MAGNETIC FIELD COMMUNICATION APPARATUS FOR ONLINE ELECTRIC VEHICLE USING ELECTROMAGNETIC INDUCTION

摘要

PURPOSE: A magnetic field communication apparatus of an on-line electric vehicle using electromagnetic induction is provided to communicates between an inverter and an on-line electric vehicle by transmitting energy to a secondary resonance load circuit unit from a first conductive line with an electromagnetic induction. CONSTITUTION: A first electronic induction circuit unit is installed on the lower side of a vehicle which passes on a power rail. A secondary load resonance circuit unit is laid under a road. A DC voltage of an input terminal(10) is converted into an AC voltage in a primary resonance circuit unit(30) through a rectifier. The converted AC voltage is transmitted to a secondary coil of the load side resonance circuit. A photocoupler outputs a DC signal converted by the rectifier.
