Abstract In multilevel converters, strong galvanic isolation and insulation are usually realized by the transformer. Based on ultrasonic contactless power transfer(UCPT), a novel gate driver supply is proposed, which mainly includes transmitting transducer, receiving transducer, acrylic column medium, compensation circuit. The design of these key elements is analyzed in detail, and the equivalent circuit of the transducer is described. To simulate the transducer, the FEM software COMSOL is used and the simplified equivalent circuit is proposed. The compensation methods both at the transmitting side and receiving side are analyzed in detail. An experiment prototype is built to verify the compensation method. The ultrasonic contactless power transfer and inductively contactless power transfer are compared, which shows that the UCPT technology has strong anti-electromagnetism disturbance ability. At last, the experiment shows that the power supply proposed can drive the full-bridge module, especially suitable in complex electromagnetic environment.

Key words： Contactless power transfer ultrasonic contactless power transfer compensation circuit gate driver supplies
