In emerging present day technologies, CSC modes are becoming much more important (for permanent magnet motor applications). With permanent magnet motor applications, if the permanent magnet motor is connected as a load to Xn/Yn, the motor generates electric current after shutdown which introduces unwanted feedback into the A-PS 300. But with a permanent magnet motor connected as a load to Xn/Yn with CSC operations (mode CM6), the inductor L2 functions as a current-limiting safety device.
Exemplary Power Converter
In a simplest-case scenario, a relatively modest electrical system 100 may have only a single power converter 500.A, and the single power converter 500.A in turn may itself be a single A-PEBB LRU 200.A. For example, a “l(fā)ower end” large-scale electrical system 100 (which may perhaps be referred to as a “medium scale electrical system”) may employ one power converter 500 with a single A-PEBB LRU 200 which may be rated at 1000 volts and 125 kW.
