摘要： PURPOSE:To eliminate a saturation phenomenon in the control for constant power and constant voltage controller, by switching a gain of each detector for the constant power and consant voltage control, when operated a start or stop partially for AC-DC converter. CONSTITUTION:At a time of start-stop partially operated for AC-DC converter in AC-DC converters CON1, CON2, that are controlled by a constant power controller CONT1 and a constant voltage controller CONT2, in the constant power controller CONT1 the constant power control is once switched to a constant current control ACR, during the period of which the gain of an amplifier Amp is made to be switched by the switching signal from an AND circuit AND1. And in the constant voltage controller CONT2, the switching of the gain of the amplifier Amp and the momentary changing of the DC voltage set value are simultaneously operated. Consequently, a saturation phenomenon can be eliminated in the control for the constant power and constant voltage controller, thus capable of smoothly operating the DC power transmission.
