Abstract

PURPOSE:To control a preferable DC output voltage by providing a circuit for detecting the phase voltages of a 3-phase AC power source from AC power source terminals and obtaining a signal for controlling the phase of a rectifying circuit with the phase voltage. CONSTITUTION:The output terminal of an AC power source 1 is connected to 3-phase equilibrium loads 18a, 18b, 18c made of resistors, phase voltages are detected across the loads 18a, 18b, 18c, and signals for controlling the phases of rectifying circuits 2a, 2b, 3c, 3a, 3b, 3c are obtained from the phase voltages. Thus, a preferable DC output voltage can be obtained even if no reactor is inserted to the output line of the phase control rectifying circuit.
