As various kinds of domestic electrical goods and office automation equipment have become more widely used, interference from harmonic currents, which are generated from home appliances, has become a problem. Therefore, A power factor correction, PFC, converter has been developed to reduce harmonic currents. In this paper, suitable for a single-phase sinusoidal current input converter. This method provides a sinusoidal input current without using an input current having a standard sinusoidal wave-form. Experiments showed that the method worked effectively. Therefore, we found that it is possible to control harmonic currents and thus improve the efficiency of a PFC converter.
