A square wave to Sine wave converter circuit is an important analog circuit that converts square waveforms to sine waveforms. It has a broad spectrum of applications in many different areas of electronics, such as mathematical operations, acoustics, audio applications, inverters, power sources, function generators, etc.
Modified square wave to sine wave equivalent inverter version of the above circuit. Here the lower AMV generate pulses at high frequency whose mark/space ratio can be suitably altered with the help of preset VR1. This PWM controlled output is applied to the gates of the mosfets in order to tailor their conduction into the stipulated RMS value.
Other variations are possible. The sine wave inverter uses a low-power electronic signal generator to produce a 60 Hz reference sine wave and a 60 Hz square wave, synchronized with the sine wave. The reference sine wave goes to the PWM circuit along with a triangular wave that is used to sample the sine wave values to produce a PWM control output.
A filter to turn a squarewave inverter output into sine has to stop 150 Hz, much harder to build, bigger Ls and Cs. Ideally the filter needs to be designed for the specific load, a general purpose output filter is always a compromise. But the compromise is proportionately easier to make with a higher cutoff frequency.
