This work proposes three phase five level Bridge module type Diode Clamped Multilevel Inverter (DCMLI) using various modulating techniques for induction motor load. These Pulse Width Modulating (PWM) techniques include Carrier Overlapping (CO) strategy, Variable Frequency (VF) strategy, Phase Shift (PS) strategy and Sub-Harmonic Pulse Width Modulation (SHPWM) i.e. Phase Disposition (PD) strateg...

This paper presents a comprehensive analysis of various bipolar Multicarrier Pulse Width Modulation (MCPWM) strategies with Sinusoidal reference for three phase Nine level Trinary Source cascaded inverter. A new approach of nine levels is for medium voltage applications. The proposed topology uses reduced number of switching devices and thus reducing losses and low THD in comparison with the co...

The aim of this paper is to investigate the power factor correction (PFC) of Boost Converter under an average current-mode control. Boost converter topology is used to accomplish this active power-factor correction in many discontinues/ continuous modes. The boost converter is used usually it is easy to implement and works well. In this paper comparative evaluation of different techniques for h...

Since 1965, thalidomide (Thd) has shown dramatic efficacy in alleviating the signs and symptoms of erythema nodosum leprosum (ENL). Despite its well-known teratogenic effects, it is the treatment of choice for acute ENL, with recommended oral doses up to 400 mg daily. The mechanism(s) by which Thd causes deformities in embryos and attenuates ENL, a major cause of morbidity in lepromatous lepros...

To achieve maximum possible power factor and by keeping total harmonic distortion (THD) within the acceptable limit. A new control algorithm of shunt active power filter under distorted grid voltage and unbalanced supply conditions is proposed. A new control algorithm renders the optimal compromise between harmonic free (HF) and unity power factor (UPF) by keeping the total harmonic distortion ...

In this paper, it is first attempted to provide a small signal model of the photovoltaic (PV) system, DC-DC boost converter, and pulse width modulation (PWM) generator. Then, technique provided for maximum power point tracking (MPPT) in grid-connected solar systems based on variable adaptive perturbation observation with predictive control PV current. An innovative aspect proposed current metho...
