Resonant power factor correction circuits with resonant capacitor-voltage and inductor-current-programmed controls

It is shown that, by using the control techniques proposed, one can use current driven resonant power converter topologies in designing resonant power factor correction circuits (RPFCCs). Based on the fact that the energy stored in the resonant tank circuit can be programmable, two types of control techniques that allow for fast output regulation are reported. These techniques are known as resonant tank capacitor-voltage-programmed control and inductor-current-programmed control. A design example based on the resonant capacitor-voltage-programmed control technique and computer simulations is given
