This article gives an overview of the analysis and modelling for 22 kW wireless power transfer (WPT) for Light Duty (250V traction battery) and Heavy Duty (700V) electric vehicles (EV). The system under investigation is the series/series (SS) WPT compensation topology, for which an iterative design approach is considered to select the suitable final system parameters. A simulation study is performed for a selected WPT design for different power electronics topologies, differing in the converter type at secondary side and EV battery voltage. The study focusses on the design and system evaluation of two proposed WPT vehicle architectures and their control for the different secondary systems that are supplied by the same and identically controlled grid system, to achieve interoperable WPT systems. Stable control at high efficiency (>90%) is achieved for both studied topologies, one with a boost DC/DC converter at secondary side and charging a 700V battery, the other with buck DC/DC converter to 250V.
