ABSTRACT:
An uninterrupted power supply unit is provided with a straightforward switch connected between a power source and a load to supply or interrupt a power to a system. The combination of the outputs from two kinds of single phase inverters enables compensating for a variation in the system voltage in the normal condition and to supply a predetermined voltage to the load after decreasing in the system voltage and opening of a straight forward switch.
