PURPOSE:To attain various control functions in time division based o the controlled variables by sampling an input signal in high speed and detecting a desired control variable from the obtained sample value. CONSTITUTION:A signal converting section 22 converts a signal such as generator voltage or current to a prescribed level, a basic wave component is extracted from an AC control signal, and ripple is eliminated from the DC signal (e.g., voltage/current signal). Further, a digital automatic voltage adjuster 21 consists of a sample holder 24, an A/D converter 25, a digital control operating section 26, a digital output circuit 27 and a pulse phase shifter 28. |
