Abstract

The output voltage of UPS must not vary according to the load variation But the output voltage varies due to the load variation when a PI voltage regulator is used which has inherently a static state error. This paper presents a static-error-free digital PID voltage regulator for an UPS inverter to overcome additionally the voltage unbalance problem in three Phase system as well as the above problem.
