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.
