DSP Based Regenerative Brake Controller for a BEV

摘要

To realize the accelerator and regenerative braking of a BEV,the hardware circuit and the software flowchart are designed based on DSP in detail.The snubber circuit of large power insulated gate hipolar transistor is given out with emphasis.The control targets are analyzed for the accelerator and regenerative braking,which the motor current is defined for the former and the constant regenerative current control strategy for the later.Both the indoor experiments and the infield experiments are carried out to validate the feasibility,stability and reliabilitv of the regenerative hrake controller.
