The resultant voltage waveform greater approximates the shape of the sinusoidal voltage waveform than an individual square wave. Most cheap customer electrical power inverters develop a modified sine wave instead of a pure sine wave.
Since early transistors were not accessible with adequate voltage and present scores for some inverter applications, it had been the 1957 introduction from the thyristor or silicon-managed rectifier (SCR) that initiated the changeover to stable-point out inverter circuits.
