There has been an increasing interest in transformerless inverter for grid-tied photovoltaic (PV) system because of the benefits of lower cost, smaller volume as well as higher efficiency compared with the ones with transformer. However, one of the technical challenges of the transformerless inverter is the safety issue of leakage current which needs to be addressed carefully. In addition, according to the international regulations, transformerless inverter should be capable of handling a certain amount of reactive power. In this study, a new H6-type transformerless inverter for grid-tied PV system is proposed that can eliminate the threat of leakage current. The proposed topology has also the capability to inject reactive power into the utility grid. Three-level output voltage employing unipolar sinusoidal pulsewidth modulation can be achieved with the proposed topology. The proposed topology structure and detail operation principle with reactive power control are investigated. The relationship among the existing topologies and their reactive power control capability are also discussed. The proposed topology is simulated in MATLAB/Simulink software to initially verify the accuracy of theoretical explanations. Finally, a universal prototype rated 1 kW has been built and tested. The experimental results validate the theoretical analysis and simulation results.

a large amount of electricity is required to support the operation of large manufacturing facilities. Integrating renewable energy into the manufacturing industry reduces the carbon footprint and ensures the long-term sustainability. A key challenge in deploying renewable technology is the power volatility. We propose a solar photovoltaic-based co-generation system to accommodate the electricity needs of semiconductor wafer fabs. The problem is formulated as a stochastic programming model with the goal to minimize the system cost subject to the loss-of-load probability constraint. We compare the renewable energy yield and the system cost at five different wafer fabs in the U.S. Given appropriate tax incentives or equipment subsidies, the study shows that the solar-based energy solution is economically competitive in regions where the overcast days are less than 35% of the year.

“…The most common PV cell technologies used by the manufactures are categorized as Mono-Crystalline (Mono-Si), Polycrystalline (Poly-Si), and thin-film Silicon which has major share of market [7][8][9]. The hybrid structure which uses nanotechnology is another technology and is still used in research applications [10]. Fig.…”

“…However, efforts to reduce costs and increase production costs resulted in producing Poly-Si technology. Accordingly, although Poly-Si is less efficient in comparison with Mono-Si, it replaced Mono-Si technology as the leader of PV technology after 2000 [10]. Moreover, Thin-film technology has gained attraction, mainly because it may reduce the production costs by using lower materials and energy for manufacturing process.…”
