Abstract: A device is configured to detect a zero voltage switching (ZVS) circuit output that includes a hard switching signal. The hard switching signal includes a false signal and a spike signal. Thereafter, the device generates digital pulse signals that correspond to the false signal and the spike signal. Accordingly, the device filters the generated digital pulse signal that corresponds to the false signal, and uses the digital pulse signal that corresponds to the spike signal for adjusting a timing of a pulse width modulation (PWM) switching cycle.

Abstract: A circuit includes a zero current detector (ZCD) circuit that senses an inductor current of an inductor and generates signal pulses indicating when an increasing cycle of the inductor current crosses a predetermined current value and when a decreasing cycle of the inductor current crosses the predetermined current value. A sync control provides a control signal specifying one of the signal pulses corresponding to the increasing or decreasing cycle of the inductor current. A sync selector circuit generates a sync pulse representing the signal pulse from the ZCD in response to the control signal. The sync pulse triggers a timing adjustment for a switch device.
