Copolar Synchronous Switching Method for BLDC Motor Control in EV Application

Copolar Synchronous Switching Method for BLDC Motor Control in EV Application

This paper proposes a new PWM switching method, called copolar switching, for synchronous rectification in brushless DC motors (BLDC). This method-integrates the benefits of both unipolar and bipolar switching, addressing the efficiency trade-off commonly observed in low-resistance BLDC drives. Unip...
