Abstract:

The program objective was to develop a 270 vdc, 45 kw generator- controller system for a 9,000 to 18,000 rpm speed range, and to establish a data base sufficient to prove the feasibility of a 270 vdc electrical system as the primary aircraft electrical power. The 270 vdc system developed by AiResearch consists of a permanent-magnet generator with an internal cooling and lubricating system, a phase delay controlled thyristor rectifier, and a microprocessor-monitored protection unit. Functional requirements of the detail specification, including ripple and transient voltages, were successfully met. The feasibility and the advantages of the permanent-magnet generatorphase-delay rectifier-regulated system were demonstrated.
