This paper compares and evaluates the performance of Sinusoidal Pulse Width Modulation (SPWM) and Space Vector Pulse Width Modulation (SVPWM) techniques for a three-level inverter by cascading two two-level inverters. In this topology, four power semiconductor switches are used per phase and a total of twelve switches are required. The simulation study shows that SVPWM is superior to SPWM in th...

The paper presents three different computational schemes for achieving space vector pulse width modulation, in the control of a multilevel flying capacitor inverter. Each scheme uses the same method of achieving cell-capacitor voltage balancing. Results of realistic simulations are used to compare and contrast these approaches. The timing control of the inverter switches and output performance ...

This paper presents a Modified control method for Space Vector Modulated (SVM) Z Source inverters. Proposed algorithm provides a modified voltage vector with single stage controller having one degree of freedom wherein traditional controllers have two degrees of freedom. Through this method of control, the full utilization of the dc link input voltage and keeping the lowest voltage stress acros...

In this paper, a seven level modified cascaded multilevel inverter is proposed for industrial drive applications. Apart from selecting the conventional level inverters, Multi level inverters has been chosen for the industrial drive applications as it reduces the total harmonic distortion. The involvement of higher number of switches increases the complexity of the system, which leads to losses ...

Abstract: This paper presents Simulation of three phase PWM Inverter fed Induction Motor Drive using Pspice. The proposed induction motor drive model employs only seven switches and incorporates an active current shaping feature. The boost converter at the input can give the required voltage at the input of inverter. The boost converter also improves the power factor. The drive works satisfacto...

Multilevel inverters produce a staircase output voltage from DC voltage sources. Requiring great number of semiconductor switches is main disadvantage of multilevel inverters. The multilevel inverters can be divided in two groups: symmetric and asymmetric converters. The asymmetric multilevel inverters provide a large number of output steps without increasing the number of DC voltage sources an...

Abstract The main electricity supply is PLN, which not always continuous in its distribution, one day there will be blackouts caused by disturbances the transmission or distribution system and limited availability of fossil energy. This can result disruption human activities productivity. solution to this problem develop an Automatic Transfer Switch on a hybrid that utilizes Android-based solar...
