GaN is enabling a new class of hi-speed power electronics. New topologies, new passives technologies and new high-frequency control ICs are combining with GaN power devices to make high-frequency, high-efficiency and high power densities possible to revolutionize the power electronics industry. GaN’s monolithic integration of hi-speed power FETs with analog, logic and protection circuits is accelerating the adoption of this new class of power systems thru simplified design, reduced bill-of-material costs and shorter development times. GaN technologies and the new GaN eco-system will be reviewed along with a new perspective on the market implications of this hi-speed revolution.

Professor of Power Electronics Systems,
University of Nottingham
The move to more embedded and renewable power generation has led to the start of an increase in the dependency on power converters for the supply and stability of the future electrical energy grid. This talk will explore the applications of Power Electronics in the future grid, from the ‘last mile’ to the connection of GW off-shore wind farms. The converter topologies being developed and demonstrated for a range of applications, including HVDC, micro-grids and solid state sub-stations will explored. The challenges of deploying power converters in these power system applications will be considered and the impact on the future design, regulation and operation of the grid will be explored.
About Pat Wheeler

Variable renewable energy like wind and solar photovoltaics (PV) differ from conventional generation in that they use power electronic converters instead of synchronous generators to connect to electric power grids. At small levels, the power grid can easily handle the integration of variable renewable energy. At much higher levels, there are a number of technical concerns that must be addressed to ensure reliable and economic operations. This presentation will discuss the challenges and solutions to operating power system with high levels of variable renewables and how power electronic interfaces can be used to solve some of these challenges.
