Abstract

A circuit arrangement includes a power semiconductor circuit, a first charge storage unit and a second charge storage unit. The first charge storage unit has first and second terminals, the second charge storage unit has first and second terminals, and the power semiconductor circuit has first and second terminals. The power semiconductor circuit also has a first semiconductor component and a second semiconductor component, the load paths of which are electrically connected in series between the first and second terminals of the power semiconductor circuit. A first connection electrically connects the first terminal of the first charge storage unit to the first terminal of the second charge storage unit, and a second connection electrically connects the second terminal of the first charge storage unit to the second terminal of the second charge storage unit. A magnetic core is electromagnetically coupled to the first and/or second connections.
