Abstract :
By analyzing the causes of the flux imbalance in the utility frequency transformer of a sinusoidal wave inverter, a new approach of avoiding flux imbalance is introduced in this paper, that is to apply a DC compensation into the sinusoidal signal. Employing it into 5 kVA UPS proves the practicability of the approach
