Single phase high power factor rectification is the most frequently accomplished using a boost converter. The input current shaping approach results in low line currents harmonic distortion and a power factor close to unity at the interface between the ac line and the rectifier. Various techniques are available for active current shaping, average current mode control, nonlinear control and one cycle control. Most of them are now supported by dedicated integrated circuits. Average-current-mode control is the regular control where the inductor current is forced to follow the input voltage. ...
