Intermediate circuit arrangement and inverter

Abstract

A disclosed intermediate circuit arrangement includes first and second partial circuit boards of identical design having a series circuit of at least two capacitor banks. The partial circuit boards each have a terminal strip having a positive intermediate circuit connection, a negative intermediate circuit connection, and a central connection. The circuit arrangement also includes a connecting circuit board for electrically connecting the respective connections of the terminal strips of the two partial circuit boards to one another. The connecting circuit board is a multi-layer circuit board with two outer metal layers and at least two inner metal layers arranged between the outer metal layers. The outer metal layers have an electric connection between corresponding connections of the terminal strips of the two partial circuit boards, and at least one first metal layer of the inner metal layers has only an electrical connection of the positive intermediate circuit connections of the two partial circuit boards and at least one second metal layer of the inner metal layers has only an electrical connection of the negative intermediate circuits of the two partial circuit boards. The intermediate circuit arrangement can be part of an inverter.
