Title: Portable power supply device
Inventor: ASAI KOICHI
IPC: H02P9/30
Filed: 1997-10-06
Abstract: PROBLEM TO BE SOLVED: To maintain stable operation even in the case of a low power factor load, by comparing the waveform signal of a target frequency with the detection waveform signal of a single-phase AC output for detecting the power factor, and by providing a power factor detection means for reducing the output voltage of a variable control bridge circuit when the power factor is detected to be small. SOLUTION: Corresponding to a control function being calculated and outputted, an amplitude control circuit 12 generates a control signal for controlling the amplitude of a sinusoidal wave of 50 or 60 Hz being outputted from a sinusoidal oscillator 13, and a target wave output circuit 14 outputs a target wave corresponding to the control signal. In this case, a power factor detection circuit 19 compares the detection wave of single-phase AC output being outputted from an output voltage detection circuit 5 with a target wave being outputted from the target wave output circuit 14, detects a signal corresponding to the power factor, and adjusts an approximate effective value of an approximate effective value operation circuit 8 based on the detected signal.  In the case of a low factor load, the approximate effective value of the approximate effective value operation circuit 8 is reduced so that an output voltage is lowered.
