H-Bridge Sine Wave Inverter Circuit using Arduino

Last Updated on May 24, 2025 by Swagatam 30 Comments

In this article I will explain how we can build an Arduino-controlled H-Bridge sine wave inverter circuit using some easy parts. So this thing will basically convert DC into AC but in a way that looks like a sine wave, right? We are using an Arduino to generate PWM signals and these signals will drive […]

Convert any H-Bridge Inverter to Sine Wave H-bridge Inverter

Last Updated on August 3, 2024 by Swagatam 26 Comments

convert h bridge to sine wave h bridge basic layout

In this post we’ll discuss how to convert any ordinary square wave H-bridge inverter into an almost pure sine wave inverter circuit. Basic Concept The idea is simple, just chop the low side MOSFET gates of the H-Bridge with reverse SPWM (Sinusoidal Pulse Width Modulation) waveform. This will force the low side 50 Hz, or […]

250 Watt Pure Sine Wave Inverter Circuit

Last Updated on January 19, 2025 by Swagatam 32 Comments

250 watt sine wave inverter compressed

The cost and quantity of parts necessary to develop the proposed 250 watt sine wave power inverter circuit is actually much less compared to a noisy square wave switching-type inverter circuit. Only an extra three or four tiny transistors, a some resistors and capacitors, a couple of pots and a small driver transformer are all […]
