hardware flow control. It is an ideal choice in the field of industrial automation.

technology: All information systems and communication equipment require the use of switching power supplies, ranging from various portable digital products to
the various modern flat-panel TVs to servers. systems, communication base station rooms, and various aviation facilities, etc.; The
application of power electronics technology in power
systems: such as various harmonic compensation, active filtering devices, etc., as well as the continuously developing uninterruptible
power supply equipment (UPS), the drive and control system of electric vehicles, and the energy-saving drive of motors, such as For various
frequency converters (including variable frequency air conditioners), under the current energy shortage situation,
power electronics technology is the most critical technical element for the application of solar energy, wind energy and various renewable
energy sources. You can first learn about this subject from some professional journals. Domestic ones include “Chinese Journal of Electrical
Engineering”, “Journal of Electrical Technology”, “Power Electronics Technology” and “Journal of Electrical Technology”, and international ones
include IEEE”s “Power Electronics” , conferences include IEEE”s APEC, PESC, ECCE, etc.
Based on many years of actual research and development experience in switching power supplies, I think the basis of this direction is: the first is
control theory; the second is circuit knowledge; the third is also very important, analog electronics. Of course, today’s power electronics Digital control is
a very important development direction, and the digital control technology of single-chip microcomputer and DSP will
also occupy a very important position. But in reality, for many people engaged in power electronics research and development, it is simply not enough to
learn “power electronics technology” because it is difficult to understandControl loop design of power electronic systems; but people who study control
have no way to start, because they probably don’t know how to combine control and circuit topology, or even don’t understand the working principle of the
circuit at all. In fact, what this discipline lacks the
most is multi-disciplinary talents. Many people engaged in control do not understand electronic and electrical theory; those engaged in electronic and
electrical do not understand the basics of control and do not understand digital control technology.
