    Abstract: A gate driver controller, inverter circuit apparatus, and associated discharge method for electric vehicles are disclosed. An example gate driver controller includes a mode determiner to set a mode of operation of the gate driver. The example device includes a gate driver control to control the gate driver to set the gate driver to: a) on, b) off, or c) generate a pulse width modulation signal. When in a first operating mode and set to on, stored energy is to be transferred from a capacitor to a motor winding inductor via a power transistor activated by the gate driver to dissipate a first portion of the stored energy. When in a second operating mode, a second portion of the stored energy is to be transferred from the motor winding inductor to the power transistor to dissipate the second portion of the stored energy.

    Abstract: A system comprises a gate driver that is configured to couple to a transistor disposed in a transistor module via a first pin. The gate driver comprises a duty cycle measurement circuit having a first input terminal and a first output terminal, the first input terminal coupled to a second pin via an isolator. The duty cycle measurement circuit comprises a flip-flop, a counter, a shift register, and a comparator. The system comprises an analog to digital converter circuit having a second input terminal, a second output terminal, and a reference terminal, the second input terminal coupled to a third pin configured to couple to a temperature-sensitive device disposed in the transistor module, the second output terminal coupled to a fourth pin via the isolator, and the reference terminal coupled to the first output terminal.

    Abstract: An isolated insulated gate bipolar transistor (IGBT) gate driver is provided which integrates circuits, in-module, to support the measurements of threshold voltage, and collector-emitter saturation voltage of IGBTs. The measured gate threshold and collector-emitter saturation voltage can be used as precursors for state of health predictions for IGBTs. During the measurements, IGBTs are biased under specific conditions chosen to quickly elicit collector-emitter saturation and gate threshold information. Integrated analog-to-digital converter (ADC) circuits are used to convert measured analog signals to a digital format. The digitalized signals are transferred to a micro controller unit (MCU) for further processing through serial peripheral interface (SPI) circuits.

    Abstract: In a gate driver, a comparator input is adapted to be coupled through a resistor and a diode to a first transistor. A latch input is coupled to a comparator output. A second transistor has a first control terminal and a first output terminal. The first output terminal is adapted to be coupled to a control terminal of the first transistor. A third transistor is smaller than the second transistor. The third transistor has a second control terminal and a second output terminal. The second output terminal is adapted to be coupled to the control terminal of the first transistor. Control logic has a logic input and first and second logic outputs. The logic input is coupled to a latch output. The first logic output is coupled to the first control terminal. The second logic output is coupled to the second control terminal.
