Abstract
The concept referred to as a triport of a utility-interactive UPS (uninterruptible power supply) is explained. It has a simple and cost-effective structure and enables a low-cost UPS to be designed with all required UPS features, particularly for single-phase UPSs in the 1-10 kVA power range. The different features in comparison to traditional UPSs are briefly discussed, e.g. voltage and frequency tolerance and utility failures. Results and experience with field operation are illustrated by oscillograms and diagrams
