<P>PROBLEM TO BE SOLVED: To provide a power conversion device capable of achieving a PFC action of an input current and AC-DC conversion with suppressed switching loss, using a magnetic energy regenerative switch having a soft switching function. <P>SOLUTION: The power conversion device 1 includes: an input section 100; a MERS 110; an output section 120; and a low-pass filter comprised of an inductor L and a capacitor C. The capacitor C is connected in parallel between the input section 100 and the MERS 110, and the inductor L is connected in series between the input section 100 and the MERS 110 to achieve a PFC action of an input current and to suppress loss with simple control without necessity of input sensor. <P>COPYRIGHT: (C)2012,JPO&INPIT |
