Resumen:
A droop control strategy to achieve parallel operation of single-phase inverters for UPS applications is proposed in this work. This strategy is based on multipleresonant controllers designed to comply with performance specifications given by IEC62040-3. In order to reduce the circulating current between the parallel connected inverters, the inverters output impedances must be increased. For this purpose a damping factor in the resonant controller tuned at the fundamental frequency is proposed. A design criteria for this damping factor is proposed based on a state-space model of the whole UPS system. Experimental results are presented to validate the proposal.
