An inductive power transfer (IPT) system usually consists of four parts: an ac-dc power factor correction (PFC) converter, a high-frequency dc-ac inverter, a compensation network comprising a loosely coupled transformer (LCT) and the resonant capacitors, and a rectification output circuit. Due to the relatively large air gap, the magnetic coupling coefficient of the IPT system is significantly lower than that with tightly coupled transformer. As a result, the efficiency of the IPT system is… CONTINUE READING
