During summer 2019, Peng Yang conducted his secondment at China Electric Power Research Institute (CEPRI), Beijing. CEPRI has developed the world leading simulation platform for the modelling of power system and power electronics, Advanced Digital Power System Simulator (ADPSS). This meant Peng was fortunate to learn ADPSS and build the models of SiC diodes and SiC MOSFETs, and collaborate with CEPRI’s Dr Qing Mu and Dr Yalou Li. He shared his research findings with supervisors and other PhD students, and attended seminars, such as Prof Timothy Green’s lesson on Power Electronics at Tsinghua University. In addition, he attended the 2019 PhD Asian School on Advanced Power Electronics at Xi’an Jiaotong University; he was later honoured to attend the graduation ceremony at Tsinghua University, where he had received his Bachelor’s and Master’s degrees.
