Design of contactless capacitive power transfer systems for battery charging applications

The main aim of the thesis, is to develop a high power system for small and large air-gaps applications, concurrently possessing high efficiency. To tackle the problems stated, two modified converters where proposed. The first proposed topology could yield higher power transfer for small air-gap applications. The topology proposed exhibits better efficiency and has several advantages compared to the existing topologies for small air gap applications. The second topology is called the Dual LC topology, which reduces the voltage stress across the capacitive interface enabling the CPT system to be used for large air gap applications. The Dual LC topology showcases excellent efficiency for variation in air-gap and under misalignment conditions. In final section of this thesis, the CPT system is extended to charging an industrial electric vehicle (IEV). As the requirement of charging an IEV varies depending on its battery pack. The power flow and control for the CPT systems is implemented.
