Power inverters are the machines that work to transform the
DC current to AC current. Here we shall see the points of difference between
pure sine wave inverters and modified sine wave inverters.
As their names also indicate, the key difference between
these two devices is basically the form of sine wave they produce. A modified
sine wave is a close resemblance of a square wave, which appears as a series of
uniformly spaced squares when it is denoted as a waveform. On contrary to a
square wave, the output of a modified sine wave stays at zero volts for a short
period ahead of switching positive or negative. Quite different from appearing
as a series of squares when expressed as a waveform, a pure sine wave appears
as a succession of even, uniformly spaced mounds and dells. As a result of its
output similar to that of a perfect sine wave, a pure sine wave inverter
supplied by several home UPS manufacturers, supports all sorts of
electronic appliances including specialized and sensitive equipment like audio
equipment, hospital equipment and laser printers. On the other hand, its
counterpart, the modified sine wave model does not support all types of
electronics.
Another significant bass on which these two systems
vary from one another is the energy efficiency that is offered by them. The
modified sine wave model provides less efficiency as compared to the pure sine
wave model. The companies that have taken the green initiatives that comprise
of the energy efficiency, using the pure sine wave inverters that are
transformer-less is the best decision.
