Patent number: 11309803Abstract: A converter circuitry between a first network, which may be either a poly-phase medium-voltage alternating current (AC) network, at least one polyphase low-voltage AC network or at least one direct-current (DC) network, and a second network, which may be either a polyphase medium-voltage AC network or a medium-voltage DC network, wherein the converter circuitry comprises at least one power bus and low-voltage power cells both at the first and at the second network side such that each power cell is connected to a power bus via a transformer. Each power bus is connected to a low-voltage power unit, which is able to supply pre-charging power via the power bus to all power cell intermediate DC-link filtering capacitors before the converter is started. The low-voltage power unit is also able to take care of a resistor braking in case the first network cannot take the power supplied by the load connected to the second network.Type: GrantFiled: May 20, 2020Date of Patent: April 19, 2022Assignee: Vacon OyInventors: Stefan Schroeder, Dan Isaksson, Risto Komulainen, Stefan Strandberg

Patent number: 9723741Abstract: A housing arrangement of a power electronics device includes one power module or several identical power modules, each module with at least one part connected to a hazardous voltage, the arrangement further including a housing part having room for at least one power module. Each power module includes an enclosure part which essentially surrounds the power module and includes electrically insulating material. All the external connections of the power module are placed on one single wall of the enclosure part. The power modules and the enclosure part of the power modules are arranged such that when the power module is installed to the housing part the power module is electrically insulated from the housing part and external connections of the power module are directed to the front side of the housing part.Type: GrantFiled: May 8, 2015Date of Patent: August 1, 2017Assignee: VACON OYInventors: Devin Dilley, Marc Hoffman, Dan Isaksson
