A generalized method for switched-capacitor resonant converter for use in power factor correction is proposed. Using the techniques, the voltage conversion can be generated into step-up, step-down and inverting. The requirement of the inductance in the circuit is minimal. The quality of the power factor improvement is substantial. The method used in the converter includes the frequency modulation and lifting techniques. The power factor improvement is significant and the circuit concept is simple. Mathematical analysis and experimental confirmation have been presented to demonstrate the novel idea.
