PROBLEM TO BE SOLVED: To achieve a simple and high-efficiency isolated power conversion circuit.SOLUTION: A power conversion circuit includes: a first capacitor provided at an input side of power to be converted; a first transformer having a primary-side circuit connected to the first capacitor; and a switching circuit blocking a conducting path at the primary side of the first transformer. The switching circuit has four links each having a switching element and a diode, and forms a parallel circuit branching from a first node passing through the primary-side circuit of the first transformer. The first link and the second link of the four links branch from the first node, the third link is connected in series to the first link, the fourth link is connected in series to the second link, and the third link and the fourth link are joined together at a second node passing through the first capacitor. Moreover, a second capacitor is provided between the connection point between the first link and the third link and the connection point between the second link and the fourth link. |
