In modern society, electrical energy is as indispensable as water and air. Power electronics technology is based on the switching operation of power semiconductor devices, and not only converts the form of this electrical energy, i.e., voltage, current, and frequency, into the required form, but also controls it with high speed and high precision. Power electronics technology is not only a key technology for energy conservation, but is also on the verge of becoming a comprehensive power management technology. In the Electrical Energy Conversion Laboratory, we are studying power conversion and control technologies that are widely applied to the generation, transmission, and utilization of electrical energy. In addition, EMI/EMC of power converters is also studied.
