PROBLEM TO BE SOLVED: To attain miniaturization and reduction of an I<2> R loss at a steady operation time, in a system link device interposed between power systems and between a power system and a consumer, connecting an AC terminal of a single phase rectifier circuit to each system, connecting a DC reactor between DC terminals to suppress an over current in case of trouble or failure, and to suppress an instantaneous voltage drop. SOLUTION: A DC reactor 24A, 24B, 24C of each phase A, B, C, as shown by DCL (DC reactor) 1, is integrally formed so as to generate mutual induction in a positive direction. In this way, of reactance required for the DC reactor 24A, 24B, 24C, by a mutual inductance amount, self inductance can be decreased. Accordingly, a winding capacitance is decreased, miniaturization and reduction of a cost can be attained, also an I<2> R loss can be also reduced. |
