Simulation of control and measurement systems for dc-ac inverter

Abstract

Computer simulation can reduce the cost of creating new technical devicesand modernization of existing ones.This article includes the model control system and measurement system for DC-AC inverter. Control systems for two-, three- and four-level inverters are considered.The models are made by means of computer simulation in the program OrCAD Capture. Each model is built with the help of universal blocks, which are found in other computer simulation programs.The results of research on the considered models are given.These results show the dependence of the inverter output voltage parameters on the change of the control signals mode.
