Overview
What It Does
A comprehensive Python tool that automates AC circuit analysis using phasor methods. Given component values and source frequencies, it computes all node voltages, mesh currents, Thevenin/Norton equivalents, and generates phasor diagrams — then verifies all results against LTSpice AC simulation.

"Built to do exactly what we do by hand in ENR-272 — but 100× faster, with visual output and automatic LTSpice verification."

Key Features
Feature 01
Nodal Analysis Engine
Sets up and solves KCL equations for any n-node circuit using complex matrix inversion and Cramer's rule.
Feature 02
Phasor Diagram Generator
Draws interactive phasor diagrams showing magnitude, phase angle, and lead/lag relationships.
Feature 03
Thevenin / Norton Solver
Finds Vth, Zth, IN, ZN at any terminal pair using open/short circuit phasor analysis.
Feature 04
LTSpice Verification
Exports SPICE netlist, runs AC simulation, and auto-compares Python vs LTSpice results.
Tech Stack

TypeHardware Design
Output5V Regulated
Overview
From AC to Regulated DC
Designed and built a complete regulated 5V DC supply. Full chain: step-down transformer → bridge rectifier → filter cap → LM7805 regulator → output. Every stage hand-calculated, then LTSpice-simulated, then physically bench-tested.

"Every stage was hand-calculated first, simulated in LTSpice, then built and measured on the bench — zero shortcuts."

Design Stages
Stage 01
Transformer
120V AC → 9V AC step-down. Turns ratio selected for peak voltage headroom above regulation dropout.
Stage 02
Bridge Rectifier
4× 1N4007 diodes. Full-wave rectification with theoretical and measured ripple comparison.
Stage 03
Filter Capacitor
2200μF electrolytic. Ripple voltage reduced to <50mV at full 500mA load.
Stage 04
LM7805 Regulator
±5% regulation over 0–1A range. Heat sink sized for worst-case power dissipation.

Overview
Filtering the Signal
Designed LP, HP, and BP RLC filters. For each type: hand-calculated cutoff frequency → simulated in LTSpice → built on breadboard → measured actual frequency response using function generator and oscilloscope.
Results
  • Low-Pass Filter at fc=1kHz — measured -3dB point within 2% of theory
  • High-Pass Filter at fc=5kHz — phase response matched Bode plot predictions exactly
  • Band-Pass at f₀=10kHz — measured Q-factor compared to ω₀/BW calculation
  • All filters validated across 100Hz–100kHz frequency sweep

Role Overview
What I Did
Worked alongside senior engineers designing and testing AC power distribution systems. Primary responsibilities: LTSpice simulation, component selection, technical documentation, and PCB layout review.

"My ENR-272 phasor analysis coursework applied directly from day one — I was running real simulations within the first week."

Key Contributions
  • Simulated 12 AC circuit configurations in LTSpice, cutting prototype testing time by 30%
  • Documented technical specs for 5 power supply units — voltage regulation, load response, thermal
  • PCB layout review in Altium Designer — caught 3 trace clearance violations before fab
  • Presented weekly simulation results to a team of 8 engineers
  • Built a Python script to auto-convert LTSpice output into formatted Excel reports

My Story
From Curiosity to Engineering
I've always been fascinated by how electricity works — from the moment I first wired a simple LED circuit, I knew I wanted to understand the math behind the magic. That curiosity led me to Bunker Hill Community College's Electrical Engineering Technology program.
My coursework in Circuit Design & Analysis II (ENR-272) has been transformative. Learning phasor analysis, AC circuit theory, Thevenin/Norton equivalents, and superposition gave me tools to tackle real engineering problems — not just textbook exercises.

"Every great circuit begins with a clean schematic and a well-written nodal equation."

Outside of academics, I work as a lab assistant helping other students grasp the same concepts. Teaching reinforces understanding — there's no better way to truly know something than to explain it clearly.
