Abstract:
A modular intermediate circuit for a power converter has at least two or more intermediate circuit capacitor modules connected in parallel and in a chain, each intermediate circuit capacitor module having a first terminal, a second terminal, and at least one first intermediate circuit capacitor, which is electrically connected with the first terminal and the second terminal. First terminals of the intermediate circuit capacitor modules each following immediately one after another in the chain are connected in each case through a first low-resistance, high-inductance connection and a first high-resistance, low-inductance connection that is connected in parallel thereto. Second terminals of the intermediate circuit capacitor modules each following immediately one after another in the chain are connected in each case through a second low-resistance, high-inductance connection and a second high-resistance, low-inductance connection that is connected in parallel thereto. A converter circuit, an energy converter, and a vehicle are also disclosed.
