Abstract
A Totem-pole power factor corrector receives an input power source and convert the input power source into an output power source. The Totem-pole power factor corrector includes an input inductor, a fast-switching switch leg, a slow-switching switch leg, a resonant tank, and an output capacitor. The fast-switching switch leg includes a fast-switching upper switch and a fast-switching lower switch, and the fast-switching upper switch and the fast-switching lower switch are commonly coupled at a first middle node. The slow-switching switch leg is coupled in parallel to the fast-switching switch leg, and the slow-switching switch leg includes a slow-switching upper and a slow-switching lower switch. The resonant tank includes a resonant inductor and at least one resonant capacitor. A first end of the resonant inductor is coupled to the first middle node, and a second end of the resonant inductor is coupled to the at least one capacitor.
