Abstract
In this paper, bilateral variable-ratio dc chopper system for electric vehicle is proposed. We present the method which is able to simplify the main synthetic chopper circuit by selecting among the forward powering, forward regenerative braking, backward powering, and backward regenerative braking only by control signal. By conducting the experiment with separately excited dc motor, it is confirmed that two quadrant chopper can drive four quadrant operation.
