Abstract:This paper focus on two control strategies for intelligent UPS. After analyzing the performance of this two control strategies, above two control strategies have applied to 10KVA inverter module. It can be seen from the experiment that the compound control strategy based on PID and repetitive control performs good dynamic and static performances.
