Abstract: A soft switching resonant converter is disclosed. The converter includes a power switch operable to connect and disconnect a DC link rail node and an output node. A resonant capacitor is coupled with the power switch. An auxiliary leg is coupled with a DC link midpoint node and the output node. An active damper is coupled in series with the resonant capacitor and the output node and is controllable to provide a first resistance of the active damper in a first state and a second resistance of the active damper in a second state, the first resistance having a lower magnitude than the second resistance. A driver controls the damper switch to provide a first resistance during the soft switching operation of the power switch and a second resistance after the soft switching operation of the power switch.

Abstract: A zero voltage detection device may include a voltage divider that scales down a first voltage to a second voltage, a comparator that compare the second voltage to one or more voltage thresholds and outputs a first set of signals indicative of an estimation of the first voltage approaching a zero-voltage instant, the one or more voltage thresholds configured to compensate for a time delay from the voltage divider, a flip flop that obtains the first set of signals and outputs a second set of signals to control a switching operation of a switching device, and a control system that obtains the second set of signals during a defined time window and that forces the switching device to turn on at an end of the defined time window if the second set of signals is not detected to limit turn-on losses.
