blocks operating in an on-line mode. The rectifier converts the input AC to DC provides the
inverter power source and charges the battery when the line supply is normal. Alternatively,
when the mains supply is disrupted the battery takes over the role to provide the inverter
power without any switching or break in supply. The inverter converts the direct voltage to
AC output for the load use.
