“…Since the MIC system offers "plug and play" concept, it has become the trend for the future PV system development, however, challenges remain in terms of cost, reliability and stability [5][6][7][8]. As the MIC is most often fed from a single PV module, its typical power rating between 100 and 200 W are also quite common [9][10][11][12][13][14][15][16][17]. Among key system requirements there are: compactness, high reliability and low cost.…”

Abstract. This paper presents a single phase full bridge inverter with coupled filter inductors and voltage doubler for PV module integrated converter (MIC) system. In DC/DC stage, full bridge circuit with high frequency sinusoidal pulse width modulation control is used, and high frequency transformer with voltage doubler rectifier circuit to increase conversional ratio is adopted. Finally, at the conversion end the rectified sinusoidal waveforms is generated. The coupled filter inductors, which are placed in voltage doubler, not only reduce circulating current, which increases efficiency but also make the rectified output sinusoidal waveforms of DC/DC stage as smooth voltage source. In DC/AC stage, the full bridge circuit with line frequency square wave control is adopted to reduce switching losses and control cost. To verify the presented analysis a 100 W prototype single phase 220 VAC 50 Hz inverter output has been constructed and the experimental results are given.

The paper presents a Field Programmable Gate Array (FPGA) based tracker to accurately track the maximum power point (MPP) of a photovoltaic (PV) array. The tracking logic realized on FPGA is based on a modified version of Adaptive Perceptive Particle Swarm Optimization (APPSO) technique. Photovoltaic generation systems use MPP tracker because the photovoltaic array exhibits multiple maxima in the power voltage characteristic under partially shaded conditions. Compared to PSO, the APPSO offers flexibility in the motion dynamics of the particle in the search space through variation in perception radius, number of sampling points per directions, and the number of sampling directions. The APPSO algorithm has been suitably modified to suit to the slight changes in the maximum power point at around the maximum power point. The proposed technique uses only one pair of sensors to control multiple PV arrays. This results in lower cost, higher accuracy and also the algorithm is simple. The implementation of the algorithm on a reconfigurable architecture like FPGA ensures hardware based flexibility in the motion dynamics presented by APPSO. A comparative study is performed to compare the performance of PSO and APPSO with respect to MPP tracking. Compared to PSO that track to the MPP under partial shading conditions and reaches the MPP with 96.41% accuracy, the APPSO can track to the MPP with 97.95% accuracy. The algorithm when realized on an Altera Cyclone EP1C6Q240C8 FPGA consumes 5967 logic blocks.

“…However, this scheme may be affected by chattering across the sliding surface and will involve more complex analysis, which in turn, would need a high-end controller (or digital signal processor) for implementation. Kasa et al [23] have also presented an MPPT scheme in conjunction with a flyback inverter operating in DCM. The PV current information required for MPPT is estimated from the voltage across the decoupling capacitor.…”
