STROMRICHTERSYSTEM MIT EINER MEHRZAHL VON STROMRICHTEREINHEITEN

摘要

In a conversion system including a plurality of converter units connected to supply a.c. outputs to a load through a common bus, each converter unit includes a simulation bus circuit adapted to detect simulated lateral current between the converter units. Thus, testing of parallel operation control circuit can be executed easily, based on the simulated lateral current before paralleling the main circuit.
