Abstract :
Energy recovery in the regenerative region is very important when SRM is used in a traction drive. This is to reduce energy loss during mechanical braking and/or to have a high efficiency drive during braking. To control excitation voltage in motor operation and regenerative voltage in the generator operation in the SRM, multi-level voltage control is effective. This paper suggests a multi-level inverter which is useful for motoring and regenerative operation in SRM
