track, so that the maglev train is suspended stably. This paper introduces the PWM soft switching chopper based on the soft switching converter and the suspension chopper, which can completely realize the zero voltage opening and closing of the main switch, reduces the system loss, improves the efficiency of the power supply transformation, and improves the working conditions.
