  • Publication number: 20230170790
    Abstract: A method of discharging a link capacitor coupled between link nodes of a multiple phase inverter in which each phase comprises a pair of switches coupled in series between the link nodes, including turning off a first switch of a first phase, turning on a second switch of the first phase, and while the second switch of the first phase remains turned on, activating the first switch of the first phase with pulses and monitoring a link voltage across the link nodes until the link capacitor is discharged. Pulse width and duty cycle may be adjusted, or may remain fixed while pulse magnitude is adjusted until a desired discharge rate is reached. The temperature of pulsed phase switches may be monitored in which discharge operation is suspended while temperature is above a threshold. The switches of multiple phases may be pulsed to distribute discharge among multiple phases.

  • Patent number: 10742443
    Abstract: A method for transmitting messages in a data bus system, wherein the messages can be transmitted in the form of data frames by a data bus and a data frame that is to be sent by a bus subscriber is checked for a piece of changeover information, which method is furthermore distinguished in that changeover of the rise time and/or edge shape of edges of bit pulses of the data frame that is to be sent is performed on the basis of the presence of a defined value of the piece of changeover information. In addition, a corresponding transceiver and to an electronic control unit is disclosed.

  • Patent number: 9442508
    Abstract: A reference voltage source comprises a bandgap voltage reference circuit having a first node and an output node, the output node being arranged for providing a reference voltage. A curvature correction circuit has an input node connected to the output node and/or to a base of a first bipolar device of the bandgap voltage reference circuit and/or to a base of a second bipolar device of the bandgap voltage reference circuit. The curvature correction circuit has an output node connected to the first node of the bandgap voltage reference circuit. The curvature correction circuit comprises a current source for providing a current having a different temperature dependency than a temperature dependency of a first current through the first bipolar device of the bandgap voltage reference circuit.
