Mar 28, 2013 · The discussion revolves around the challenges of using a modified sine wave inverter with sensitive electronics, particularly a computer that requires a stable power supply.
To design a pure sine wave inverter from the scratch, we require the following circuit stages: A basic 50 Hz or 60 Hz inverter circuit. An op amp comparator using IC 741 or by configuring IC 555. Two sets of triangle waveform, one slow (low frequency) and the other fast (high frequency).
But we can also convert square wave inverters to sinewave inverters. A LRC resonant circuit is needed for this. The values determine the output frequency and waveform. For a 50Hz 150V square wave output to become 230V 50Hz sine-wave, you need the above circuit connected to the output of the inverter.
A sine wave inverter is a device which converts battery power into a 220 V AC or a 120 V AC sine wave output. There are 3 basic types of inverters: square wave inverter, modified sine wave inverter and a pure sine wave inverter. The voltage waveform output from a square wave inverter is square wave.
For a 50Hz 150V square wave output to become 230V 50Hz sine-wave, you need the above circuit connected to the output of the inverter. 100mH (0.1H) inductor, make sure you get high amperes rating ones. 27Ohm resistor, get atleast 50Watts resistor for a 250Watts inverter.
When a pure sine wave inverter isn’t necessary if you have electronic devices that use rectifiers to convert AC to DC, then you probably don’t need a pure sine wave inverter. However, most electronic devices run just fine on a modified sine wave. How do you turn a square wave into a sine wave?
There's pretty easy to make square wave inverter circuit in the internet. But to run most load like fan, TV, etc you need to have a sine wave inverter. Making sinewave or near-sinewave inverter is more complex and costly. But we can also convert square wave inverters to sinewave inverters. A LRC resonant circuit is needed for this.
