  The paper deals with the implementation of a Multi-level inverter which is based on cascaded half-bridge, producing a 31 level output with high power quality. This paper primarily focuses on generating high level inverter output with optimal num...

  Multilevel inverters (MLI) are employed mainly to enhance the performance of the drive scheme which generally demands a quality power source. The modulation technique involved plays a vital role in its improvement. The conventional sine pulse width modulation (SPWM) scheme employ...

  In this paper, analysis, design and implementation of non-isolated soft-switching bidirectional DC- DC converter with an active switch are described. The proposed topology gives the output voltage as twice as the input voltage and enhances the efficiency up to 94.5% and 92.9% for...

  A 3-level boost (3LB) converter has the characteristics of higher voltage conversion efficiency, lower inductor current ripples, output voltage ripples and voltage stresses on switches when compared with the conventional boost converters in continuous conduction mode...

  T Multiple output Switched Mode Power Supplies (SMPSs) for personal computers (PCs) and other equipments are normally depict extremely bad power quality indices at the utility interface such as total harmonic distortion of the input current being more than 80%, power factor bei...

  Owing to a small inertia moment, when compared with direct current commutator motors, as well as the vectorial way of control, brushless DC motors (BLDCM) with permanent magnets demonstrate perfect regulating and dynamic properties. The motors have got a number of advantages: sim...
