Abstract
A resonant converter with power factor correction includes a power-obtaining circuit, an energy-storage element and an energy-transferred circuit. The power-obtaining circuit is used for receiving an input line voltage. The energy-storage element is coupled between the power-obtaining circuit and the energy-transferred circuit. The energy-transferred circuit is used for generating an output power. In a first time period, based on a first control signal, the energy-storage element and the power-obtaining circuit operate a soft switching so that the energy-storage element is charged to obtain the input line power and generate an energy-storage voltage. In a second time period, based on a second control signal, the energy-storage element and the energy-transferred circuit operate a soft switching so that the energy-storage element is discharged to make the energy-storage voltage converted into the output power.
