• "Recycles" transformer magnetizing energy instead of dissipating it in a resistor
• facilitates Zero Voltage Transistion of the main switch for higher efficiency
• uses lower voltage MOSFET and diodes compared to the RCD
• reduced EMI/RFI via soft switching
• eliminates lossy snubber network on primary
• operates at fixed frequency
• allows much higher frequency operation
• similar power transfer to conventional sqaure wave switching
• duty cycles beyond 50% are obtainable
• actively resets main transformer to third quadrant of BH curve
