TWO WIRE HIGH FREQUENCY POWER DISTRIBUTION AND COMMUNICATION SYSTEM

摘要

Interconnections and harnesses add considerable complexity and weight to modem complex industrial electronic systems. A system using only a single two wire interconnection between different units and featuring transformer isolation to eliminate earth loops and achieve easy EMC is proposed. A high frequency carrier is added to the output of a switchmode inverter. An inverter topology is proposed which is designed to contain the high frequency content of the power output voltage waveform in order to avoid pollution of the information frequency band. A prototype system is described and experimental results are given.
