Abstract: A power connector is provided that is configured to conduct a current. The power connector includes a base structure, an extension structure, and a connector head structure that define a current path for the current. The extension structure is coupled to and extends between the base structure and the connector head structure. The connector head structure includes a bore-hole that vertically extends into the connector head structure toward the base structure. The bore-hole is configured to receive a fastener for coupling the power connector to an electrical interface of a device. The connector head structure has a mechanical engagement feature configured to mechanically engage with a torque stabilization tool during a fastening of the fastener to the connector head structure in order to prevent a torque applied by the fastening of the fastener from being transferred to the extension structure.

Abstract: This disclosure describes a control circuit to manage the energy flow for an integrated motor generator (IMG), such as an integrated starter generator (ISG) system. The circuit regulates the output voltage of the IMG when the IMG operates in generator mode. The circuit includes an additional switch for each phase connected in anti-series with the half-bridge circuit for the phase, e.g., the drain of the additional switch connects to the drain of the high-side switch. When the ISG is in generator mode, the additional switches are controlled, e.g., to charge the battery at a constant voltage and current throughout the speed range of the ISG (i.e. high rpm and low rpm). In generator mode, the high-side switches may be turned off, which configures the high-side switches to act as a diode and block battery discharge for low rpm operation when the phase voltages are lower.

Abstract: This disclosure includes systems, methods, and techniques for controlling delivery of power to one or more strings of light-emitting diodes (LEDs). For example, a circuit includes a power converter unit configured to receive an input signal from a power source and generate a first output signal comprising a first voltage, a charge pump configured to receive at least a portion of the first output signal from the power converter unit and generate a second output signal comprising a second voltage, and a linear regulator configured to receive the second output signal from the charge pump and generate a third output signal comprising a third voltage.

Abstract: Relays can be used in a variety of applications that use a smaller signal to control a higher power load. Some example loads include motors, stadium lighting and the like. Mechanical relays consist of a coil controlling a magnet that moves electrical contacts. Solid state relays can offer advantages such as lower power consumption and higher reliability than mechanical relays. However, using a solid state relay in a system designed for a mechanical relay can require some significant changes to the system. This disclosure presents a device, a system and technique to operate a solid state relay (SSR) in applications that use mechanical relays while minimizing the need for potentially costly modifications.
