Medium voltage power electronic systems play a vital role in enhancing the efficiency, reliability, and flexibility of modern electrical power systems across various applications and sectors. This includes renewable energy integration, HVDC transmission, flexible AC transmission systems (FACTS), energy storage integration, electric vehicle charging infrastructure etc.
Research Scope
Our focus on medium voltage is driven by the emerging opportunities stemming from rapid advancements in digitalization and new power semiconductor technologies. We aspire to provide solutions starting from peripheral circuits needed for medium voltage power devices to the system for an application. We are developing gate drive circuit with protection which has high insulation capability. On system level we aspire to utilizing the components in the most efficient way by developing new topologies, applying new and advance control strategies that are enabled by the rapid developments. All this is supported by utilizing the new measures of simulation.
