Abstract

An entirely new type of AC voltage regulator is proposed by the use of our original variable capacitance device. This circuit theoretically makes no distortion of output voltage waveform, because only linear reactance devices are utilized in the power stage. Here, the variable capacitance device was employed as a linear capacitor to control output voltage. A boost-type DC-to-DC converter was used for a high-speed driver of this device
