TAILIEUCHUNG - Decentralized control multilevel three phase inverter using level shift carrier method

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. | Journal of Science Technology and Food 21 1 2021 23-35 DECENTRALIZED CONTROL MULTILEVEL THREE PHASE INVERTER USING LEVEL SHIFT CARRIER METHOD Nguyen Phu Cong1 Phan Quoc Dung2 1 Ho Chi Minh City University of Food Industry 2 Ho Chi Minh City University of Technology VNU-HCM Email congnp@ Received 6 January 2021 Accepted 5 March 2021 ABSTRACT In recent years the decentralized control structure in multilevel power converters has been increasingly interested in research application implementation in practice because of its outstanding characteristics and techniques compared to traditional methods. One of the key features of decentralized control is the system s ability to extend and dynamically reconfigure the system. 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. The decentralized control method provides basic local connections so that carriers can alternate themselves for the configuration of a multi-cell serial system. Efficient performance of decentralized control in power converters demonstrates power and voltage response suitable for a wide range of applications as well as the ability to dynamically reconfigure the system add or discard a cell . Control method algorithm and structure were evaluated through simulation results on Matlab Simulink.
