Abstract
Power electronics circuitry includes a pair of parallel switching elements. Each of the switching elements includes two power terminals, two control terminals, and an additional terminal. Corresponding ones of the two power terminals from each of the pair are connected via respective first and second power paths. Corresponding ones of the two control terminals from each of the pair are connected via respective first and second control paths. The additional terminals are connected via an additional path. The circuitry also includes a gate driver tapping the first and second control paths, and a magnet surrounding the additional terminals to couple inductance of the additional path.
