Research Projects

The proposal is to design, implement and analyze a Wireless- Battery Charging System in motion of 1.2 kW, 165Ah rating light-duty electric vehicle. In this proposed system, the transmitter block of the Resonant Inductive Power Transfer (RIPT) system is built on roadway transportation. The resonant inductive power transfer system is the most fashionable current WPT technology and uses two or more tuned resonant tanks operating at the resonance frequency. The transmitters are placed on a 5m track (15 spiral circular coils each 32 cm diameter) such that the laboratory model electric vehicle can move over the transmitter coils to receive the power in motion. The transmitter block consists of an inverter, rectifier, and high-frequency coil. The power supply is given from a 230V AC supply. 230V AC Supply is rectified by the rectifier circuit. The rectified current is fed into an inverter circuit the input supply is switched by the FPGA controller. The output of the inverter supplies high-frequency voltage to the transmitter coil. The transmitter coil produces the high-frequency magnetic flux. The receiver block has a high frequency receiving coil which receives the power from the transmitter coil and is mounted on the bottom of the electric vehicle. The induced voltage in the receiver coil is first rectified by using a diode bridge rectifier. The rectified voltage is supplied to DC-DC boost converter. The output voltage of the boost converter is regulated using an FPGA controller for charging the EV battery at a constant voltage. The overall performance of the electric vehicle battery charging system will be carried out in motion with circular structure coupled coils.
