Abstract
DC networks for residential consumers have gained attraction in recent years, primarily due to building-integrated photovoltaics and increasing electronic loads coupled with the decreasing prices of DC appliances. The purpose of this project is to construct a prototype DC electrified house that can be usable in rural electrifications. More specifically, this project focuses on the development and construction of an efficient DC powered house by minimizing the losses in the conductor, cable length and total cost of the system and also to verify that both the cost and losses can be minimized with respect to conventional type solar powered AC system, as the inverter loss is omitted in the above system. In this project both simulation and hardware implementation both AC and DC powered houses are done. The results of this project serves as a proof that, the solar powered DC electrification is economically feasible compared to the conventional AC solar powered houses

Abstract
In this paper a Unified Power Quality Controller is connected to a test system with harmonics and voltage variations creating sags and swells in source and load voltages. The UPQC is supported with PVA connected at the DC link injecting active and reactive powers to the grid. Individual controllers are modelled for shunt and series converters with feedback from the source and load voltages and currents. Both the converters work in synchronization to the source voltage with SRF controller using sinusoidal PWM technique. An MPPT is also used for magnitude generation of the reference current. For further improvement in the model the conventional sinusoidal PWM is replaced with space vector PWM reducing the harmonic content in the source voltages and currents. The design is modelled in MATLAB Simulink environment with graphs generated with respect to time.

Abstract
In this paper a micro grid is introduced with PVA and battery connected to DFIG for energy sharing. This paper presents a green energy solution to a microgrid for a location dependent on a diesel generator (DG) to meet its electricity requirement. This microgrid is powered by two renewable energy sources namely wind energy using doubly fed induction generator (DFIG) and solar photovoltaic (PV) array. The extraction of maximum power from both wind and solar, is achieved through rotor side VSC control and bidirectional buck/boost DC-DC converter control, respectively. The microgrid is modelled and simulated using Sim Power Systems tool box of MATLAB, for various scenarios such as varying wind speeds, varying insolation, effect of load variation on a bidirectional converter and unbalanced nonlinear load connected at point of common coupling (PCC). The DFIG stator currents and DG currents, are found balanced and sinusoidal. The model is further updated with DC-DC boost converter connected

Abstract
Wide-bandgap (WBG) semiconductor materials such as silicon carbide (SiC) and gallium-nitride (GaN) allow higher voltage ratings, lower on-state voltage drops, higher switching frequencies, and higher maximum tempera- tures. All these advantages make them an attractive choice when high-power density and high-efficiency converters are targeted. Two different gate-driver designs for SiC power devices are presented. First, a dual-function gate-driver for a power module populated with SiC junc- tion field-effect transistors that finds a trade-off between fast switching speeds and a low oscillative performance has been presented and experimentally ver- ified. Second, a gate-driver for SiC metal-oxide semiconductor field-effect transistors with a short-circuit protection scheme that is able to protect the converter against short-circuit conditions without compromising the switch- ing performance during normal operation is presented and experimentally validated. The benefits and issues of usin
