Systems and methods for integrated gate driver for inverter for electric vehicle
A system includes: an inverter configured to convert DC power from a battery to AC power to drive a motor, wherein the inverter includes: a first power module including: a first connection; a second connection; a first power switch including a first gate terminal, the first power switch configured to control a first flow of current between the first connection and the second connection based on a first signal to the first gate terminal; and a first point-of-use controller configured to provide the first signal to the first gate terminal to control the first power switch.
Systems and methods for decoupling capacitor for inverter for electric vehicle
A system includes: an inverter configured to convert DC power from a battery to AC power to drive a motor, wherein the inverter includes: a first decoupling capacitor configured to be connected to a positive connection of the battery and a negative connection of the battery; and a first power module including: a first upper phase switch configured to control a first upper phase flow of current between the positive connection of the battery and a first phase connection of the motor, and a first lower phase switch configured to control a first lower phase flow of current between a negative connection of the battery and the first phase connection of the motor.
WET-TACK SINTERING METHOD AND APPARATUS
Prior to sintering a component to a carrier, a portion of a sintering surface at or adjacent to a first side of the component is caused to contact a sintering paste applied on the carrier when a second side of the component that is opposite to the first side is supported by a support mechanism, such that the sintering surface of the component is tilted relative to the carrier. The support member is then moved to gradually reduce a distance between the second side of the component and the carrier so as to cause a remainder of the sintering surface of the component to contact the sintering paste. Therefore, air that is present between the component and the sintering paste may be removed before the component is sintered to the carrier.
Systems and methods for active and passive cooling of electrical components
A power module includes: a fin housing including a fluid passage; a power switch having an exterior surface; and a fin system comprising a plurality of fins attached to a base plate, the plurality of fins extending from the base plate and away from the exterior surface of the power switch, the fin system being in thermal connection with the exterior surface of the power switch and disposed within the fluid passage.
Systems and methods for controlled active discharge for inverter for electric vehicle
A system includes: an inverter configured to convert DC power from a battery to AC power to drive a motor, wherein the inverter includes: a power switch including a drain terminal, a source terminal, and a gate terminal; and one or more controllers configured to: detect a temperature of the power switch, a rate of change in current of the power switch, and a filtered current of the power switch, and control a pulse width of a gate control signal to the gate terminal based on the detected temperature of the power switch, the detected rate of change in current of the power switch, and the detected filtered current of the power switch.
