I am sure you might have often wondered how to accomplish the correct way of optimizing and calculating a modified square wave such that it produced almost an identical replication of a sine wave when used in an inverter application. The calculations discussed in this article will help you to learn the technique through which […]

Transistor based 3 Phase Sine Wave Generator Circuit
In this post I have explained a very simple 3-phase sine wave generator circuit, using only three bipolar transistors and a few passive components for initiating the desired three phase output. How it Works Referring to the 3 phase sine wave generator circuit we can see three identical transistor stages configured in a cross coupled […]
50 Watt Sine Wave UPS Circuit
The UPS detailed in this article can provide a power output of 50 watts consistently, at 110 volts with a frequency of 60 Hz. The output is fundamentally a sine wave that behaves exactly like standard mains home AC power for the load. An integrated power supply works like a battery charger. Even though the […]
How to Build a 100 Watt, Pure Sine Wave Inverter
The circuit provided in this article shows you a simple way of building a useful liitle inverter that’s easy to build and yet provides the features of a pure sine wave inverter. The circuit can be easily modified for getting higher outputs. Introduction Let’s begin the discussion about how to build a 120 Volt, 100 […]
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 […]
Sine wave PWM (SPWM) Circuit using Opamp
SPWM refers to Sine Wave Pulse Width Modulation which is a pulse width arrangement in which the pulses are narrower at the start, which gradually get broader at the middle, and then narrower again of the end of the arrangement. This set of pulses when implemented in an inductive application like inverter enables the output […]
