I am looking for Doctorate degree which offers me the opportunity to develop new skills while strengthening those I already possess. I am an Electrical Engineering postgraduate with Energy/Power system major. My main strengths are adaptability, dependability and the determination to get a job done. I also learn fast and make few mistakes.

Modelled a micro grid of 3MW (in Matlab/Simulink) in order to study its operation in different states and to evaluate control and protection scheme best suited for micro grids. The micro grid designed was combination of generation system (photovoltaic and wind), storage system (batteries and super capacitor), Converters (DC/AC, DC/DC, AC/DC) and some variable load. After modeling, analysis was also done to have an idea about reliability, security and its economic operation.
Designed and implemented a small photovoltaic system of 100W with a single phase PWM sine wave inverter to provide power to AC loads. Charge Controller was designed to control the over and under charging of battery. To extract maximum solar energy, chronological tracker was designed to keep the panel aligned with the position of sun. Sensors were used to get voltages and current at different points of system and values were sent to remote computer with the help of WIFI to check the status and working of system.
A single phase Pulse Width Modulated (PWM) Sine wave inverter was design and implemented using PIC microcontroller (MC). MC was programmed to give control signal (PWM) to the power stage of inverter (H-Bridge) through the combination of opto-coupler, NPN transistors and MOS-FET gate driver circuitry. A 12V-400V DC-DC step up converter based on Push-Pull topology was designed to give 400V of DC voltage at H-bridge so that inverter’s output can be 220V AC.
Devised a circuitry to control the Speed of small DC motor using feedback loop. This loop consist of microcontroller (as brain or controller), motor (as system) and optical sensor to read current speed of motor and send it back to controller.
