VFD Simulator with ESP32 Kit
Build a VFD Simulator That Mimics Industrial Motor Control: ESP32 Three-Phase SPWM Kit
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Step into industrial motor control with this ESP32-powered Variable Frequency Drive simulator. Build a three-phase inverter that mimics real-world VFDs: adjustable frequency and voltage ratio, SPWM control, and current monitoring. Learn power electronics without the cost of commercial hardware.
What You'll Build
You'll solder and connect the ESP32, MOSFETs, gate drivers, current sensor, and OLED onto prototype boards, housed in a DIN rail enclosure. The ESP32 outputs three-phase SPWM to the H-bridge, with adjustable frequency and V/F ratio visible on the OLED. A 24V PSU powers it safely.
What You'll Learn
- Generate three-phase SPWM signals on ESP32 for precise motor-like control
- Design and interface IR2110 high- and low-side gate driver circuits for MOSFET H-bridge
- Implement constant V/F control to maintain torque at varying speeds
- Monitor system health with INA219 current sensing and OLED feedback

Who This Kit Is For
Built for B.Tech EEE and ECE students tackling power electronics projects, Smart India Hackathon participants, and hobbyists at IITs, NITs, VIT, or BITS Pilani. Ideal for final-year project submissions and hands-on VFD learning.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project - accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Use the included QR code to access the AI companion for real-time help with SPWM, gate driver issues, or assembly. WhatsApp support also available.
Is this kit suitable for someone new to power electronics?
This is an advanced project; prior microcontroller and soldering experience is needed. The 24V design is safer than AC, and our AI companion explains key concepts as you build.
Can I drive an actual motor with this VFD simulator?
The simulator outputs low-power SPWM signals for LEDs or resistive loads to demonstrate VFD behavior. It is not designed for continuous motor operation.
Does the kit come with pre-programmed code?
Yes, the ESP32 includes working SPWM firmware. You'll adjust frequency and V/F ratio variables-the AI companion explains every line
ESP32 SPWM drives three-phase H-bridge. Adjustable frequency and voltage ratio simulates VFD operation.
