Switching-Cycle Control For The Modular Multi-Level Converter
This new control approach provides an operation mode on which the module capacitor ripple of the modular multilevel converter (MMC) can be reduced to roughly 10% of conventional design. This means that the capacitance value of the converter can be reduced to 10% of original design if meeting the same design criteria. The capacitor rated current is ...

An Algorithm and Implementation System Architecture for the Measurement of Impedances in the D-Q Frame Domain
The growing need for a highly reliable electrical supply for critical applications has spawned the development of local distribution systems with the extended use of power electronics. The advantages are numerous. The downside is that the higher interactions within the system can easily lead the system to operate outside its limits due to instabili...
