Description
hardware flow control. It is an ideal choice in the field of industrial automation.
There is no doubt that power system is a very traditional major in electrical engineering
. After graduation, you are more likely to enter power companies at all levels affiliated to the
State Grid or China Southern Power Grid Co., Ltd. Have you seen that there are many people in
this forum who talk about electricity? The salary is high, so it can be regarded as an iron rice bowl
with guaranteed income regardless of drought or flood; while power electronics and power transmission are a brand-new
major, which is an interdisciplinary subject of electricity, electronics and control theory, involving circuit topology,
automatic theory, analogue, digital and electrical synthesis. Knowledge, practical ability and practical experience determine
the success or failure of the project to some extent. After graduation, students majoring in power electronics generally enter
companies or research institutes, such as the world”s top power electronics companies, such as Emerson, GE, Simens, ABB
, Philips, Oslang, etc., and of course a bunch of domestic companies, generally engaged in switching power supplies and UPS. ,
frequency converter, reactive power compensation, and active filtering, etc. To sum up, if you want to have a good iron job at least for
now, study power systems; if you want to engage in a cutting-edge and challenging sunrise industry, and are not afraid of hardship,
I hope you can study power electronics and electric transmission
after all the hardships. If you don”t get an official position in a power company after three or five years after studying power systems,
your salary at that time may not be as good as that of students who work in power electronics. Power electronics and electric transmission are a brand-new subject. Most of the teachers in China have a background in electrical machinery and may not be able to provide practical guidance.
However, the importance of a mentor is to provide you with broad research resources and lead you into the door of this subject. There are
still some domestic institutions with strong strengths in this subject: the first is undeniably Zhejiang University, with professors Xu Dehong,
Qian Zhaoming, Lu Zhengyu, etc.; the second is Xi”an Jiaotong University, with the highly respected teacher Wang Zhaoan and his two
disciples Liu Jin Jin, Yang Xu; the last one is Yan Yangguang from Nanjing University of Aeronautics and Astronautics and his student
Professor Ruan Xinbo. Of course, the most awesome school in the world is the National Power Electronics Systems Research Center
at Virginia Tech in the United States, where the most awesome Professor Fred.C.Lee Zeyuan Li is located; Of course, the University of
Colorado at Boulder in the United States is not weak either, especially in the direction of digital control of power electronics. Erickson and
Maksimovic, authors of the famous power electronics textbook Fundamental of Power Electronics, are leading figures here. Students who
are interested in engaging in power electronics research abroad can apply to these two schools. In addition, the FREEDM Research Center
of North Carolina State University is also conducting research on power electronics and power electronic devices. There is Professor Alex Q.
Huang [1], the first domestic IGBT manufacturer, and IGBT experts. Inventor Jayant Baliga. However, it is a pity that power electronics is currently
only a technology and cannot be called a scientific subject. That is because a complete and accurate theoretical basis has not yet been formed.
Because if there is no profound theoretical foundation, it cannot be called science. This discipline is currently mainly engaged in the research of
circuit topology and application technology. The current theoretical basis is linear control method and circuit engineering. However, power
electronics should not be regarded as a linear system, because power devices work in a switching state, which is a strongly pathological
nonlinear system. Therefore, it can be said that the current power electronic system based on linear control theory is completely insufficient
and can even lead to some wrong conclusions in some cases. There are currently several research directions in power electronics technology:
