Embodiment Construction

[0081] exist figure 1 An embodiment is shown in , which comprises a first heating element 1 on which a first capacitor region 2 is arranged. The first capacitor region 2 comprises dielectric layers 3 between which internal electrodes 4 are arranged. The heat generated in the first heating element 1 can be transferred directly to the first capacitor region 2 by the direct contact of the first heating element 1 with the first capacitor region 2, so that, for example, the dielectric constant of the dielectric layer 3 can be increased , which results in an increase in the power of the capacitor. In this case, a material with a dielectric constant that increases with increasing temperature is used for the dielectric layer 3 . This applies at least to the temperature range to which the first heating element 1 can be heated. Materials for the dielectric layer can include ferroelectric or antiferroelectric materials. This also applies to the dielectric layer of the following figur...

Abstract

The invention relates to a capacitor comprising the following components: a first heating element (1), a first capacitor region, comprising: dielectric layers (3), internal electrodes (4) which are arranged between the dielectric layers, wherein the first heating element and the first capacitor region (2) are connected to each other in a thermally conductive manner.

Description

technical field [0001] The invention proposes a capacitor according to claim 1 . Background technique [0002] A common problem with capacitors is increasing their power. [0003] The problem has hitherto been solved in that the dielectric materials with different dopings are arranged in a layer sequence that overlaps one another, for example as core and outer shell. In conventional capacitors, dielectric materials are usually used which have a dielectric constant which is as temperature-independent as possible over a large range. As a result, changes in the permittivity of the dielectric material of the capacitor and changes in the electrical properties of the capacitor when the ambient temperature changes are to be avoided. Contents of the invention [0004] This object is achieved by a capacitor according to claim 1 . Further embodiments of the capacitor and the capacitor module are the subject-matter of further subclaims. [0005] Embodiments of the present inventi...
