PROBLEM TO BE SOLVED: To equalize the use rate of R phase and T phase power supplies, by providing specified numbers of cores close to power supplies, and by winding the lines of R phase and T phase on one core, and by winding lines that connect the R phase line to the T phase line and are connected to an N phase line on the other core. SOLUTION: Two pieces of cores CRA, CRB are provided close to power supplies ER, ET. Coils CLAR, CLAT are formed by winding a line between R1 and 1 of R phase and a line between T1 and 3 of T phase on one core CRA. Coils CLBR, CLBT are formed by winding lines that connect the R phase line to the T phase one and are connected to an N phase line on the other core between the R phase line 1 and N phase line 2, and between the T phase line 3 and N phase lines 2 and 3. In this power supply balancer circuit BL of this constitution, IR1=IT1 and IN1=IT1-IR=0 are maintained. As a result, two units of power supplies ER, ET can be used with the same use rate. |
