Abstract
Abstract AN INVERTER DEVICE INCLUDES A PLURALITY OF THYRISTOR BRIDGES RESPECTIVELY CONNECTED TO A CORRESPONDING LOAD FOR ENABLING THE SEPARATE ENERGIZATION THEREOF. AN ESSENTIALLY SINGLE COMMUTATING CIRCUIT DEVICE IS PROVIDED IN COMMON WITH ALL OF THE BRIDGES FOR ENABLING THYRISTORS THEREIN TO BE SIMULTANEOUSLY TURNED ON AND OFF. A COMMON FREQUENCY SOURCE IS PROVIDED FOR SUPPLYING SYNCHRONIZED GATING PULSES TO THE COMMON COMMUTATING CIRCUIT AS WELL AS TO THE THYRISTOR BRIDGES. THE THYRISTOR BRIDGES RESPECTIVELY RECEIVE THE GATING PULSES FROM THE FREQUENCY SOURCE THROUGH SEPARATE GATE CONTROLS. IN THIS MANNER, IT IS POSSIBLE TO SELECTIVELY ENERGIZE A PLURALITY OF LOADS FROM AN ESSENTIALLY SINGLE INVERTER DEVICE.
