A Single-Stage Three-Phase Grid-Connected Inverter with the Center-Tapped Energy Storage Inductor

Since ages, the best alternative for fossil fuel generation is found from Renewable energy sources. One among them is the Solar energy which can produce solar power. Solar power can be taught as “Solar Electricity” and is the most practical, cleanest forms of Renewa-ble Energy. Solar Power Systems otherwise called as PV systems can be of various types like off-grid and on-grid systems. This paper, focuses on Grid connected solar electric system. The paper aims at modelling high performance Three Phase Single Stage Grid Connected Inverter. So as to achieve maximum output from the photovoltaic array, MPPT Tracking is connected. The conversion from DC output of photovoltaic array is done to AC so that it is fed into the grid, a IGBT based inverter is used which converts from DC to AC power. A Simulation model is developed in MATLAB Simulink and results are presented in the paper.

Power Loss Reduction

Purpose This paper aims to propose a bidirectional hidden converter (BHC)-based three-phase DC–AC conversion for energy storage application. BHC is the new concept to vary an energy storage device voltage into wide range. Hidden converter power loss and power rating are reduced by using zero-sequence injection-based carrier-based pulse-width modulation (CBPWM) strategy. Design/methodology/approach By using this control strategy, a BHC processes only little amount of power during double-stage conversion, mostly during direct or single-stage conversion of the three-phase three-port converter (TPTPC) only processing the maximum power. Findings TPTPC consists of two sets of positive group switches for inversion process, one set of switches is regular inverter switches called vertical positive group switches, and the second set is anti-series switches, which are horizontally connected for direct or single-stage conversion. Originality/value Characteristics, principles and implementations of proposed DC–AC 3Ø conversion system and its PWM strategy are analyzed. Through experimental outputs, the effectiveness and viability of the proposed solutions are validated.
