Abstract: A system includes: an inverter configured to convert DC power from a battery to AC power to drive a motor, wherein the inverter includes: one or more switches; and one or more controllers configured to: determine a gate voltage to operate the one or more switches of the inverter based on a temperature of the inverter; operate the one or more switches based on a pulse width modulated (PWM) signal and the gate voltage to initiate an active discharge of a bus voltage of the inverter; and while the bus voltage is greater than a first threshold voltage, accelerate the active discharge of the bus voltage by operating the one or more switches and by performing one or more of increasing the gate voltage or decreasing a wait time following a pulse of the PWM signal.

Abstract: A system may include a printed circuit board (PCB), wherein the PCB includes an opening. A system may include a transformer including: a housing including a first end extending in a first plane and a second end extending in a second plane, the second end configured to be inserted into the opening in the PCB; and one or more leads extending from the housing, wherein an end of the one or more leads is configured to be connected to the PCB and to be disposed between the first plane and the second plane.

Abstract: 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 bulk capacitor; one or more switches; a gate driver; and one or more controllers, wherein the one or more controllers are configured to provide one or more of a gate voltage or a pulse width modulated (PWM) signal to the gate driver to control the one or more switches to discharge the bulk capacitor.

Abstract: A system for staging a mobile device is described. The mobile device includes a processor that executes a software application. A memory stores a unique identifier for the mobile device. The unique hardware identifier is readable by the software application and unreadable by any system that is external to the mobile device. The mobile device also includes a radio frequency identification (RFID) tag associated with the mobile device. The RFID tag stores a unique serial number that is readable by a staging system external to the mobile device and by the software application. The staging system encrypts a staging profile using both the unique serial number and the unique hardware identifier to create a device-specific key. The staging system writes the encrypted staging profile to the RFID tag.
