Forward converters used in switching power supplies

Abstract From the Canadian patent

Abstract, A forward converter periodically resets the transformer core to prevent saturation and returns magnetizing energy to the energy source requiring only, the addition of one resonating capacitor to the converter circuit. The transformer is reset and the energy recovered into the input voltage source by resonant commutation of the magnetizing current between the magnetizing inductance and a resonating capacitor. A resonant current path is completed during a nonconducting interval of the power transistor switch through the resonating capacitor, shunting the output rectifying diode connected to the secondary winding and, the flyback diode of the output filter to permit transfer of the …
