From solar and wind to energy storage: Trends and solutions
Despite their varied applications, solar inverters, wind turbine converters and ESS solutions have a lot in common. Each typically operates up to the voltage and current extremes of existing silicon switch technology, and each benefits from the efficiency improvements wide-bandgap SiC switches and diodes are offering.
Modern clamping systems for power semiconductor tests
Power semiconductor devices have many parameters and characteristics that must be measured using specialized equipment. Design of such equipment must account for many factors such as reliability, flexibility, ergonomics, and attention to overall aesthetics. This article describes the steps of development and research carried out to design a clamping system for disc semiconductors and analyzes the encountered issues. A number of technical solution...
