A scalable active compensatory sub-circuit that focuses on and improves the accuracy of the GaN HEMT large signal model is proposed in this letter. Zero error between the simulated and measured dc $I$– $V$ curves is obtained. Combining empirical and table-based models, time-consuming procedures for parameters extraction and optimizing can be simplified. With a normalizing factor introduced, the...
Due to more build-in functions and smaller form factor requirements, mobile devices are required to have better thermal dissipation performance and thinner IC package profile. In this study, a new package which combines Cu pillar bumps with IC backside exposed-die properties is introduced. Compared with solder bumps, Cu pillar bumps can effectively increase substrate circuit layout density and then...
Full converter wind turbines respond somewhat differently than directly-connected machines to short circuit conditions. In distinction with directly-connected machines, full-converter wind turbines have a controlled response to system short circuits. Consequently, they do not behave quite like a voltage behind a reactance, as conventional synchronous or asynchronous machines do. Also, they do not...
