A shared traction drive and battery charger modes for Plug-In Hybrid Electric Vehicle application

In this article, we will focus on a 5kW three phase converter for Electric Vehicle (EV). The principle is to use the same converter for traction mode and battery charging sequences. The charger will be controlled in PFC in order to reduce current harmonics rejections. Two types of charging mode will be realized thanks to this structure. A fast charging mode with a 3-phase double-boost, and a single phase low power charging mode assumed by an interleaved PWM rectifier. Passive elements will be designed in each converter mode, with considering high frequency currents in all the designed elements. An experimental test bench has been developed in order to validate the theoretical study. The control will be implemented into a National Instruments SBRIO-9683, composed by a Power PC processor running a Real Time application, and an FPGA.
