ZVZCS SWITCHING CONVERTER USING AUTO-TRANSFORMER

摘要

According to an embodiment of the present invention, a switching converter is provided. The switching converter comprises: an autotransformer which has a main winding wire including a first winding wire and a second winding wire connected in series with the first winding wire, and a tab connection at a contact point between the first and second winding wires, wherein one end of input power is connected to one end of the main winding wire; an active switch which is connected between the tab connection and the other end of the input power; a snubber circuit which is connected in parallel to the active switch; a link diode whose one end is connected to an output of the snubber circuit; a clamp diode which is located between the other end of the link diode and one end of the conversion output; a healing capacitor which is located between the other end of the main winding wire and a contact point of the link diode and clamp diode; and an output diode which is located one end of the transformation output and the other side of the main winding wire.
