| Abstract: | This paper describes a special designed and built dc chopper for electric cars. The power switching device is bipolar junction transistor (BJT) module. Advanced techniques including fast protection against desutuaration of BJT and passive low loss snubber circuit configuration, accompanied with maximum starting current control strategy and system protections such as overcurrent, over and under voltage, ensure the chopper to have a small size, light weight, high operation efficiency, fast dynamic response, and high reliability. Test results on a modified MAZDA electric car employing the above described chopper have proved the excellent performances mentioned in this paper. |
