Design and construction of an H-bridge inverter used in wireless power transfer

This paper presents the H-bridge inverter prototype design and construction used in wireless power transfer, designed to operate at high frequencies. The block diagram of the electronic subassemblies of the inverter, hex inverter with Schmitt-Trigger, drivers, and power stage, is presented, from the design step to the final product. Throughout the paper, aspects related to the functioning, testing, and discrete electronic components parameterization and also aspects to improve the output inverter voltage waveform are presented.
