Abstract

An AC-DC power conversion system (400) provides extended voltage gain characteristic by virtue of controlling a duty cycle of operation associated with the desired input-to-output gain. The AC-DC power conversion system (400) includes an AC-stage, first and second inductors (L<1>, L<2>), first and second voltage-doubler stages (401a, 401b), a totem-pole rectifier stage (402), and a DC-stage (403) coupled across the totem-pole rectifier stage (402). Each voltage-doubler stage (401a, 401b) includes a first terminal, a second terminal, and a third terminal, wherein a first terminal of the AC-stage is coupled by the first inductor (L<1>) to the first terminal of each voltage-doubler stage (401a, 401b) and by the second inductor (L<2>) to the third terminal of each voltage-doubler stage (401a, 401b). The totem-pole rectifier stage (402) includes first and second terminals coupled, respectively, to the second terminal of the first voltage-doubler stage (401a) and the second terminal of the second voltage-doubler stage (401b).
