To provide an electric power conversion system which reduces capacitance of a floating capacitor and suppresses heat generation due to a charge/discharge current of substrate wiring.SOLUTION: An electric power conversion system comprises a switching circuit, an isolation transformer, a rectifier circuit, and a multilayer wiring board. Output side wiring of the switching circuit is connected with primary side wiring of a first transformer or primary side wiring of a second transformer. Input side wiring of the rectifier circuit is connected with secondary side wiring of the first transformer or secondary side wiring of the second transformer. At least one set of pair wiring of four sets of pair wirings i.e., input side wiring of the switching circuit and output side wiring of the switching circuit, the primary side wiring of the first transformer and the primary side wiring of the second transformer, the secondary side wiring of the first transformer and the secondary side wiring of the second transformer, and the input side wiring of the rectifier circuit and output side wiring of the rectifier circuit is formed on a wiring layer of the multilayer wiring board. The wiring layer on which the pair wiring is formed is laminated on a shield conductor wiring layer via an insulator layer.SELECTED DRAWING: Figure 1 【課題】電力変換装置において、浮遊コンデンサの容量を削減し、充放電電流による基板配線での発熱を抑える。【解決手段】スイッチング回路と、絶縁トランスと、整流回路と、多層配線基板と、を備え、スイッチング回路出力側配線は、第１のトランス１次側配線または第２のトランス１次側配線と接続されており、整流回路入力側配線は、第１のトランス２次側配線または第２のトランス２次側配線と接続されており、多層配線基板の配線層には、スイッチング回路入力側配線とスイッチング回路出力側配線、第１のトランス１次側配線と第２のトランス１次側配線、第１のトランス２次側配線と第２のトランス２次側配線、および、整流回路入力側配線と整流回路出力側配線、の４組のペア配線のうち、少なくとも１組のペア配線が形成されており、このペア配線が形成されている配線層は、絶縁層を介して、シールド導体配線層と積層されている電力変換装置。【選択図】図１
