Abstract

In the last decades, the applications of power inverter increased rapidly. As a result, in spite of rectifier, an inverter with a high-power electronic oscillator has capability to convert direct current (DC) into alternating current (AC) in different forms. In this paper, a new fuzzy logic control (FLC) is suggested to an improved modeling inverter of a single-phase voltage source using LC filter and voltage sensor. Moreover, two sliding and fuzzy modes of non-linear voltage inverter controller are simulated and compared. The results proved the high efficiency and performance of the proposed method while reduce total harmonic distortion (THD) under linear loading conditions as well. All the data are applied on emergency power supply (EPS).
