Abstract : This invention relates to an apparatus for providing the voltage transformation functions of a conventional electrical power transformer. An AC input signal is chopped in a solid state switching converter at a frequency very much larger than the frequency of the input signal and then filtered to attenuate the high frequency component while passing the frequency of the AC input signal. The switching converter includes a pair of bidirectional solid state switches, an inductor and a capacitor connected in a buck converter, boost converter or buck-boost converter arrangement to provide a step up, step down, or step up/step down capability, respectively. A feedback signal modulates the duty cycle of the switching converter to provide automatic voltage regulation under varying loads and leading and lagging power factors. (Author)
