Abstract :
This paper presents a new control technique which allows the parallel operation of two three-phase UPS modules, this scheme can achieves excellent characteristics both in steady states and in transient states. Experiments are presented to verify the theoretical discussion with two three-phase 60 kVA UPS modules employing the TMS320F240.
