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.
