とを特徴とする出力安定化装置。 a conversion circuit that converts the input signal to a predetermined level;
An output level detection circuit detects the power supply output level output from this conversion circuit, and an output error is obtained by comparing the detection level of this output level detection circuit with a reference level, and the output of the conversion circuit is determined according to this output error. stabilizing means for stabilizing the power supply output level by variably controlling a value; and stabilizing means for stabilizing the power supply output level by selectively switching the reference level to the first and second values; The output stabilizing power supply has a switching setting means for switching and setting the output, and the output stabilizing power supply has means for changing the set value of the gain or phase compensation time constant of the stabilizing means when the output error exceeds a specified level. Features an output stabilization device.
