Abstract :
A novel high frequency hybrid power distribution system for telecommunication applications is presented. The proposed hybrid system combines the advantages of both the sinusoidal voltage and current types of high frequency distribution systems and it has advantages such as connectorless power transfer, fuseless protection, sinusoidal voltage and current distribution and, high overall system efficiency. The different operating modes of the proposed power distribution system are described in detail and performance characteristics are presented. Finally experimental results are given to validate the concepts developed and to demonstrate the system performance
