A hybrid electrical power system for aircraft application
1971 IEEE Power Electronics Specialists Conference, 1971The trend of commercial aircraft today is toward larger size and more electric service power. As the aircraft becomes larger and environmental conditions become more severe, stringent design requirements such as a high degree of reliability, minimum operating cost, and minimum weight are imposed on the aircraft electrical power system. In reviewing the
