Abstract

This paper proposes a dynamic capacitive power transfer (CPT) system which utilizes electric fields to transfer power to a moving receiver. The transmitter is a long track, consisting of a pair of aluminum plates. One important property of this transmitter structure is reducing the power pulsations at the receiver. The receiver also consists of a one pair of aluminum plates that are capacitively coupled with the transmitter plates. The capacitive coupling delivers power to the receiver. An LCLC compensation topology is used at both the transmitter and receiver sides to provide resonances which boost the plate voltage in order to transfer power. A 150W prototype of a dynamic CPT system is designed and implemented. Each transmitter plate size is 1200mm×300mm, and each receiver plate size is 300mm×300mm. The switching frequency is 1.5MHz, and the DC-DC efficiency reaches 85.4%. When the receiver moves along the transmitter track, the output power varies within ±4.0% of the nominal power.
