Problems solved by technology

[0003] State-of-the-art capacitors are often difficult to integrate into the rest of the circuit arrangement or inside the housing
Furthermore, state-of-the-art capacitors often have to be protected against mechanical vibrations and shock loads by cost-intensive measures
A further disadvantage is that especially larger capacitors cannot usually be arranged very close to switching elements such as semiconductor switches of rectifiers or inverters

Embodiment Construction

[0040] according to figure 1 and 2 , the circuit arrangement has a first capacitor 1 . The first capacitor 1 is an integral part of the first capacitor arrangement 2 which surrounds the cavity 3 in an annular manner. The first capacitor 1 is preferably designed as a wound capacitor. In general, wound capacitors are known especially in the form of film capacitors and electrolytic capacitors. The first capacitor arrangement 2 may for example have an inner diameter D of between 8 cm and 50 cm. The first capacitor arrangement 2 also has a height H, for example likewise between 8 cm and 50 cm. The wall thickness d is usually at least 5 mm and can be up to 3 cm. In individual cases, however, these values ​​may vary.

[0041] At least one further circuit part 4 is arranged—at least partially—in the cavity 3 . The further circuit part 4 is preferably—but not necessarily—designed to be radially symmetrical or to have at least a certain periodicity when viewed in the circumferent...

Abstract

An electrical circuit arrangement has at least one capacitor (1) and at least one other circuit part (4) electrically cooperating with the first capacitor (1). The first capacitor (1) is part of a first capacitor arrangement (2) which annularly surrounds the cavity (3). The other circuit part (4) is provided at least partially within the cavity (3) and is electrically connected to the first capacitor (1). The first capacitor arrangement (2) has fastening elements (7) by means of which the circuit arrangement can be mechanically fastened to a holding element (8).

Description

technical field [0001] The invention relates to a circuit arrangement according to the preamble of claim 1 . Background technique [0002] Circuit arrangements are known in various configurations. In such circuit arrangements, capacitors usually occupy a considerable part of the installation space. This applies in particular to intermediate circuit converters, which often require large capacitances between the rectifier and the inverter. [0003] Capacitors of the prior art are often difficult to integrate into the rest of the circuit arrangement or inside the housing. Furthermore, state-of-the-art capacitors generally have to be protected against mechanical vibrations and shock loads by cost-intensive measures. A further disadvantage is that, in particular, larger capacitors generally cannot be arranged very close to switching elements such as semiconductor switches of a rectifier or an inverter. However, a close arrangement is technically advantageous. [0004] In the...
