摘要： An electronics assembly which includes a grounding connection, having a housing, a connector, a portion of the connector formed around the housing, a recess portion integrally formed as part of the connector, a substrate located in proximity to the connector, and circuitry mounted to the substrate such that the circuitry is at least partially disposed in a cavity formed as part of the connector. A conductor is mounted to the connector such that the conductor is located in the recess, and the conductor is in contact with the housing and the substrate. A grounding connection is formed between the circuitry and the housing when the conductor is in contact with the housing and the substrate. The conductor may be made of an elastomeric material, and the conductor deforms when the substrate is placed in proximity to the connector.

摘要： A control unit having a connection structure for connecting components of the control unit to a base plate which eliminates the need for separate fasteners. The control unit includes circuitry mounted to a PCB, and the PCB is pre-assembled to a base plate, to form a pre-assembly. During assembly, the PCB and the base plate are aligned when placed in a tooling device which clamps and holds the pre-assembly in place during the over molding process. The circuitry is over molded with an epoxy material, such that the epoxy material flows from a top side of the PCB to underneath the base plate, and the PCB is fixed to the base plate without the use of fasteners such as screws, or adhesive materials.

摘要： A heat dissipation structure for a belt starter generator (BSG) which reduces the temperature of one or more ground screws used to connect a printed circuit board (PCB) to a cooling device of the BSG. The PCB is part of an inverter, and the inverter of the BSG is grounded using two ground screws that fix the PCB to the cooling device. A heat dissipation bridge is connected to the two ground screws, the PCB, and the cooling device. The heat dissipation bridge is connected to the grounds screws such that the heat dissipation bridge is located and in contact with an area of the cooling device where the coolant is flowing through a flow cavity. The heat dissipation bridge absorbs the colder temperature from the cooling device therefore lowers the temperatures of the ground screws to a safe level for the components of the PCB.

摘要： A power factor correction (PFC) circuit is provided. The PFC circuit includes an input for receiving alternating current and a converter for converting the received alternating current to a direct current. The PFC circuit also includes a direct current link that includes at least one capacitor. Additionally, the PFC circuit includes a voltage regulator control loop operating in burst mode under light load conditions by switching between an ON-state and an OFF-state periodically. The PFC circuit also includes a controller preloading the voltage regulator control loop with an initial value corresponding to the circuit current load under light conditions, when the voltage regulator control loop is transitioning to an ON-state of the burst mode. The initial value is based on the rate of change of the voltage at the direct current link and the capacitance of the capacitor of the direct current link.

摘要： An interleaved switched mode power supply and control method therefor are disclosed. The interleaved switched mode power supply includes a first switched mode power supply; a second switched mode power supply; and a controller. The controller controls the first and second switched mode power supplies so that the controller and the first and second switched mode power supplies form an interleaved switched mode power supply with power factor correction. The controller modulates a switching frequency of each of the first and second switched mode power supplies such that the switching frequency varies based upon ripple current cancellation between the ripple current of the first switched mode power supply and the ripple current of the second switched mode power supply.

摘要： A wireless power transmission method of control is disclosed where equalization of the reactive voltages of a series resonant circuit, which is part of a transmitter antenna tuning and coupling unit, is obtained by adjusting the switching frequency and thereby used to determine a switching frequency of the driving high frequency inverter. By measuring and largely equalizing the voltage parameters of the series resonant circuit to establish an inverter switching frequency, improved efficiency of the wireless power transmission method.
