ABSTRACT:
A family of DC-to-DC converters includes a multi-resonant snubber network connected in parallel with a power switching device. The multi-resonant snubber network includes an auxiliary switch that is connected to transfer the energy from a parasitic capacitance of the power switching device into a resonant inductor and to achieve zero-voltage turn-on of the power switching device. An additional resonant path is included in the snubber network to achieve zero-voltage turn-off of the auxiliary switch and the power switching device.
