Brushless variable speed constant frequency (VSCF) electric power generation may be obtained using cascaded symmetrically wound machines. The feasibility of using these machines as the basis for a stand-alone aircraft generator system was investigated by the USAF Aero Propulsion Laboratory. The results of that investigation were presented at NAECON 1983. The concept is attractive as the system operates without hydraulics and employs a solid state power converter which operates at a fraction of the system output power and frequency. These factors combine to offer a system of relatively low complexity with the potential for high-reliability operation. This paper reviews the steady state results of an experimental, cascaded doubly fed (CDF) VSCF generator system. In addition, this paper will discuss the operation of the microprocessor-controlled inverter section of the solid state power converter.
