Power electronic transformers for AC-AC and AC-DC conversion with reduced number of switches
… for three-phase power conversion (three-phase AC to AC as well as three-phase AC to DC). The goal of this project is to reduce the weight and size of the power converter by replacing the low-frequency transformers with high-frequency transformers (HFTs). The novelty of these proposed topologies …

Supporting the UK distribution networks with power electronic end user voltage regulation
… distribution networks. Studies found that the capacity of the network cannot support the predicted increase in demand due to current limits on the network. To increase the capacity of the network, raising the voltage level of the system was explored. Studies indicated that raising the voltage …
