Abstract
A flyback converter is provided, which includes a transformer comprising a primary winding and a secondary winding, the transformer for transforming a power inputted from an input power supply and outputting the transformed power, a switching part having one end connected to the primary winding and the other end connected to the input power supply, and an auxiliary circuit including an auxiliary capacitor, and an auxiliary winding coupled to the primary winding. In addition, a clamping diode and a two-series connected switch structure is utilized for the switch stage to relieve the voltage stress of the switch. Accordingly, it is possible to reduce the voltage stress of the switch and also reduce the ripple of the input current which are the causes of EMI.
