Title: Ac power regulator
Inventor: MANABE KAZUHISA
IPC: G05F1/45
Filed: 1997-10-31
Abstract: PROBLEM TO BE SOLVED: To provide an AC power regulator, with which more stabilized power can be supplied to the load of a device, by suppressing the fluctuation in the output voltage of the AC power regulator corresponding to a rapid change in the voltage of an AC power source through a differentiation circuit. SOLUTION: A control circuit 40 turns the output of a differentiation circuit 42 into (+) polarity when the voltage of an AC power source 1 is rapidly lowered, and turns it into (-) polarity when the voltage of the AC power source 1 is rapidly increased. Then, an addition computing element 43 adds the output of the differentiation circuit 42 and the output of a voltage regulator 23 for performing regulating operation based on the deviation of an output voltage setting value and an output voltage detecting value. Thus, the rapid change in the voltage of the AC power source 1 is compensated and based on the setting value of a voltage setter 21, the almost fixed voltage is supplied to a load 2.  Therefore, even when the AC power source is rapidly changed or hit failure occurs, the fluctuation in the output voltage of such an AC power regulator 30 is suppressed and as a result, the stabilized power can be supplied to the load 2.
