A Voltage Stabilizer
It is also called an automatic voltage regulator (AVR) is an electrical device that is used to deliver a constant voltage output to a load at its output terminals irrespective of any change, or fluctuation in the input i.e. incoming supply.
The square wave inverter
The square wave inverter is a type of inverter that converts solar DC power to AC power. The square wave inverter is simpler in design and more efficient than a sine wave inverter. However, the square wave will not be appropriate for some loads, because the large harmonic content can cause interference.
