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
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 […]
Design your own Sine Wave Inverter Circuit from the Scratch [Tutorial]
In this article I have explained comprehensively regarding how to design a sine wave inverter without any form of coding or complex circuit designs. The included designs are simple yet extremely precise with their sine waveform structure. You might have often felt discouraged, thinking that making a sine wave inverter from the scratch can be […]
9 Simple Sine Wave Generator Circuits Explored
A sine wave generator is actually a sine wave oscillator circuit which generates an exponentially rising and falling sinusoidal waveform. The 9 simple sine wave generator circuits presented in the following article are easy to build, since they incorporate a small number of ordinary electronic components, and can be used for generating an exponentially varying […]
250 Watt Pure Sine Wave Inverter Circuit
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 […]
Digital Step Sine wave Generator Circuit
In this post I have explained how to build a simple yet accurate digital sine wave generator circuit, which is basically an oscillator circuit, enhanced to generate square waves through incrementing steps, which ultimately appears like a stepped sine waveform. By Ron Mackenzy The difference between analogue sine wave generator and digital sine wave generator […]
