PCB & Circuit Design (KiCad, Proteus)

MATLAB & Engineering Analysis (Simulink, ANSYS FEA/CFD) Designed and simulated buck, boost, single phase and three phase inverter topologies in MATLAB/Simulink to validate DC DC conversion and DC AC conversion behavior for EV applications. Prototyped key power stages in Proteus, including a full wave bridge rectifier with capacitive filtering and Arduino based LED control, to verify hardware behavior before PCB realization. Developed a single sided buck converter PCB in KiCAD (IRF540N, 1N5822, LC output filter), optimizing component placement and high current trace routing to minimize EMI and improve reliability. Designed and simulated a battery monitoring and safety alert system for a two-wheeler EV using Arduino Uno, TMP36 sensor, multi-color LEDs, buzzer, and I2C 16x2 LCD on Tinkercad. Implemented real-time analog sensing and state-based logic to detect low-voltage and overtemperature conditions and trigger coordinated visual (LED) and audible (buzzer) alerts. Calibrated voltage and temperature thresholds and optimized code for stable multi-peripheral operation, gaining hands-on experience with I2C communication, ADC conversion, and EV safety concepts. Developed STM32F401RE firmware in Embedded C to drive LED patterns, dual 7 segment counter, and custom 16x2 LCD characters using GPIO and HAL based drivers.

Implemented ADC based temperature measurement on STM32F103C6 with LM35 sensor and real time 20x4 LCD display, including integer to ASCII conversion and cursor addressing for multi line output. Designed reusable low level drivers (bit banged GPIO, CGRAM handling, union based bit mapping) and configured system clocks, timers, and interrupts; validated all modules via Proteus simulations before hardware deployment. Built a complete EV model (vehicle dynamics, DC motor + gear, tires, FTP 75 driver) to study tractive force, torque

(800 Nm peak), and regenerative braking performance for a 1600 kg vehicle. Designed a DC DC boost converter and single phase inverter, achieving 38 V boosted output with <0.2% ripple and a symmetric 325 V AC waveform for stable power delivery. Implemented lithium ion battery pack modeling with passive cell balancing and BMS fault logic, equalizing cell SOC within 90 s and detecting negative -32 A over discharge for safe shutdown. PROJECTS

Developed a full closed-loop EV model in MATLAB/Simulink integrating battery pack, DC motor with H-bridge controller, vehicle dynamics, and FTP-75 drive cycle for urban driving evaluation. Configured a 320 V, 94 Ah battery and 84 kW DC motor with drivetrain and vehicle body parameters to simulate realistic speed tracking, tractive effort, and range under FTP-75 conditions. Analyzed battery SOC, speed tracking, distance, and energy usage, achieving 90% drivetrain efficiency with regenerative braking and a simulated range of ~34 km over a 41-minute cycle. CFD-Based Heat Exchanger Analysis and Battery Pack Structural Optimization in ANSYS Performed CFD analysis of a shell and tube heat exchanger in ANSYS Fluent (2025 R2) to evaluate temperature, velocity, and pressure drop for EV battery thermal management, reducing hot side temperature from 90 C to 62.05 C. Conducted static, modal, and harmonic structural analysis of an aluminum battery pack enclosure in ANSYS Mechanical, obtaining 0.17463 mm maximum deformation, 10.083 MPa von Mises stress, and safety factor 27.76 under 3 g loading. Correlated natural frequencies (~349–1795 Hz) and harmonic response with operating vibration range to propose weight reduction in low stress regions while maintaining structural integrity.
