Study on Strengthened Synchronism of SRM Using a PLL

PLL을 이용한 SRM의 동기화 강화에 대한 연구

This paper suggestes a SRM drive scheme which include power angle control like synchronous machine and a Phase Locked LooP(PLL) control. The power angle control scheme regulates instantly dwell angle as load torque variation, but this is some disadvantages which are losing of synchronism and hunting when load changes abruptly. To increasing synchronism, the Phase Locked Loop control scheme is adopted.
