An electrical power system includes an electrical machine having one or more windings and an AC-DC power electronics converter including a commutation cell having a power circuit and a gate driver circuit. The power circuit includes a plurality of power semiconductor switching elements and a capacitor. The gate driver circuit is electrically connected to and configured to provide switching signals to a gate terminal of each power semiconductor switching element. A peak rated power output of the electrical machine and the AC-DC power electronics converter is greater than 25 kW, a maximum efficiency of the AC-DC power electronics converter is greater than 97%, and a value of parameter β is greater than or equal to 0.3 PV/s2, where β is a product of a maximum switching frequency of the switching signals and a maximum rate of change of a source-drain voltage of the plurality of power semiconductor switching elements.
