Researchers at the University of Hong Kong and the Centre for Advanced Semiconductors and Integrated Circuits have unveiled the world’s first megawatt ultra-wide-bandgap semiconductor module. Led by Professor Yuhao Zhang, this team has successfully engineered a gallium oxide power module capable of handling unprecedented power conversion levels.
This groundbreaking multi-chip power module demonstrated repetitive switching at 1,000 volts and 1,000 amperes, marking a massive milestone for high-voltage electronics. Enthusiasts tracking recent optics news and semiconductor advancements will recognize this as a pivotal moment for modern engineering.
Overcoming Material Limitations in Gallium Oxide
Although gallium oxide possesses exceptional material properties for high-voltage electronics, it has historically faced severe limitations regarding poor heat conduction and packaging difficulties. Researchers had to innovate past these inherent physical barriers to make megawatt-scale operation a reality in the laboratory.
To conquer these engineering obstacles, the team utilized a joint device-package co-design approach to simultaneously manage electric fields, thermal flow, and mechanical stress. They implemented a novel junction-side cooling architecture alongside a high-permittivity insulating layer to drastically improve heat dissipation and voltage handling.
Achieving Exceptional Performance Metrics
A single packaged device successfully conducted 234 amperes at 1,000 volts while remaining entirely functional at extreme junction temperatures exceeding 250 degrees Celsius. By integrating six of these robust devices together, the researchers created a module capable of repetitive switching at a peak power level of one megawatt.
