  • Automatic and user initiated isolation testing for automotive alternating current power systems
    Patent number: 11498499
    Abstract: A vehicle inverter is arranged to transform direct current power from a power supply to alternating current power for an outlet. The inverter includes a transformer electrically connected between the power supply and outlet, a resistive element that can be selectively electrically connected in parallel with the transformer via a multiway switch to establish a direct electrical connection between the power supply and outlet, and a controller that selectively commands the multiway switch to close according to values indicative of resistance between the power supply and outlet before and after the multiway switch is closed.
