Reforms in the electricity sector along with various renewable-energypromotion policies have increased the importance of small grid-connected photovoltaic (PV) systems utilizing single-stage single-phase inverters. Ruggedness, reliability, and cost effectiveness are the desirable characteristics of such inverters used in distributed low-power applications.(More)
Grid-connected unity-power-factor converters based on one-cycle control (OCC) do not require the service of phaselocked loop or any other synchronization circuits for interfacing with the utility. As a result, these schemes are becoming increasingly popular. However, as the power handled by the converter increases, the power factor deteriorates. To(More)
The widespread usage of load compensators for carrying out harmonic and reactive power compensation is constrained by cost and poor efficiency due to switching losses. Hence, it is customary to employ active harmonic filters for harmonic compensation only, while traditional methods comprising of thyristor-switched capacitors are used to carry out reactive(More)
Plants display an extraordinary ability to regenerate complete shoot systems from a tissue fragment or even from a single cell. Upregulation of the determinants of pluripotency during a precise window of time in response to external inductive cues is a key decisive factor for shoot regeneration. A burst of recent studies has begun to provide an(More)
The electricity sector in the country have many critical issues regarding the electricity supply, so the renewable energy policies have increased the consumption of solar energy. This paper proposes the single stage inverter with MPPT ( maximum power point tracking) and one cycle controlled (OCC) for the grid connected PV system. OCC scheme is predicated on(More)
