Abstract

In the context of vehicle-to-grid (V2G) applications, single-port bidirectional inductive power transfer (BDIPT) systems have difficulty coping with the growing demand for electric vehicles. This paper proposes a multi-port BDIPT system based on an LCC-LCC compensation network. A multi-phase-shift (MPS) control with more degrees of freedom is proposed, where the external phase shift angle controls the power transmission direction and the internal phase shift angle controls the transmitted power magnitude. Independent multi-port operation for the multi-port BDIPT system can be achieved. Finally, the theoretical results are verified by experiments. The experimental results show that the LCC-LCC-based multi-port BDIPT system can achieve independent control of the transmission power at each port.
