- Abstract
To obtain high-quality output voltage, a multi-loop control for UPS inverter is proposed. On the basis of double closed-loop control, repetitive control is introduced to improve total harmonic distortion (THD) of the output voltage. Also, RMS control is introduced to increase steady-state accuracy of the output voltage .Then, the choice of various control programs is discussed and the design of related parameters is analyzed. Experimental results verify the effectiveness of the control method in a 10kVA UPS inverter prototype.
