Interference from harmonic currents which are generated from home appliances has becoming a problem with popularization of various kinds of domestic electrical goods and OA equipment. This paper describes a new method to improve the power factor of a single phase sinusoidal current input converter. The method provides a sinusoidal input current without using an input current of sinusoidal standard wave form. Experiments confirm the power factor is about 100%. Moreover, the converter can be applied to speed control of DC brushless motors. For this purpose a new control method is proposed. The method uses a PWM control mode for the inverter under light load and a PAM control mode for the converter under heavy load. Overall, this improves efficiency. © 1994, The Institute of Electrical Engineers of Japan. All rights reserved.
