This project deals with studying the basic theory of a Sinusoidal Pulse Width Modulated Inverter (SPWM), its Simulink modelling, estimating various designing parameters and various instabilities. The project will be commenced by a basic understanding of the circuitry of the SPWM Inverter, the components used in its design and the reason for choosing such components in this circuitry. After this, it will be attempted to simulate a model circuit on any simulating software e.g. MATLAB and analyse the output waveforms for various values of the elements used in the circuit and hence study the system response and instabilities.

Advancements in grid converter technology have been pivotal in the successful integration of renewable energy. The high penetration of renewable energy systems is calling for new more stringent grid requirements. As a consequence, the grid converters should be able to exhibit advanced functions like: dynamic control of active and reactive current injection during faults, and grid services support.This book explains the topologies, modulation and control of grid converters for both photovoltaic and wind power applications. In addition to power electronics, coverage focuses on the specific applications in photovoltaic and wind power systems where grid condition is an essential factor.With a review of the most recent grid requirements for photovoltaic and wind power systems, the relevant issues are discussed:
Modern grid inverter topologies for photovoltaic and wind turbines
Islanding detection methods for photovoltaic systems
Synchronization techniques based on second order generalized integrators (SOGI)
Advanced synchronization techniques with robust operation under grid unbalance condition
Resonant controller techniques for current control and harmonic compensation
Grid filter design and active damping techniques
Power control under grid fault conditions, considering both positive and negative sequencesThroughout, the authors include practical examples, exercises, and simulation models and an accompanying website sets out further modeling techniques using MATLAB® and Simulink environments and physical security information management (PSIM) software.Grid Converters for Photovoltaic and Wind Power Systems is intended as a course book for graduate students with a background in electrical engineering and for professionals in the evolving renewable energy industry. For professors interested in adopting the course, a set of slides is available for download from the website.Companion Websitewww.wiley.com/go/grid_converters
