SPACE VECTOR MODULATION FOR TWO LEG INVERTERS
INTRODUCTION
• Semiconductor switches mainly determine the overall price of power converters.
• The main objective of this project is to prove 2leg inverters are the best option for low power applications for getting the good performance.
• Two leg inverter produces the square wave or quasi-square wave. but low power applications allow the two leg inverter output.
• In many industrial applications, it is often required to v..............etc

Title: Efficiency Improvement of Grid-tied Inverters at Low Input Power Using Pulse Skipping Page Link: Efficiency Improvement of Grid-tied Inverters at Low Input Power Using Pulse Skipping - Posted By: project topics

Abstract-
A pulse skipping control strategy is proposed to improve efficiency of grid-tied inverters at light loads. To maximize the efficiency of pulse skipping operation mode, three key parameters are identified and optimized based on a loss model, which is developed to find the maximal efficiency points using a three-dimensional search technique. A 200W prototype inverter was setup to verify the proposed control strategy. The experimental results show that the proposed pulse skipping control strategy greatly impr..............etc

Title: Reduction of common mode currents generated by three-level inverters Page Link: Reduction of common mode currents generated by three-level inverters - Posted By: project topics

Abstract
In adjustable speed drive applications, the switching of the inverter semiconductors generates common
mode currents as well as harmful overvoltages on the motor terminals when long cables are used.
Consequently, bulky and expensive input and output filters must be used. This work aims at reducing
these disturbances from their origin by using a three-level neutral-point-clamped (NPC) inverter
controlled with a new pulse-width-modulation (PWM) strategy. Whereas previous common mode
noise-reducing strate..............etc

Introduction
An inverter is an electrical device that converts direct current (DC) to alternating current (AC); the converted AC can be at any required voltage and frequency with the use of appropriate transformers, switching, and control circuits.
Static inverters have no moving parts and are used in a wide range of applications, from small switching power supplies in computers, to large electric utility high-voltage direct current applications that transport bulk power. Inverters are co..............etc
