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 […]
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 […]
Sine-Cosine Waveform Generator Circuit
The circuit discussed below is designed to generate precision sine and cosine waveforms, which are perfectly identical with their dimensions, but are 90° out of phase. There are a variety of applications which often demand a couple of sinewave frequencies which are of the identical frequency, but 90° out of phase. Simply put, a sine […]
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 […]
