An optocoupler may receive the output signal, and a zener diode may be in electrical parallel with an output side of the optocoupler. The switch may be an insulated gate bipolar transistor or a thyristor in different embodiments.

摘要： A high-voltage discharge circuit diagnostic system includes a high voltage DC link with a positive DC link and a negative DC link, a first resistor selectably connectable between the positive DC link and the negative DC link, and a second resistor connected between the positive DC link and the negative DC link. A control module connects the first resistor between the positive DC link and the negative DC link until the high voltage DC link discharges to a first voltage after which the control module disconnects the first resistor from between the positive DC link and the negative DC link to permit continued discharge of the high voltage DC link through the second resistor to a second voltage through an elapsed time period. The control module diagnoses a fault in the second resistor based upon the first voltage, the second voltage, and the elapsed time period.

摘要： A vehicle includes an energy storage system (ESS) rechargeable using electrical power from an off-board AC power supply, a traction power inverter module (TPIM), one or two motors, and a controller. The TPIM has two inverters. The controller energizes designated semiconductor switches of the TPIM and designated induction coils of the motor to boost electrical power from the AC power supply for charging the ESS when the vehicle is not running. With two motors, a contactor allows induction coils of a first motor to be connected to the switches of the first inverter as an input filter, and an additional semiconductor switch is positioned between the ESS and an output side of the switches of the second inverter. A controller charges the ESS by energizing designated semiconductor switches of the TPIM and induction coils of the motor to charge the ESS without using an onboard battery charger module.

摘要： The combination of an intake air supply system with an internal combustion engine having a charge air cooler, a cylinder charging air intake and an exhaust discharge is provided. The intake air supply system includes a Roots-type positive displacement blower having inlet and outlet means and an exhaust gas driven turbo-compressor connected in series with the blower. The intake air supply system further includes a bypass passage connecting the blower inlet and outlet and a valve in the bypass passage to control the flow of fluid through the bypass. The valve is operative to open and close the bypass passage in response to engine operating parameters and to modulate the flow area of the passage in response to the same engine operating parameters so as to infinitely vary the flow area between the open and closed positions of the valve. The valve is modulated to operatively maintain the bypass passage at least partially open at engine idle, whereby the valve means permits bypass flow to recirculate air flow from the blower outlet to the inlet to reduce or limit the engine power absorbed by the blower or to conduct additional air flow around the blower directly from the turbo-compressor to the engine intake to avoid the restriction of the blower to increased charging air flow. A single valve means thus provides a dual function capability.
