This paper presents a new method that PIR-P dual loop control based on rotating coordinates to improve the output voltage symmetry of inverter under the serious unbalanced load condition.
The experimental results show that the pulse shifting phase control by using software can improve effectively the pulse symmetry and the precision of the d. c. output voltage.
