Three-phase distribution choke for double converter and with integrated dV/dt filter
Three-phase distribution choke for double converter and with integrated dV/dt filter
Description
The distribution choke couples two converters in a back-to-back topology, which allows bidirectional power control in the converters. In addition, it coasts at the output of a filter inductance dV/dt common to both converters.
