PROBLEM TO BE SOLVED: To obtain the precise AC power approximated to a sine wave by accurately setting the cycle of an AC power. SOLUTION: A kick signal generator 10 counts the number of clocks of period data, and outputs a kick signal at each period data. PWM units 11- U, 11- V, 11- W generate control signals from the period data, and output control signals to drivers 12- U, 12- V, 12- W at each time of outputting the kick signal. The drivers 12- U, 12- V, 12- W generate AC power from the control signal. |
