Claim 13:
14. A method comprising:
controlling a dual gate metal oxide semiconductor field effect transistor (MOSFET) device formed in a semiconductor material, the dual gate MOSFET device including a first MOSFET formed in the semiconductor material, and a second MOSFET formed in the semiconductor material, wherein the first MOSFET and the second MOSFET are arranged in parallel in the semiconductor material, wherein the first MOSFET and the second MOSFET include a common drain node and a common source node, and wherein the first MOSFET and the second MOSFET define different transfer characteristics, wherein controlling the dual gate MOSFET includes:
controlling the first MOSFET according to a pre-charging routine associated with a direct current (DC) link capacitor associated with an electric vehicle or another high-voltage operated system, wherein the pre-charging routine to pre-charge the DC link capacitor includes controlling the first MOSFET to operate in a linear mode of operation in a current-limited manner so as to create increasing energy delivered to the DC link capacitor over time during the pre-charging routine; and
following the pre-charging routine, controlling the second MOSFET to turn on the second MOSFET to operate in a non-linear mode of operation and define a highly conductive current path in the presence of a pre-charge on the DC link capacitor.
