Classification: CPC H  B | IPC B  H

Claim 8:
9. A system comprising:
a power supply configured to produce a voltage within a predetermined voltage range;
a power converter circuit, the circuit comprising:
an input terminal configured to receive from the power supply, the voltage within the predetermined voltage range;
an output terminal;
a transformer configured to isolate an output terminal of the circuit from an input terminal of the circuit, wherein the transformer includes a leakage inductance and a magnetizing inductance;
a resonance capacitor in series with the leakage inductance, wherein a value of capacitance for the resonance capacitor, a value for the magnetizing inductance and a value for the leakage inductance configure the circuit to operate in resonant discontinuous conduction mode (DCM);
a switch node;
a clamping switch;
a main switch; and
a loop controller configured to:
drive control terminals of the main switch and the clamping switch;
operate the power converter circuit with a dead time:
wherein both the main switch and the clamping switch are off during the dead time, and
wherein a voltage at the switch node transitions between a first voltage magnitude and a second voltage magnitude within the dead time.
