This study presents a synchronized output regulation (SOR) strategy for controlling inverters operating in grid-connected and stand-alone modes. As a concept of networked dynamic systems, SOR involves nodes with outputs that are synchronized but display a desirable wave shape. Under the SOR strategy, inverter and utility are regarded as two nodes that comprise the simplest network. These two no...

Conventional structures of power inverter filters, required for grid coupling operation and to fulfill EMI requirements, lead to a system, which was difficult to control (due to its high system order) and problematic to realize due to unknown mains impedance behavior. In this paper, a matching filter topology is presented, which can overcome all these limitations. It is shown, that the optimal ...

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...

In this paper, topology of a Grid connected solar microinverter is proposed. The DC power obtained from the solar panel is converted into a rectified AC signal. This conversion is realized by an Active Clamped Flyback Converter. A full-bridge inverter which switched at a high frequency converts this rectified AC into sinusoidal AC of power frequency and this also controls the power flow directi...
