In this paper, it is presented a configuration to miniaturize HPCU (Hybrid vehicle Power Control Unit) and a control strategy using FPGA logic. To miniaturize the HPCU, the film capacitor is used as a DC-link capacitor instead of the electrolytic capacitor. Additionally, for the minimization of control hardware, a FPGA based controller is used to control multi-module of power converter. To verify the feasibility of the control strategy and FPGA based control hardware, the laboratory based load test is performed. With FPGA based hardware, the sampling frequency of the digital current control loop can be increased by 30% compared to DSP software based control system.
