Energized by the prospect of decluttering the charging infrastructure by severing the bulky power cords used to charge an Electric Vehicle (EV), an innovative technique to wirelessly charge an EV battery known as Inductive Power Transfer (IPT) has garnered widespread acceptance. This thesis introduces the design of an integrated stationary IPT system with an optimized power control algorithm and efficiency maximization to transfer power from a transmitter pad positioned on the ground and the receiver pad embedded under the chassis of an EV. Magnetic analysis for the charging coil architecture is facilitated via simulations in Ansys Maxwell. The power electronics design focuses on implementation of an H-bridge converter incorporating Series-Series (SS) compensation topology to utilize a novel control algorithm to prioritize battery charging operation. The system is validated through a simulation model in PSIM and a hardware-in-the-loop simulation in Typhoon HIL before hardware implementation and testing of the developed prototype.
