Abstract
An AC power supply apparatus for obtaining sampled data required for the FFT (Fast Fourier Transformation) by an A/D converter. Since a clock pulse train for forming an output voltage (power supply output) is used as sample clock pulses, sampled data associated with exactly one period can be obtained. This eliminates the need for the window processing. This makes it possible to provide a low cost, error-free apparatus.
