      Abstract: In this work, we made the technical qualification of borofloat 33 glass and also other much cheaper conventional glasses, associated with solid metallization by a broadband characterization method of microstrip technology based on the S-parameters. This made it possible to extract the electromagnetic parameters (dielectric permittivity, tangent loss) necessary for the design and construction of low visual impact antennas. The values of S11, S33, S12, and S34 are then extracted on vector network analyzer (VNA). The data of these measurement results are processed and the values of the loss tangent and the dielectric constant are thus measured with ADS software. We have obtained for the classical glass εr = 6.5 and tanδ = 0.0206; for the microscope glass εr = 6.15 and tanδ = 0.021 and at the end for the borofloat 33 glass εr = 4.5 and tanδ = 0.012.

  • Multi-input Single Stage Three Port DC-AC Converters in Renewable Energy
           Applications – An Overview

      Abstract: Nowadays power electronics three port DC-AC inverters are being broadly used in different devices, such as solar smart mini and microgrid energy systems, standalone smart home energy system. In the recent past, reliability, control technique, efficiency, modularity, and cost-effectiveness are the vital issue for these converters. Many triple port DC-AC inverters have been developed demonstrating by three stages and two stages multiple input single output and single stage multiple input single output inverters. But multiple stages of three port DC-AC inverter is costly and lower efficiency for using a higher number of components at different stages. Research is continued about single stage DC-AC topology to reduce the price and decrease the use of some elements. The study of different multi-input single stage three port DC-AC converter topologies with their control method and application area has been stated in this paper. In this research represents some of the update configurations in the improvement of multi-input and single output triple port DC-AC inverters.
