Design of A 3.75kVA Inverter With Multi-Level Pulse Width Modulation

Fonkwe Edwin obtained his "Diplôme d'Ingénieur de Conception" from the Ecole Nationale Supérieure Polytechnique Yaoundé in 2009. He is currently studying an MSc in Electrical Power Engineering at the Masdar Institute of Science and Technology, Abu Dhabi.

The Cameroonian grid suffers from transient and permanent overvoltages, voltage dips, harmonics and phase disequilibrium. These problems are faced by many other grids in the world. This led to the invention of the UPS (Uninterruptible Power Supply). As its name indicates, the UPS carries out Power Processing on the power signals such that a clean and stable power of high quality is delivered at its output. Unfortunately, most commercial UPS and inverters, especially for off-grid applications, do not have high power ratings. Solar PV off-grid stations have a problem of finding high-power off-grid inverters. This work is aimed at providing a step towards solving this problem. This book is recommended for those interested in the domain of switch mode power supplies. In particular, the reader shall find in-depth analysis of the buck, boost, and h-bridge converters with integrated microcontroller.
