Abstract
An electronics unit for an electrical device, in particular for a motor-operated electrical device, includes a printed circuit board populated, in particular on one side, and having a plurality of power transistors for actuating a multiphase load, in particular a multiphase electric motor, of the electrical device. Each phase of the load is assigned at least one power transistor. A first electrical damping element for damping transients caused by switching processes of the power transistors is connected in parallel with at least one of the power transistors of a first phase with a highest leakage inductance. No electrical damping element acting in this manner is provided for at least one of the other phases of the load, in particular for the phase with a lowest leakage inductance.
