Fuzzy Model Reference Adaptive Control of power converter for unity power factor and harmonics minimization

Abstract

The absorbed current by the converter is rich in harmonics. This provokes the disruption of the network and influences on the consumers joined to the same node. On the other hand, because of its structure and of the absence of the degree of liberty in the control, the converter consummates a reactive power. In order to minimize the harmonics of side network, several techniques of passive filtering and/or active are used. He is more economical of using some filters set in resonance to the frequency of the harmonic to eliminate. In the exercises, the passive filters have some inconveniences this who renders the delicate conception. For it, we interest us only to the active filtering. The aim of this paper is of understating the harmonics of side network and optimizing the exchange a reactive energy between the network and the converter, including the control of power factor and DC-link voltage using Fuzzy Model Reference Adaptive controller (FMRAC).
