Abstract:
Method for controlling the parallel operation of multiple d.c. voltage converters, in which one of the d.c. voltage converters performs a master function and at least one other d.c. voltage converter performs a slave function, whereby the d.c. voltage converter performing a master function works with voltage regulation, and the at least one other d.c. voltage converter works as current source, characterized in that the d.c. voltage converter with voltage regulation covers the total current demand when a total current demand is less than the half nominal current of the d.c. voltage converter with voltage regulation, and it delivers its half nominal current when a total current demand lies between the half nominal current and the nominal current of the d.c. voltage converter with voltage regulation, and the remaining current demand is covered by the d.c. voltage converters working as current source.
