Induction Machine Drive with Dual Stator Winding
A new dual stator winding induction machine drive is described in this paper. The proposed induction machine consists of a standard squirrel-cage rotor and a stator with two separate windings wound for a dissimilar number of poles. Each stator winding is fed from an independent variable-frequency variablevoltage inverter. The proposed drive offers such advantages as speed sensor less operation,...
متن کاملCapacitor Voltage Monitoring in Modular Multilevel Converter
A Modular Multilevel Converter (MMC) is an attractive solution for power conversion without transformers. As MMC consists of cascade connections and floating dc capacitors, it requires continuous voltage monitoring. An adaptive observer design has been presented to estimate the capacitor voltages from the measurement of arm currents. This work introduces a capacitance value of the cell capacito...

متن کاملSimplified model and submodule capacitor voltage balancing of single-phase AC/AC modular multilevel converter for railway traction purpose
A single-phase AC/AC modular multilevel converter (MMC) can interact directly with 25 kV railway grid without a bulky 50 Hz step-down transformer. This brings in great savings in size and cost. Submodule (SM) voltage balancing of this kind of MMCs remains a major technique issue. This study proposes a voltage-balancing solution for this scenario which consists of intraand inter-arm voltage bala...
متن کاملModified Modular Multilevel Converter
The modular multilevel converter (MMC) is receiving extensive research interests in high/medium voltage applications due to its modularity, scalability, reliability, high voltage capability and excellent harmonic performance. The submodule capacitors are usually quite bulky since they have to withstand fundamental frequency voltage fluctuations. To reduce the capacitance of these capacitors, th...
