Inverter circuit with short cicuit protection

摘要

The circuit has a d.c. circuit (1) formed by a d.c. voltage division system (2.1) with first and second energy storage devices (3,4) and a fuse (5) in series and at least one pair of branches (6) with power semiconducting switches per phase (R,S,T) in parallel with the d.c. circuit. The fuse forms the connection between the first and second energy storage devices.
