Abstract
A power relay assembly is provided and includes a first relay that is connected to a positive end of a battery and a second relay that is connected to a negative end of the battery and connected to the first relay via a DC capacitor. A first Field Effect Transistor (FET) is connected in parallel with the first relay and a second FET is connected in parallel with the first relay and connected in series with the first FET. A voltage control circuit is configured to adjust a voltage of the first FET with a first voltage or adjust a voltage of the first FET with a second voltage lower than the magnitude of the first voltage.
