Receiver-Side Power Control of a 200-kW Three-Phase DWPT System for Heavy-Duty Vehicles

A 200-kW DC-DC converter has been designed to enable receiver-side power control in a heavy-duty electric vehicle equipped with wireless power transfer technology. The converter employs an interleaved, non-inverting cascaded buck-boost converter topology to meet high power demands and ensure optimal performance during transmitter pad-to-pad transitions and vehicle misalignment. Power delivery is managed through a cascaded control strategy combining an inner inductor-current controller with an outer output-current controller. This is integrated with a Class-8 electric vehicle to be tested on an electrified roadway test bed currently under development along US-52/231 in Indiana, USA. Comprehensive simulation and hardware results are provided to validate its operation.
