Resonant converter

In switching power supply circuits, a converter circuit that reduces switching loss through LC. Broadly classified, there are two types: voltage resonant converters and current resonant converters. Voltage resonant converters have superior voltage-current characteristics at power-off (turn-off), while current resonant converters have superior voltage-current characteristics at power-on (turn-on). Therefore, both types have the advantage of reducing switching loss compared to non-resonant converters. Compared to non-resonant converters, they offer the benefits of higher efficiency, smaller size, and less noise, making them widely used as AC-DC converters.
