Abstract

PURPOSE: To enable obtaining a stable output voltage even when a fluctuation of an input voltage and a load fluctuation are existing by providing an AC constant voltage device at an input side of a ferro resonance type constant voltage device indicating drooping characteristics.
CONSTITUTION: At a next stage of an AC constant voltage device 10 of an output being a constant voltage for fluctuations of an AC input such as one applied a magnetic amplifier, one applied a saturable reactor, one applied a phase controlling by a thyristor and one applied a ferro resonance, a ferro resonance type constant voltage device 11 operating under a range indicating drooping characteristics is connected. A constant voltage output of an AC constant voltage device 10 is established so as a ferro resonance type constant voltage device 11 to operate within a range indicating drooping characteristics. Then an AC constant current output is obtained at an output side of the ferro resonance type constant voltage device 11 and by rectifiing and smoothing this output with a rectifiing and smoothing circuit 12 a DC constant output is obtained
