Abstract The maximum power of a PV module varies due to changing temperature, solar radiation, and load. To maximize efficiency, PV systems use a maximum power point tracker (MPPT) to constantly extract the highest power that can be produced by a solar panel and then deliver it to the load. The general structure of an…

This thesis describes a method of robust control to determine controller gain. The robust control techniques applied for three-phase dc-ac inverter with an output LC filter. The control law, which employs state feedback and integration of the tracking error, and described in a synchronous 𝑑𝑞 frame and designed approach in discrete-time state space. The gains…

Through study and research, I aim to compile all the projects that EDC and private service providers have already built and are under construction to use this document to find out some important information. Through this document, I can clearly see that the momentum of development in the power sector has increased significantly from year…

The use of fossil fuels is a major source of energy, leading to many problems such as climate change, environmental impact and human health problems. On the other hand, oil and natural gas prices are currently rising steadily, prompting researchers to find new energy sources that could replace them in the future. In comparing biofuels…

Electricity generation and distribution in Cambodia take the form of alternating current, but the electrical loads currently have a direct current supply source. Therefore, the AC/DC converter has been studied and developed, which has two development procedures: Uncontrolled Rectifier and Controlled Rectifier. This thesis describes the LMI-based robust control procedure in a single-phase AC-DC converter…

The Single-Ended Primary Inductor Converter (SEPIC) Using Adaptive Interpolation PI Gain Scheduling. The research aimed at maintaining the output voltage level (Vout) using DC/DC buck-boost of SEPIC type and designing the control algorithm in overcoming the input voltage fluctuation. This was the quantitative research design. The research showed the modeling, design, and Simulation result of…
