Engineering researchers awarded Best Paper prize for work on “high speed control of power transistor behaviour”

Congratulations to Gwilym Jones, a First Year DPhil student, and Dan Rogers, Associate Professor in the Department’s Energy and Power Group, who have been recognised for their work at the IEEE Workshop on Control and Modelling for Power Electronics (COMPEL 2017) that took place in July in Stanford, California. The Institute of Electrical and Electronics Engineers (IEEE) is the world’s largest technical professional organisation for the advancement of technology.

Best Paper PrizeTheir paper, ‘Investigation of IGBT Switching Energy Loss and Peak Overvoltage using Digital Active Gate Drives’, received the Best Paper award at the conference. The paper examines how the energy loss in power transistors can be reduced by providing a precisely controllable voltage profile to the transistor gate to control its switching behaviour. The IGBT (Insulated Gate Bipolar Transistor) is used widely in high power applications including wind turbine generator drives, photovoltaic energy generation and electric vehicle drive trains. The efficiency gains demonstrated in this work could lead to significant energy savings in a large range of power electronic systems.

Gwilym Jones, who presented the paper at the Conference, said: ‘It was a special experience to attend COMPEL and meet researchers working across a wide range of topics. The feedback I received on our work was helpful, and it was gratifying to learn that the power electronics community are interested in this area. Being given a prize was a rather nice surprise!’
