Abstract: This webinar is presented by PELS Young Professionals (YP) To establish an efficient inductive power transfer (IPT) mechanism for electric vehicles (EVs) it is necessary that a system with an optimized power control and efficiency is established. As the equivalent resistance of the on-board battery charger continuously fluctuates during operation, a battery charging algorithm based on an improvised continuous current (CC) – constant voltage (CV) methodology is proposed. A novel design of an integrated stationary IPT system to inductively transfer power from a transmitter pad positioned on the ground and a receiver pad embedded under the chassis of an EV prototype is introduced. An innovative feature of this design is the implementation of a magnetic switch sensor that is incorporated into both the transmitting and receiving wireless charging circuitry to ensure optimum alignment for IPT. The power electronics design focuses on the implementation of an H-bridge converter incorporating series–series (SS) compensation topology to use an innovative control algorithm to prioritize battery charging operations. The system is validated through a simulation model in PSIM and a hardware-in-the-loop (HIL) simulation in Typhoon before hardware implementation and testing of the developed prototype.
