Abstract
A flyback-type power converter having a secondary-side resonant circuit which shapes the current waveform in the secondary winding and secondary circuit to reduce the RMS current values therein is described. The shaping reduces conduction losses and improves conversion efficiency. With the resonant circuit, the energy stored in the transformer is transferred during the OFF-period in substantially a fixed time duration, enabling a fixed-OFF period operation mode. The converter may further have a primary-side resonant circuit for capturing and recycling the energy stored the leakage inductance of the primary winding, which is normally wasted in snubber circuitry.
