Patent number: 8405992Abstract: A power-electronic arrangement comprising semiconductor components (102, 103, 107), a heat exchanger (110), and an electrically conductive element (109) is presented. The heat exchanger comprises evaporator channels (111) and condenser channels (112) for working fluid. The electrically conductive element comprises a contact surface providing a thermal contact to outer surfaces of walls of the evaporator channels for transferring heat from the electrically conductive element to the evaporator channels. A main current terminal of each semiconductor component is bonded to the electrically conductive element which thus forms a part of a main current circuitry of a power system. As the main current terminal is directly bonded to the electrically conductive element cooled with the heat exchanger, the temperature gradients inside the semiconductor components can be kept moderate, and thus the temperatures inside the semiconductor components can be limited.Type: GrantFiled: October 1, 2010Date of Patent: March 26, 2013Assignee: ABB Research Ltd.Inventors: Berk Yesin, Bruno Agostini, Christoph Haederli, Chunlei Liu, Francesco Agostini, Hamit Duran, Slavo Kicin
