Embodiment Construction

[0013] The present invention can be applied in conjunction with a variety of inverter solutions, and thus is not limited to use with any particular type of equipment. For example, an inverter unit, a combination of an inverter unit and an inverter supply unit, and a three-level inverter unit are proposed here as embodiments of the invention. However, those skilled in the art should understand that the present invention should not be considered limited to the three devices or their combinations. The type of supply supplied by the inverter, the loads controlled by the inverter or the connections between them, eg voltage levels or phase numbers, are also irrelevant to the basic idea of ​​the invention. Furthermore, the external or internal electrical connections of the inverter incorporated in the application of the invention are not relevant for the invention and are therefore omitted from the figure for the sake of clarity. The invention is not limited to the examples shown in...

Abstract

The invention relates to an arrangement for a modular inverter. The arrangement comprises a number of power semiconductors (5, 7) and cooling elements (2), the cooling elements being connected to the power semiconductors (5, 7) for cooling them, wherein the power semiconductors (5, 7) and the cooling elements (2) are disposed around a centre axis (9) of the arrangement in such a manner that they demark a channel (10) around the centre axis (9) in which a cooling medium is able to flow in the direction of the centre axis. The invention is characterized in that the arrangement further comprises a first tube-shaped ring film capacitor (11) around the centre axis (9) of the arrangement wherein the power semiconductors (5, 7) are arranged between the cooling elements (2) and an inner surface of the first ring film capacitor (11).

Description

technical field [0001] The invention relates to a modular inverter device. Background technique [0002] An inverter is an electrical device capable of generating a voltage with a variable frequency. Typically, an inverter is used in conjunction with a motor for controlling it at a variable frequency or accordingly when transmitting electrical power back to the network, whereby the inverter must generate a voltage with a frequency corresponding to the network frequency. Such inverters supplying power to the network are often referred to as network inverters. An inverter can also be part of a frequency converter used to control a motor or other load. Frequency converters are generally formed from two converters, namely a rectifier and an inverter, between which a direct voltage or direct current intermediate circuit is present. The rectifiers and inverters may also be located physically apart from each other and one rectifier may power multiple inverters via a common inter...
