As everyone knows, inverter is equipment that
converts the direct current power to the alternating current. Let us understand
how an inverter works.
In its basic structure, an alternator
comprises of a coil of wire and a rotating magnet fitted near to it. As one
pole of magnet gets attracted to the coil, the current is produced and will
reach to the highest level as the magnet comes closer to the coil and dies down
when the magnet moves away from it. However when the other pole of the magnet
moves towards the coil, the current produced by the coil will flow in the
anti-clockwise direction.
A transformer leads to induction of electric
current in a coil, but in this case, the transformed magnetic field is created
by another coil having alternating current passing through it. The other coil
in which current is flowing itself functions as a magnet because of which the
magnetic field is produced. Depending on
the change in the direction of the current flowing, the polarity of the field
also changes.
In a sine wave inverter, sinusoidal alternating current is produced. In simple
words, sinusoidal current is that type of alternating current that is supplied
by the local electricity grid system to our households. For this current, an
oscillator is required. An amplifying transistor can act as an oscillator if
the some of the resultant amplified power is supplied back to its input as
positive feedback. The oscillator will produce low current power which will be
amplified to produce the desired current output to operate several electronic
appliances at homes or in commercial settings. You need to search for one of
the reputed power inverters manufacturers
to buy the right inverter for your use.
