  • Patent number: 11955882
    Abstract: An active discharge circuit for electric vehicle inverter, the active discharge circuit intended to be connected in parallel with a DC link capacitor connected between positive and negative lines of a DC power link, wherein the circuit comprises a dissipative current source, a switch connected in series with the current source between the DC lines, and a controller connected to the switch and arranged to apply an activation signal in dependence of a control signal, the activation signal placing the switch in a conducting state, wherein the current source is configured to draw a discharge current and dissipate any energy stored in the DC link capacitor when the switch is in the conducting state. As long as the switch is closed by the activation signal, the current source will draw a constant current and dissipate power, and the voltage across the DC link capacitor will decrease linearly.

  • Publication number: 20160106903
    Abstract: The present invention relates to a fluid pump system (64) having a fluid reservoir (21) comprising a first cavity (29) and a second cavity (30) in fluidic communication with each other and adapted to accommodate a biological fluid (7). The fluid reservoir (21) is connected to a fluid-container system (27) and a target (5) is in fluidic communication with the second cavity (30). A pressurization system is adapted to generate a first pressure below ambient pressure in the first cavity (29) and generate a second pressure in the first cavity (29). The second pressure is also applied to the second cavity (30). The fluid pump system (64) thereby causes flow of the biological fluid (7) from the fluid-container system (27) into the first cavity (29), from the first cavity (29) into the second cavity (30), and from the second cavity (30) to the target (5).
