A Totem-pole power factor corrector receives an input power source (Vin) and convert the input power source (Vin) into an output power source (Vo). The Totem-pole power factor corrector includes an input inductor (L, Lboost, nL), a fast-switching switch leg (11), a slow-switching switch leg (12), a resonant tank (13), and an output capacitor (Co). The fast-switching switch leg (11) includes a fast-switching upper switch (S2, nS2) and a fast-switching lower switch (S1, nS1), and the fast-switching upper switch (S2, nS2) and the fast-switching lower switch (S1, nS1) are commonly coupled at a first middle node (N1). The slow-switching switch leg (12) is coupled in parallel to the fast-switching switch leg (11), and the slow-switching switch leg (12) includes a slow-switching upper and a slow-switching lower switch (Mi). The resonant tank (13) includes a resonant inductor (Lr, nLr) and at least one resonant capacitor (Cr, nCr). A first end of the resonant inductor (Lr, nLr) is coupled to the first middle node (N1), and a second end of the resonant inductor (Lr, nLr) is coupled to the at least one capacitor.
