摘要： A solid-state switch includes a plurality of transistors connected in parallel and a plurality of fuses. Each fuse is connected in series with a separate one of the plurality of transistors. A combination of current ratings of the plurality of fuses is greater than a load current of a load connected to the plurality of transistors and the plurality of fuses, and a current rating of each separate fuse of the plurality of fuses is less than the load current.

摘要： A method of performing active vibration damping in a front end accessory drive (FEAD) system of an automobile using an alternator of the FEAD system and an alternator are described. The method includes determining a resonance to be counteracted, determining a counteracting forcing function to counteract the resonance, and determining a duty cycle change to apply to a field voltage to obtain an output voltage with the counteracting forcing function, wherein the field voltage results in a field current supplied to a rotor that causes a stator to generate the output voltage. The method also includes implementing the duty cycle change for a period of time.
