초록
At the high speed operation, the boost negative bias can reduce the negative torque and increase the dwell angle, so the output power and efficiency can be improved. In this paper, a novel power converter for single phase SRM with boost negative bias is proposed. A simple passive capacitor circuit is added in the front-end, which consists of three diodes and one capacitor. Based on this passive capacitor network, the two capacitors can be connected in series and parallel in different condition. In proposed converter, the phase winding of SRM obtains general dc-link voltage in excitation mode and the double dc-link voltage in demagnetization mode. The operation modes of the proposed converter are analyzed in detail. Some computer simulation and experimental results are done to verify the performance of proposed converter.
