In this proposed study, Transformerless FPGA Controlled 2-Stage PV System is proposed for 3-phase electrical power generation. In this present scheme, to get AC power, power conditioning has been proposed in two stages; namely in first stage maximum power will be extracted and in second stage DC power will be converted into AC power. In this research paper conversion topology has been proposed for...
Solar energy is a renewable and a vast source of primary energy to electricity. PV module is increasingly employed in utilizing the sun's energy for generating electrical energy. The photovoltaic pumping has become one of the most promising fields in photovoltaic applications especially in remote locations. As the output characteristic of a photovoltaic module is nonlinear and changes with solar irradiation...
This paper includes the discussion about the principle of working, performance investigation and simulation of FPGA controlled three-level diode clamped inverter, which is fed by solar PV based DC bus. DC bus was created with the help of solar PV modules and charge controller to feed DC loads directly or AC loads indirectly through proposed three-level inverter. FPGA based three-level inverter was...

This paper is mainly concentrated on the area of charge controller in solar PV power conditioning system. In this paper, a P&O method MPPT charge...
Voltage unbalance crafts various ailing consequences on three phase induction motor (IM). In this paper, various existing methods for the assessment of the performance induction motor under the supply voltage unbalance have been critically reviewed to highlight their shortfalls. It has been revealed that, none of the existing methods are found proficient in the assessment of the performance of IM...
This paper describes the development of Bi-Directional DC-DC converter (BDC) for solar application for charging and discharging the battery based on availability of supply. BDC can operated in two modes i.e., if supply is available at solar PV side BDC acts as boost converter otherwise acts as buck mode. During day time when sunlight is available, BDC acts as a Buck Converter for charging the battery...
The main objective of this paper is implementation of open circuit voltage MPPT controller for solar PV System based on FPGA. MPPT controllers are plays a major role in solar PV system due to its advantage like increases efficiency by tracking maximum power from the panel under all conditions. Among all other existing methods open circuit method is one of the simplest method to draw maximum power...
The identification of appliances has its unique application in detecting fraudulent electricity consumption; this is an important feature for smart meter. The current signature of signal individual and composite appliances has a possible feature set to separate an individual load from the current signature of composite load. We exploited the source signal separation feature of Independent Component...
