| Abstract |
By connecting several UPS inverters in parallel, the reliability or capacity of a UPS system can be improved. To make this parallelization possible, the inverters need some form of load sharing facility. This paper presents a local controller which can be used to connect inverters in parallel. The controller regulates their individual voltage responses, using voltage and frequency droops to share loads and stay synchronized. All measurements are made locally. Simulations and experimental results are presented. |
