The static power converter has become very useful in electric vehicle battery charger, because of its ability to convert electrical energy from AC system to DC system. The characteristic of a static power converter as a load is non-linear. Electric vehicle charger is a potential for power quality problems and could have a significant detrimental effect On a utility transmission and distribution line. The major power quality problems may be power factor degradation, current harmonics, and energy efficiency. Recently, a new family of buck-type single switch high power factor rectifier as introduced which has continuous input current and constant output current. By using of multi-resonant scheme, the transistor can operate with zero current switching, and the diodes operate with zero voltage switching. This rectifier is capable of drawing a high quality input current waveform at nearly unity power factor with a single transistor.
