  • Patent number: 11932123
    Abstract: Discharge systems for electric vehicles and electric vehicles having discharge systems. In one implementation, a discharge system for an electric vehicle includes a step-down power converter configured to step down an input voltage to an output voltage; discharge circuitry coupled to the output of the step-down power converter, wherein the discharge circuitry is reversibly driveable to load the step-down power converter; an input component configured to receive input that originated from a human user or a sensor of the electric vehicle, wherein the input indicates that the electric vehicle is to shutdown; and discharge drive circuitry configured to drive the discharge circuitry to load the step-down power converter in response to the indication that the electric vehicle is to shutdown.

  • Publication number: 20220258610
    Abstract: An electric drive system for a vehicle includes an inverter having at least one phase leg, wherein a first of the phase legs includes a first power switch; an internal voltage supply configured to generate an internal supply voltage regulated with respect to a voltage on a rail and a second voltage, wherein the internal voltage supply is configured to reduce a voltage difference between the internal supply voltage and the second voltage in response to a signal indicating a shut-down or a fault; and a gate drive channel configured to drive the first power switch into conductance by applying the voltage difference between the internal supply voltage and the second voltage between a control terminal and a main terminal of the power switch, gate drive channel configured to continue the driving of the first power switch for a time duration after the signal indicating the shut-down or the fault.

  • Patent number: 10461733
    Abstract: In one aspect, a device includes a first power switch having a first gate, a second power switch paralleled with the first power switch and having a second gate, a gate driver to output a gate drive signal to drive both the first gate and the second gate, a first conduction path to couple the gate drive signal to the first gate, a second conduction path to couple the gate drive signal to the second gate, and a distribution choke to distribute the gate drive signal to the first and second power switches. The distribution choke has a first winding disposed in the first conduction path and a second winding disposed in the second conduction path. The distribution choke is coupled in a differential mode.
