| Abstract: | This paper presents a novel control technique based on distributed-logic-control for the parallel operation of inverters in UPS. The voltage and current characters of voltage source inverters in parallel are also analyzed in detail,as well as the principle of parallel redundant system which can flexibly implement expansion of power system capacities and improve the operation reliability of whole power system.The experimental results of four 3 kVA UPSs based on DSP show that the control strategy is feasible and verified the validity of load-sharing of inverter modules. |
