Simulation of inverter control method based on Simulation Platform
Abstract: Now, the DC / AC inverter technology includes many basic disciplines, such as power electronics technology, power electronics control technology, DC AC conversion technology, modern circuit theory and design technology. It is an important modern power electronics subject to study the theory and design of inverter circuit. In this paper, taking inverter control system as the research background, the structure and control strategy of the typical inverter in power electronics are studied, and the characteristics of inverter control circuit are also studied. Some control methods such as PID control, state feedback control, non beat control, double loop feedback control, repetitive control, sliding mode variable structure control, fuzzy control and neural network control are introduced in this paper. And then through the analysis of the main circuit of the inverter, understand the principle of the main circuit, and next design the main circuit of the drive circuit and some such as over voltage, over current protection circuit. Finally, some simulation of inverter circuit is simulated by PSIM software.
