This project focuses on designing and implementing an AC to DC voltage converter to transform a 230V AC supply into a regulated 6V DC output. The process involves key stages, including waveform generation, full-wave rectification, ripple modeling, filtering, and voltage regulation. Using a full-bridge rectifier, the AC waveform is converted into a pulsating DC signal, accounting for diode voltage drops. A capacitor filter is applied to smooth the ripple and produce a stable DC output. The project also models the performance of the regulated supply under varying load conditions, ensuring minimal voltage drop. MATLAB is used to simulate and visualize the AC, rectified, and filtered waveforms, as well as the voltage regulation curve. This project showcases the principles of rectification, filtering, and voltage regulation, making it applicable for low-voltage DC power supplies in electronic devices.

This project implements an Extended Kalman Filter (EKF) to integrate IMU and GPS data for accurate position estimation, even under challenging conditions like GPS outages and urban noise. The EKF effectively reduces noise, compensates for missing measurements, and maintains stability using IMU predictions. Analysis shows minimal drift during outages and rapid recovery when GPS resumes. The results highlight the EKF's robustness and adaptability for real-world navigation applications.

Active Noise Cancellation System for Power Transformer-Development and Validation
2017
ICCT
Transformer noise is a silent killer that not only causes hearing loss but also life quality degradation. Unlike the other active noise cancellers developed, the precise ANC model on MATLAB was built and verified through laboratory experiments. The simulation model validity is checked at different locations in acoustical field. The results presented here implies that the model developed here has the capability of reducing the noise efficiently.

Design and Simulation using MATLAB/Simulink on Active Noise Control System for Power Transformer
2016
IEEE Xplore
Power transformer noise control is inevitable requirement of time in order to protect people’s health and the environment. As the transformer noise is mainly concentrated in frequency below 1500 Hz so a more precise noise canceller is needed. The following research presents simulation of active noise controller in MATLAB/Simulink based on LMS algorithm. Simulation results are discussed to show that the noise of real power transformer can be reduced through the ANC model presented.
