Abstract:
A power converter includes a primary side with switch devices that form a power transfer stage, and a secondary side with switch devices that form a rectification stage and an output filter coupled to the rectification stage and including an output inductor and output capacitor. A transformer couples the primary and secondary sides. The switch devices are controlled in DCM (discontinuous conduction mode) to transfer energy from the primary side to the secondary side during a power transfer interval in which one branch of the power transfer stage is conducting, one branch of the rectification stage is conducting and another branch of the rectification stage is blocking. As a voltage of the transformer first begins to rise at the start of a new power transfer interval in DCM, the branch of the rectification stage that is to be conducting during the new power transfer interval is hard switched on.

Claim (Index 15):
The method of  claim 12 , wherein hard switching on the branch of the rectification stage that is to be conducting during the new power transfer interval comprises:\n hard switching on the branch of the rectification stage that is to be conducting during the new power transfer interval after a delay from when the controller activates the branch of the power transfer stage that is to be conducting during the new power transfer interval, and wherein the delay is given by: delay = 2 * \u00a0 \ue89e \u03c0 * ( L r + L lkg ) * ( Coss SRx 2 ) 2 , where L lkg  is leakage of the transformer, L r  are stray inductance and external resonant inductance, and Coss SRx  is capacitance of the branches of the rectification stage which store charge between power transfer intervals due to resonance that occurs on the secondary side during DCM.
