This study presents the application of a decentralized control structure of multilevel inverters using the level shift carrier pulse width modulation method (LSC-PWM) as the control algorithm. For the traditional control method, the carrier signal is provided by a central controller.

(BQ) In addition to updates in nearly every chapter, this highly regarded reference brings to the Handbook its original contributions, discussing phase-shifting, rectifier, and constant-voltage transformers as well as power transformer protection and transient-voltage response. It also includes two new sections in the chapter on reactors, covering installation considerations for dry-type air-core reactors as well as line traps and power line carrier communication-, data-, and protective-relaying systems.

Digital Modulation Techniques There are three ways in which the bandwidth of the channel carrier may be altered simply. It is worth emphasizing that these methods are chosen because they are practically simple, not because they are theoretically desirable. These are the altering of the amplitude, frequency and phase of the carrier sine wave. These techniques give rise to amplitude-shiftkeying (ASK), frequency-shift-keying (FSK) and phase-shift-keying (PSK), respectively. ASK describes the technique the carrier wave is multiplied by the digital signal f(t)....
