Gallium Nitride (GaN) based High-Power Multilevel H-Bridge Inverter for Wireless Power Transfer of Electric Vehicles

Abstract
This paper presents a design and implementation of a high-power Gallium
Nitride (GaN)-based multilevel Hbridge inverter to excite wireless charging
coils for the wireless power transfer of electric vehicles (EVs). Compared to
the traditional conductive charging, wireless charging technology offers a
safer and more convenient way to charge EVs. Due to the increasing demand of
fast charging, high-power inverters play a crucial role in exciting the
wireless charging coils within a wireless power transfer system. This paper
details the system specifications for the wireless charging of EVs, providing
theoretical analysis and a control strategy for the modular design of a 75-kW
3-level and 4-level Hbridge inverter. The goal is to deliver a low-distortion
excitation voltage to the wireless charging coils. LTspice simulation results,
including output voltage, Fast Fourier Transform (FFT) analysis for both
3-level and 4-level H-bridge inverters, are presented to validate the control
strategy and demonstrate the elimination of output harmonic components in the
modular design. A GaNbased inverter prototype was employed to deliver a 85-kHz
power to the wireless charging pads of the wireless power transfer system.
Experimental results at two different voltage and power levels, 100V-215W and
150V-489W, validate the successful performance of the GaN inverter in the
wireless charging system.
