This paper presents a new micro-inverter topology that is intended for single-phase grid-connected PV systems. The features of the proposed topology are: (1) eliminating the double-frequency power ripple using small film capacitor; (2) improving the maximum-power-point tracking (MPPT) performance; (3) using long life-time film capacitors, which will improve the reliability of the inverter; and (4)...
In the transformerless photovoltaic (PV) system, the common mode ground leakage current may appear due to the galvanic connection between the PV array and the ground, which causes the safety issues and reduces the efficiency. To solve this problem, a novel inverter topology with switched capacitors is proposed in this paper. By connecting one pole of the PV cell directly to the neutral line of the...
Distributed generation technologies such as photovoltaic, fuel cells and micro turbines are emerging. However, these sources require interfacing units to provide the necessary crossing point to the grid. The cores of these interfacing units are power electronics technologies such as inverters since they are fundamentally multifunctional and can provide not only their principle interfacing function...
Due to the rapid increase in global energy consumption and the diminishing of fossil fuels, the customer demand for new generation capacities and efficient energy production, delivery and utilization keeps rising. Utilizing distributed generation, renewable energy and energy storage can potentially solve such problems as energy shortage and global warming. A promising structure to interconnect these...
This paper applies a dynamical electrical array reconfiguration (EAR) strategy on the PV modules of a grid-connected PV system based on a plant oriented (PO) configuration, in order to improve its energy production when the operating conditions of the solar panels are different, such as in the case of partial shadowing or module failure. The EAR strategy is carried out by inserting a controllable...
