Abstract

PURPOSE: To obtain an AC power supply which can broaden the control width (dynamic range) by increasing the ratio of positive and negative wave heights under the control of the switching mode to stabilize both the positive and negative waves independently.
CONSTITUTION: Switching transistors 14, 14' for operating in push-pull manner at the primary side of a transformer 18 are connected to apply alternatively two-phase pulses thereto to thereby obtain an AC at the secondary side of the transformer 18. There are provided pulse width modulators 12, 12' triggered by an oscillator 11, a flip-flop 15 for dividing the frequency oscillated at the oscillator 11 in synchronization therewith to half, comparison amplifiers 17, 17' for amplifying the difference between the standard voltage and the signal voltage, a detector 16 for detecting independently the positive and negative signals of the composite voltage and current signal or vice versa, and gate circuits 13, 13'. Accordingly, it can independently stabilize both the positive and negative signals to increase the positive and negative wave height ratio to thereby obtain an AC power supply which can broaden the control width.
