A Novel Resonant Converter for driving Switched Reluctance Motor
초록
In order to obtain better performance for a SRM(switched reluctance motor) drive, the commutation from one phase to another must be as fast as possible. In this paper a novel converter for SRM drive is proposed, which can accelerate the turn-off and turn-on time by using two capacitors to form a resonant circuit with the motor inductance. Two capacitors recover rapidly stored energy in the off going phase and establish rapidly the current rising in the on going phase. As a result, the current tail can be shortened and the dwell angle in the positive torque region can be extended. And comparing with the asymmetric converter, this converter has higher energy availability in energy conversion process and less number of switches.
