Technology Reports of Kansai University (ISSN: 04532198) is a monthly peer-reviewed and open-access international Journal. It was first built in 1959 and officially in 1975 till now by kansai university, japan. The journal covers all sort of engineering topic, mathematics and physics. Technology Reports of Kansai University (TRKU) was closed access journal until 2017. After that TRKU became open access journal. TRKU is a scopus indexed journal and directly run by faculty of engineering, kansai university.

The goal of our work is the development of modern control laws for a low-pressure mercury-argon discharge lamp (UV-C lamp) powered by a serial multicell converter for water purification. In the previous article, we presented the multicellular converters series: operation, modeling and control. We also exposed the control modulating cyclic reports which was dedicated to the control of the voltages and the flying capacitors, it was intended to ensure the balancing of the voltages across the switches. Current regulation is done by introducing a classical PI-type regulator synthesized by the pole-placement method, which made it possible to have a good setpoint monitoring despite the presence of the perturbation on the arc current and parametric variations on the arc resistance. After having tested the robustness of the PI regulator vis-à-vis the parametric variations of the arc resistance or the arc current, which are inversely proportional and which vary according to the temperature. The goal of our work is the development of a modern control law for a discharge lamp powered by a serial multicell converter. The first control is the regulation by a traditional PI, but this control has not been very robust. For this, it has been replaced by a fuzzy regulator (Mamdani) to improve the performance of our electronic discharge lamp-Ballast system
Interconnecting a PV inverter system with utility line has been widely adopted to process renewable energy and improve power factor. The PV system combined with the function of the active filter system called PV-AF can be useful for the application in the power distribution system. This paper presents a comparative analysis of performances between Series PV-AF and the proposal PV system under the hybrid structure PV-HF. The two configurations are based three level neutral point clamped inverter to keep a power raised without to oversize the switches and to associate structures in series. It has been observed from the simulation results that the performances of PV-HF are betters especially in the current and power quality
