Abstract

PURPOSE: To enable to suppress the variance in the load voltage with good response, even if the smoothing filter is constituted with LC filter, by extracting the increment or decrement of the load voltage together with the voltage dividing the load voltage, and taking the variance as control input.
CONSTITUTION: If the load 30 is suddenly greater and the voltage between the load terminals 31 and 32 is suddenly decreased, the rapid decrement of the terminal voltage is fed to the input terminals 41 of the control circuit 40 with the capacitor C0. The control signal rapidly increasing the DC output of the DC power circuit 10 of the circuit 40 is produced to increase the load voltage, allowing to suppress the transient variance of the load voltage. Further, if the load is slowly changed, the value dividing the load terminal voltage with resistances R1, R2 is fed to the terminal 41 and the circuit 40 controls so that the DC voltage produced at the circuit 10 can be kept constant. Further, even if the LC filter 20 is constituted with the multistage LC filter, the response can be improved.
