Research of a novel flexible load for electric vehicle test bench
Energy and environment problems have been becoming more and more serious. Either electric power corporations or traditional automobile enterprises have taken part in novel electric vehicle development. Whatever, Variable and dynamic loads are required in order to satisfying variable working conditions in the electric vehicle (EV) experiments of the traffic. The scheme of power electronic impendence converter which adopts buck topology is brought forward to reach this goal. Impendence converting can be implemented by controlling converter's duty cycle. Then, the load torque is simulated by changing the variable load's value. At last, the experiments show that the scheme is simple, feasible and cost-efficiency.
