Abstract
There is provided a boost converter capable of reducing voltage stress within each element thereof, without using a separate loss snubber circuit, by clamping a voltage applied to an output diode to correspond to a difference between an input voltage and an output voltage. The boost converter includes a transformer including a primary winding receiving an input power and a secondary winding electromagnetically coupled to the primary winding and having a preset turn ratio therewith; a switching unit switching the input power transferred to the primary winding on and off according to a preset duty ratio; a stabilizing unit including an output diode rectifying the power outputted from the secondary winding to stabilize an output power; and a clamping unit clamping a voltage applied to the output diode to correspond to a difference between the input power and the output power during a switching on operation of the switching unit.
