Abstract
A power supply assembly including a plurality of power supply modules which can be operated in parallel and are inserted or can be inserted into a common switch cupboard or rack or into a plurality of switch cupboards or racks, each power supply module having an inverter branch for continuously supplying electric power to a load at the output in a load branch. The power supply assembly also has a bypass assembly that ensures the power supply when power supply through the inverter branch fails or is insufficient. The reliability of the power supply is enhanced if each of the power supply modules has a bypass which is connected to the load branch, in parallel to the inverter branch. The bypass is separated from the load branch when the inverter path works properly and in the event of failure of an inverter branch, can be automatically connected by a control circuit to the load branch in order to maintain power supply.
