Short Description:

-An inverter works by increasing the frequency of the primary power supply from 50Hz up to 20,000 – 100,000Hz. This is done through the use of electronic switches which turn the power on and off extremely quickly (up to 1 millionth of a second). By controlling the power supply in this way, before it enters the transformer, the transformer size can be very significantly reduced.
