“…In the present study, we applied the system that transmitted the electric power and communication data based on Refs. [1,2] at the same time to the charge system of an EV, and we also did basic research that confirmed the charge to the battery. In this paper, we report on the excellent results obtained on our experiments with a non-contact transformer.…”

“…The geometry of the cores in Figure 2-14 is application specific. For example, the U-core [5,91], E-core [38,43,92] and H-core are common for monorail applications, while the flat bar and flat-E are typically used for Automatic Guided Vehicle (AGV) applications [93,94].…”

Inductive Power Transfer (IPT) systems can transfer electrical power from a power source to an electrical load wirelessly over relatively large air gaps. Such systems have a number of advantages as they are unaffected by dirt, ice, water and other chemicals, and are thereby environmentally inert and maintenance free. High-power applications of IPT systems include contactless charging of electric vehicles, materials handling systems and public transport systems, while typical low-power applications include wireless charging of biomedical implants and cellphones.High power Inductive Power Transfer (IPT) systems normally operate at power levels of 100kW or more. However, existing high power IPT power supplies are typically designed for specific power levels and, in low volume, are particularly expensive to make, due to the use of high power electronic components. This thesis presents an alternative method for realizing high power IPT power supplies by connecting multiple identical LCL-T based IPT power supplies in parallel across the track inductor. Both open-loop and closed-loop characteristics of the parallel topology are investigated.Firstly, I would like to thank my supervisors Prof. Grant Covic and Prof. John Boys for introducing me to the field of Inductive Power Transfer, and continuously supporting and guiding me throughout my study. Their deep insights and positive attitudes have always been very encouraging.I would also like to thank Dr. Andrew Green for his valuable guidance on the mathematical derivation of the small-signal model of the power supply. Without his help, Chapter 5 and Chapter 6 of this thesis might not be possible.
