PWM Inverter Waveform Demo Kit with Arduino Uno
SPWM Inverter Waveform Demo Kit with Arduino Uno: See a Clean Sine Wave on Your Oscilloscope
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
See the theory of pulse-width modulation come to life as your Arduino Uno generates sine-weighted PWM signals driving a MOSFET H-bridge. This kit transforms abstract inverter concepts into a tangible, traceable waveform you can probe and analyse — perfect for science fairs, engineering lab demonstrations, or understanding the heart of solar inverters.
What You'll Build
After assembly, you’ll have a fully functional single-phase H-bridge inverter that outputs a near-sinusoidal AC voltage. Connect your oscilloscope probes across the load and you’ll watch a clean 50Hz sine wave emerge from the switching of four power MOSFETs — exactly as it happens inside a commercial inverter.
What You'll Learn
- Generate SPWM gate signals using Arduino’s timers and compare-match registers.
- Understand the role of IR2110 gate drivers in level-shifting logic signals to high-side MOSFETs.
- Analyse dead-time insertion to prevent shoot-through in an H-bridge.
- Interpret the output waveform on an oscilloscope, relating it to SPWM theory.

Who This Kit Is For
This kit is designed for CBSE Class 11–12 students exploring power electronics in their physics or electronics curriculum, B.Tech ECE/EEE undergraduates needing a hands-on mini-project, and ATL Tinkering Lab mentors demonstrating inverter principles. If you’re preparing for the Smart India Hackathon’s hardware challenges or want something impressive for a college symposium, this kit gives you a complete, safe, and guided experience. It’s also used by first-year engineering students at IITs, NITs, and VIT for their introductory electronics workshops.
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?
Scan the QR code inside the box to chat with the AI build companion; it knows every connection and common pitfall of this SPWM inverter. You can also send a photo via WhatsApp for a human engineer to review.
What oscilloscope do I need? Will a basic USB scope work?
The output is a 50Hz sine wave and switching signals up to a few kilohertz. Any digital or USB oscilloscope with ≥1MHz bandwidth and two channels works, including entry-level Rigol, Siglent, or even pocket DSO models.
Is the 12V side dangerous? Can I probe safely?
The inverter runs at 12V DC with low current, making it safe for bench testing. MOSFETs can get warm, so handle after power-off. The AI companion prompts safe probing practices throughout the build.
Do I need Arduino programming experience?
No. Pre-written, commented Arduino code is included — you just upload the sketch. The AI build companion explains each section if you want to understand the SPWM logic in detail.
Arduino generates SPWM gate signals for a single phase H-bridge. Oscilloscope shows synthesised sine wave.
