dc.titleDesign and analysis of power factor correction zero-current switching switched-capacitor quasi-resonant convertersen_US
dcterms.abstractIn recent years, power quality is very popular in the world. Most power converters and equipment are developed to have power factor correction technology to improve their power factors. In the past research, switched-capacitor DC-DC converters were mainly used on low power applications for converting the DC voltage. They contain high switching harmonic current in the supply. In this thesis, a zero-current switched-capacitor quasi-resonant AC-DC converter with power factor correction (PFC) voltage to frequency controller is introduced. The PFC circuits provide zero-current-switching low current stress for switching components and improve high power factor over 0.9. The voltage to frequency controller for power factor correction is shown to be stable. The control algorithm, mathematical analysis, design equations, and the circuits are discussed in details. Experimental results using aforesaid approach are demonstrated in the thesis to verify the behaviour of the design.en_US
