Claim Text:
1. A converter circuit with power factor correction, configured for converting an alternative current (AC) input voltage into a direct current (DC) output voltage, comprising: an AC voltage source, configured for operatively outputting the AC input voltage and an AC input current; a bidirectional AC switch circuit, electronically connected to an end of the AC voltage source, the bidirectional AC switch circuit receiving a first control signal and a second control signal, and controlling the input current; a first un-bidirectional channel circuit, an end of the first un-bidirectional channel circuit electronically connecting to the bidirectional AC switch circuit; a first energy storing circuit, an end of the first energy storing circuit electronically connecting to the first un-bidirectional channel circuit; a second un-bidirectional channel circuit, an end of the second un-bidirectional channel circuit electronically connecting to another end of the first un-bidirectional channel circuit, and another end of the second un-bidirectional channel circuit electronically connecting to another end of the AC voltage source; a second energy storing circuit, an end of the second energy storing circuit electronically connecting to another end of the second un-bidirectional channel circuit, and another end of the second energy storing circuit electronically connecting to another end of the first energy storing circuit; an output circuit, an end of the output circuit electronically connecting to another end of the first un-bidirectional channel circuit, another end of the output circuit electronically connecting to another end of the first energy storing circuit, the output circuit operatively outputting the DC output voltage; wherein when the bidirectional AC switch circuit is on-state, at least one of the first energy storing circuit and the second energy storing circuit is charged by the AC input current and then energy is stored with magnetic flux form; when the bidirectional AC switch circuit is off-state, at least one of the first energy storing circuit and the second energy storing circuit releases the energy to the output circuit.
