Energy efficient contact less suspension of high-speed rotor shafts in application areas such as power-plants and Flywheel Storage Systems (FESS), can be achieved through Active Magnetic Bearings (AMBs). Inevitably, there exists time delay sensing the displacement actual control force by electromagnets, thus leading to system instability. This paper therefore analyses stability AMBs, with const...

A bidirectional converter (BDC) is required in areas where generated energy is stored. Some of the application areas are uninterruptible power system, transportation,, flywheel energy storage systems, etc. Bidirectional flow of power using buck mode and boost mode along with efficiency and high power density is important need of such systems. This report proposes a new topology of BDC with the ...

Modular multilevel converter (MMC)-based high voltage direct current (HVDC) transmission networks integrate remotely located distributed renewable energy resources (RER). The intermittent nature of RER and symmetrical asymmetrical AC-side low-voltage faults produce operational difficulties. It reduces the MMC’s ability to transfer rated power, which raises HVDC link. Therefore, MMC-HVDC network...
