Transformer Optimizer Web App

A Flask-based web application for optimizing transformer designs and running manual simulations.

Pages

1. Optimizer (http://localhost:5000/)

Automatically finds the best tap configuration and input voltage to maximize efficiency.

2. Manual Simulation (http://localhost:5000/manual)

Directly specify tap settings and input voltage to see performance results.

Features

Optimizer Page

• Interactive Sliders for all parameters:

  • Load resistance (5Ω to 10kΩ)
  • Target power output (1W to 100W)
  • Operating frequency (100Hz to 50kHz)
  • Core loss (0W to 5W)
  • Maximum flux density (0.05T to 0.5T)
  • Maximum secondary voltage (10V to 500V)
  • Input voltage range (min/max)

• Real-time Optimization using the transformer optimizer

Manual Simulation Page

• Tap Selection: Choose primary and secondary taps from dropdowns
• Input Parameters: Set input voltage and frequency with sliders
• Load Conditions: Configure load resistance and core loss

Both Pages Display:

• Efficiency (color-coded: green >90%, yellow >80%, red <80%)
• Tap selections with turn counts
• All voltages and currents
• Separate copper losses for primary and secondary
• Flux density and turns ratio
• Input and output power

Installation

1. Install dependencies:

pip install -r requirements.txt

Running the App

python app.py

Then open your browser to: http://localhost:5000

Configuration

Edit app.py and modify the get_default_transformer() function to match your transformer specifications:

• Tap positions
• Core area
• Turn counts
• Resistance per turn for each segment
