Abstract: To realise the driving and regenerative braking of a battery electric vehicle, the hardware circuit and the software flowchart are designed based on digital signal processor (DSP) in detail. The power electronics design and application for the energy recovery controller is presented. The snubber circuit of large power insulated gate bipolar transistor is given with emphasis. The control targets are analysed for the driving and regenerative braking, in which the motor current is defined as the target for the former and the constant regenerative braking current control strategy for the latter, respectively. Both the indoor experiments and the outside experiments are carried out to validate the feasibility, stability and reliability of the energy recovery controller based on DSP and power electronics.
