ANew Voltage Sag Compensator with a Gradationally Controlled Voltage

Anew voltage sag compensator with a gradationally controlled voltage inverter which exceeds SEMI
F47 standard has been developed. It consists of a gradationally controlled voltage inverter in which
inverters are connected in series and are charged at different voltages to each other, and which outputs
the sum of each output voltage. This system is small and with an extremely low loss.
