The proposed IC 555 based modified square wave inverter circuit generates accurately spaced PWM pulses which imitates a modified sine wave very closely and thus can be considered as good as its sine wave counterpart design. Here we use two stages for creating the required PWM pulses, the stage comprising the ICs 741 and the […]

How to Calculate Modified Sine Waveform
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 […]
Modified Sine Wave Inverter Circuits using IC 555, 4017, 4049, 4093 and BJTs
When an inverter with square wave AC output is modified to generate a crude sinewave AC output, it is called a modified sine wave inverter. The following article presents interesting modified sine wave inverter designs with exhaustive descriptions regarding its construction procedure, circuit diagram, waveform output and detailed parts lists. The designs are intended for […]
Arduino Modified Sine Wave Inverter Circuit
In this post I will show how to construct a modified sine wave inverter using Arduino. We will explore the methodology of the proposed sine wave inverter and finally, we will take a look at simulated output of this inverter. By Difference Between Squarewave and Modified Squarewave Inverter Inverters saved us from short term power […]
