The reluctance method keeps the , performance when designing offline Flyback power supplies. The basic problem is the presence of the various leakage inductances of the transformer. Those leakage inductances cause voltage overshoot (which, in turn, calls for power switches with increased voltage rating), divert a portion of the primary current to a clamp, and degrade the voltage regulation in power supplies with primary regulation or with multiple
