Abstract
A voltage amplitude adjuster including semiconductor switches for power conversion, an AC chopper for converting an input AC voltage to an AC voltage of the same phase and different amplitude relative to the input AC voltage, and a smoothing AC filter for providing a clear signal to a primary winding of a transformer. Further, by providing a wattmeter, the saved power can be displayed.
