Medium-voltage motor drive systems, medium-voltage inverters, which have an input
voltage and an output voltage of 3.3 kV or 6.6 kV, are widely used in industry applications. In …

In this paper, a multiple wireless power transfer system for multiple gate driver supplies of a
medium voltage inverter is developed. The proposed isolation system achieves a galvanic …

This paper describes an ultracompact GaN 3× 3 matrix power converter with drive-by-
microwave (DBM) technology, which comprises a radio frequency (RF)-triggered GaN-gate …

One or more first switches coupled to one of a primary transformer winding and a secondary
transformer winding are controlled based on a first Switch control reference clock signal. A …

In recent years, the system voltage of a three-phase medium-voltage inverter for industrial
applications has risen to 3.3 kV or 6.6 kV (1)–(5). In a medium-voltage inverter, galvanic …

A low cost and compact isolated gate driver with Drive-by-Microwave technology is
developed, which consists of 2.4 GHz GaN/Si transmitter and receiver chips and the butterfly …

Digital isolators are widely used in isolated power converters for transmitting high-frequency
gating pulses. Conventional opto-isolators suffer from low reliability and poor delay …
