燃料电池电动汽车(FCEV)动力装置由燃料电池与超级电容(SC)分别通过DC/DC变换器并联构成供电电源,其中DC/DC变换器采用电压电流双PI调节器,在频域分析法设计调节器参数基础上构建硬件平台进行实验,实验结果与理论分析结果具有一致性。
Power supply of fuel cell electric vehicle(FCEV) is constituted by fuel cells and supercapacitors(SC).Fuel cells and SC are connected in parallel to supply the inverter of the motor.Voltage PI and current PI controller are used in the DC/DC converter of fuel cells and SC,and the suitable controller parameters are designed by frequency domain analysis.Experimental platform is established to verify the experimental results being consistent with theory.
