Parallel coupled static inverters

摘要: An alternating current power-supply system is disclosed in which plural static inverter modules are coupled parallel to share a common load. Each module held phase synchronization with reference by circuitry generates signal within logic of the and compares generated that so as vary frequency until lock achieved. The output amplitude each normally regulated voltage makes appropriate adjustments based on comparison render equal reference. Additional regulation provided determines average various voltages corrects any having an differs from determined average.
