BYPASS THYRISTOR

In case any inverter fault occurs; Bypass thyristors transfer the supply of the load electronically from inverter to Auxiliary

Mains Supply without any interruption.

RECTIFIER

The rectifier generates a very constant DC voltage level by drawing current from the input with a power factor close to 1.

INVERTER

The inverter generates a very constant AC voltage level at the output by using DC voltage source at the rectifier’s output.

BATTERY

Supplies the necessary energy when the mains voltage is not available.
