Design of A Low Power Switched Reluctance Drive based on IR2113

摘要

Power converter, which is the heart of SRM drive, should be designed reasonably to make the system efficient and reliable. Therefore, a switched reluctance motor drive based on IR2113 is proposed in this paper. The power converter is analyzed and its unique drive circuit and the bootstrap circuit are designed. Moreover, to improve the protection performance of the system, an over-current protection circuit and an overheat protection circuit are built. Experimental results show that this system can work reliably.
