PROBLEM TO BE SOLVED: To provide a step up/down rectification circuit system having a wide output voltage range. ! SOLUTION: The step-up/down rectification circuit system has a step-up/down rectification circuit 50 which includes dual gate type switching elements 51, 52, 53, 54, 55, 56 and 65. The step-up/down rectification circuit system also includes: a first circuit 50a connected to the output end of an AC power source 1; a reactor 61 connected to the output end of the first circuit 50a; a second circuit 50b which includes single gated switching elements 57 and 58 and a dual gated switching element 59, and is connected the reactor 61; and a third circuit 50c connected to the second circuit 50b. !
