Variable Turn Ratio Current-Source Charge Pump Power Factor Correction Converter With High Power Factor and Wide Input Voltage Range

Power factor correction (PFC) is widely used in ac-dc converters to improve power quality. The current-source charge pump (CS-CP) PFC converter has the advantages of simple structure, easy control, and low cost, but it can only obtain a high power factor (PF) over a narrow input range. The operation...
