要約(日本語): The present study addresses to the problem of unbalanced current in parallel connection of distinct output rating automonously controlled UPS. Such problem is due to the lateral reactive current flow between UPS. By means of a root locus analysis, it is observed that the system is robust when the proportional gain of the control equation of the amplitude of the voltage is varied. With a higher value of this gain, the current balance of the system can increase considerably. The present study shows some theoretical considerations as well as the experimental results in which the current distribution is accomplished satisfactorily.
