PURPOSE:To improve the efficiency of a DC/DC converter by removing a load sharing resistor connected with the output side of the converter. CONSTITUTION:A DC output from a DC power source 1 is output through a DC/ AC inverter 3, a transformer 4, a resonator 5 and a rectifier 6 from a smoothing circuit 7. This output current/voltage characteristic has an internal resistance intrinsic for a resonance type DC/DC converter. Accordingly, a uniform load share is performed for a load 10 by the intrinsic internal resistance, and a variation in a current for the variation in a load can be suppressed. The output current of a power supply is detected by current detectors 11-1, 11-2, 11-3, the detected erroneous voltages are respectively input to the error amplifiers 19-1, 19-2, 19-3 of controllers 16-1, 16-2, 16-3, compared with reference voltages 17 to produce output voltages V1, V2, V3, and the sum V0 of the voltages is input to the converter. |
