Use of cycloconverters and variable speed alternators as engine starters

Abstract

IN VARIABLE SPEED constant frequency (VSCF) generating systems for aircraft, the variable frequency generator, usually six phase, is directly coupled to a main propulsion engine. The output of this generator is converted to three phase constant frequency, usually 400Hz, for general aircraft use by a cycloconverter using thyristors as switching devices.
