Architecture and design of an inductive contactless energy transfer system with two mobile loads for residential applications

Inductive contactless energy transfer systems with multiple mobile loads are very complex systems. Main challenges of these systems are to propose a suitable architecture and to design their power components. These challenges are particularly more noticeable in residential areas where various types of consumers (loads) are expected. This paper introduces a new architecture and design guidelines for a high-frequency resonant transformer operating with frequency modulation. The design process includes the effects of 1) the resonant frequency, 2) the magnetizing inductance, and 3) the characteristic impedance. The excellent performance of the designed system is validated by simulation results.
