Abstract

Circuitry and methods for regulating alternating current regulation uses energy storage and release principles to boost or buck voltage to permit regulated ac operation with parallel and series bi-directional switch elements (12) and (13) operated at either variable duty cycles or frequencies to accommodate bipolar ac operation. Each bi-directional switch element may include a diode bridge (8) or (10) and directionally limited switches such as semiconductor switches. The system can be used to regulate ac even during sub-cycle dips, can be used to simulate controlled dips, can be used to correct power factor for loads, and can be applied in multiphase operations.
