Multifunctional power converter circuit for switching switching-network into different switching states during e.g. charging high-volt battery in electric car, has inductor connected to terminal for providing voltage to another terminal

摘要

The circuit (40) has a bridge circuit (42) comprising three inductors (44a-44c) that are connected to central nodes (45a-45c) of respective half-bridges (42a-42c). One of the inductors is connected to a direct voltage terminal (18) over a switching-network (46) in a switching state (52) of the switching-network in order to provide direct current (DC) voltage (V18ab) to the voltage terminal based on voltage that is applied to another direct voltage terminal (32) or to provide another DC voltage (V32ab) to the latter voltage terminal based on the voltage applied to the former voltage terminal. An independent claim is also included for a method for operating a power converter circuit.
