Power electronic converters, especially DC/AC Sinusoidal Pulse Width Modulation inverters have been extending their range of use in industry because of their numerous advantages. They typically synthesize the stair –case voltage waveform (from several dc sources) which has reduced harmonic content. This paper aims to extend the knowledge about the performance of Five level Cascaded H-Bridge MLI...

The developments in power electronics technology have led to the developments in the wind energy conversion system (WECS). The output voltage of the WECS depends on the speed of the wind, which is not constant. Hence, a power conversion unit is required to maintain the output voltage of the WECS constant. This paper presents the design of a boost converter and a voltage controller for maintaini...

In this paper a new threephase multi-level inverter topology is proposed. With the increasing requirements for high power at high power quality, such a converter is inevitable. The major advantages of the proposed topology are improved power quality and lesser number of switches. This leads to lesser complexity of the control circuitry, reduction in switching harmonics and reduction in the cost...

A primary goal of these systems is to increase the energy injected to the grid by keeping track of the maximum power point (MPP) of the panel, by reducing the switching frequency, and by providing high reliability. In the last years, multilevel converter topologies have been also considered in PV applications. Multilevel converter topologies can generate high-quality voltage waveforms with powe...
