CPSS Power Electronics Series,2520-8861981-334-384-2 Fundamental of Power Electronics Converter and Pulse-Width-Modulation -- Principle of Pulse-Width-Modulation -- PWM's Impact on System Performance -- Current Ripple Prediction Model -- Variable Switching Frequency PWM -- Phase-shift PWM -- Advanced PWM for Advanced Topologies -- PWM for Common-mode Noise Reduction -- PWM's Implementation in Hardware.This book is a technical publication for students, scholars and engineers in electrical engineering, focusing on the pulse-width-modulation (PWM) technologies in power electronics area. Based on an introduction of basic PWM principles this book analyzes three major challenges for PWM on system performance: power losses, voltage/current ripple and electromagnetic interference (EMI) noise, and the lack of utilization of control freedoms in conventional PWM technologies. Then, the model of PWM's impact on system performance is introduced, with the current ripple prediction method for voltage source converter as example. With the prediction model, two major advanced PWM methods are introduced: variable switching frequency PWM and phase-shift PWM, which can reduce the power losses and EMI for the system based on the prediction model. Furthermore, the advanced PWM can be applied in advanced topologies including multilevel converters and paralleled converters. With more control variablesin the advanced topologies, performance of PWM can be further improved. Also, for the special problem for common-mode noise, this book introduces modified PWM method for reduction. Especially, the paralleled inverters with advanced PWM can achieve good performance for the common-mode noise reduction. Finally, the implementation of PWM technologies in hardware is introduced in the last part.CPSS Power Electronics Series,2520-8861Electric power productionElectronic circuitsElectronicsElectrical Power EngineeringElectronic Circuits and SystemsElectronics and Microelectronics, InstrumentationMechanical Power EngineeringElectric power production.Electronic circuits.Electronics.Electrical Power Engineering.Electronic Circuits and Systems.Electronics and Microelectronics, Instrumentation.Mechanical Power Engineering.621.317Jiang Dong1227589MiAaPQMiAaPQMiAaPQBOOK9910483174903321Advanced pulse-width-modulation2850225UNINA
