摘要：

Previous entertainment systems for aircraft passengers have consisted of a single video program shown at the front of the cabin and multiple audio channels available in the armrest. A recently developed entertainment system places small video entertainment sets at every seat for use by each passenger. Each set in the system must be provided with audio and video programming and the eleetrical power necessary to operate the set. Distribution of programming and power to the sets with a connector for each set would cause reliability and maintenance problems and hinder timely cabin reconfiguration. The entertainment sets can receive audio and video signals through radio-frequency transmission, but distributing power to the sets without using connectors requires a novel approach. Analysis, design, and construction of a prototype connectorless power supply is described that inductively couples power to the entertainment sets across an air gap. An equivalent-circuit model of the connectorless power supply is developed, and laboratory measurements performed on the prototype power supply are discussed. The prototype unit is shown to be a practical implementation that meets all design requirements.
