Parallel connection of a number of half-bridges in h-bridges circuit modules

The invention relates to a parallel connection of a number of half-bridges in H-bridges circuit modules. The invention discloses a circuit arrangement (100) for supplying a unit (200) in a motor vehicle with power, with at least two parallel-connected half bridges (111,112,121,122) that comprise two transistors. The half bridges are integrated in an H-bridge circuit module (110,120). An integrated arithmetic unit (113,123) is adapted to active free-running for integrated half bridges (111,112,121,122) according to activated condition of activation signal.
