Electronics Nuclear engineering Uninterruptible power supplies (UPS) design with low frequency transformers for isolation purposes are known to contribute to their bulkiness in terms of size and weight. A UPS with high frequency isolation transformer has been proposed in literature to overcome the problems related to the use of the low frequency transformers. This research involves a simulation study on a single-phase UPS system with design that includes a high frequency isolation transformer.
