◼Autonomous Voltage Stabilizer and Power Factor Improvement plant Using Customized Transformer

SUPERVISION: NAHYAN AL MAHMUD (ASSISTANT PROFESSOR)

Designed the framework of a highly efficient system that will produce a reliable continuous output voltage having close to unity power factor.The margin of error of the actual project output was within 1.5 percent of the simulation results.

This project was done in two stages; the first one is building a voltage stabilizer, and the second one is improving the power factor.

Working Principle:

At first, the supply voltage is converted to 12v ac by the center tap transformer.
Next 12v ac is converted to 12v dc by a bridge rectifier.
Bridge rectifier output is limited to less than 5 volts by using a voltage divider circuit.
Divider circuit output is then fed to Arduino which controls the 4 channel relay module based on the supply voltage.
The relay module controls the switching of taps in the tap-changing transformer based on the Arduino signal. When there is a drop in supply voltage, Arduino activates electromagnetic relays which add to more number of turns in the secondary winding, thus giving higher voltage which compensates for the loss in output voltage. When there is a rise in the supply voltage, the reverse happens, and, thus, the voltage at the output side remains almost unchanged. It does not give a constant voltage output but operates the system in a safe voltage range.
Then the total power factor is measured using Arduino UNO which will always provide feedback to control an array of relay and capacitor banks.

Thesis title:

“Performance comparison between Graphene Nano-Ribbon FET & conventional CMOS based on Arithmetic Logic Unit (ALU)"

Abstract

In this thesis project, an alternate device known as Graphene Nano Ribbon (GNR) is used, which stands out as replacements of MOSFETs. Numerous design structures such as Inverter, Adder, 4:1 MUX, Arithmetic Logic Unit (ALU) (using both 10nm & 32nm design rule for single-bit and multi-bit) have been used for the performance analysis. ALU has been designed with the emerging Graphene Nano Ribbon-based FET (GNRFET) at 32nm technology node. The results have been optimized by varying the number of graphene nanoribbons (GNRs). Lastly, the results are compared with a CMOS based ALU to get a realistic idea of its performance compared to the state of the art technology.

Delay, Power & Power-Delay Product (PDP), and energy-delay product (EDP) has been chosen as parameters of comparison between the aforementioned devices. The MOSFET type GNRFET model has been used for simulation purposes on the HSPICE platform.
