| Abstract |
Input current of conventional capacitor input diode rectifiers widely used in high frequency switching power sources present a low power factor and contain many harmonics, which cause many troubles to the power system. This paper proposes a new approach to improve the current waveform of capacitor input rectifiers, which is based on the dither effect used in the linearization of non- linear function in control systems. Two applications of the dither rectifiers are presented in this paper: a switching regulator and a high-frequency current-type inverter. They can be realized by simple modifications in conventional circuits, and more importantly, no control is needed. The experimental circuits achieved over 99% input power factor and current distortion below 11 %. |
