We propose a reduction scheme for system constituted by two coupled harmonically-bound Brownian oscillators. reduce the description constructing lower dimensional model which inherits some of basic features original dynamics and is written in terms suitable transport coefficients. The proposed procedure twofold: while deterministic component obtained direct application invariant manifold method...

Solar energy sources are widely available, but in the form of DC source. It is connected in distribution system by means of converting DC/AC supply. It is achieved by means of inverter. To get efficient AC source we use multilevel inverter (MLI). The popularly used inverter is cascaded H-bridge MLI. As the step increases, the AC output nearly becomes same as sinusoidal. The purpose of the proje...

The reduction of high harmonic content in the grid side current is achieved by different harmonic compensating techniques. In order to accomplish it, selective harmonic compensation is carried out in grid-connected photovoltaic inverters by means of resonant harmonic compensators. The harmonic compensator shown in this paper is lead lag compensator. This paper shows a systematic design procedur...

This paper analyses two schemes of single-stage diode-switched active filters used in new switching power supplies designs to improve the power factor. From the point of view of the power flow, the distortion reduction is based on the improvement of the power conversion processes. Most of the ca/cc switching power supplies consists of two separated parts: a rectifier – in most cases a diode bri...
