ABSTRACT:
A variable speed, constant frequency generating system has a neutral forming autotransformer connected between a variable speed generator and an AC to AC converter. The converter includes a three-phase full wave-rectifier with positive and negative rails connecting the rectifiers with a DC to AC inverter. Each turn of the transformer windings has at least one surface exposed to air for cooling.
