摘要

The development of fast and low cost switching devices resulted in large use of high frequency power sources also in small equipments for home use. The capacitor input type rectifier is widely used in such equipments owning to simple configuration and high efficiency, but the effect of the harmonics present in its input current to the power system is becoming not negligible. Therefore, rectifiers with sinusoidal input current is strongly desired.
