In the motor controller, how is the DC bus support capacitor DCLink in front of the inverter circuit

In terms of the theory and technology of integrated motors, the discipline of "Motor and Electrical Appliances" mainly studies stepper motors, brushless DC motors, and synchronous synchronicators. In terms of the power electronic drive technology of the motor, the structure and control strategy of the electric vehicle and the electric return drive system, and the harmonic suppression technology of the variable frequency power supply were studied. In terms of high-environment and high-reliability motors and electrical appliances, the reliability theory and technology of high-environment electrical appliances, the theory and technology of aerospace electrical appliances, and the reliability design of flywheels for satellite attitude control were studied.

In terms of the theory and application of new electromagnetic mechanisms, special motors, magnetic fluid seals, dynamic balancing of rotating shafts, and electromagnetic forming technologies are studied. Among them, it has a great influence on special motors such as stepper motors and brushless DC motors and aerospace electrical appliances.

Not bad. Study hard and make progress every day.

As long as you put your mind to it, you will be the best.

The golden monkey offers Rui, and the auspicious star is coming.

I wish you good luck in your studies.

Electrical Engineering and Automation (Bachelor's degree).

Electrical Engineering and Automation (Electrical Appliances and Their Control) (Bachelor's degree, four years, Science and Engineering).

Introduction: The major direction of "Electrical Engineering and Control" is one of the advantages and characteristics of the major of "Electrical Engineering and Automation" in our school, and is an important part of the national first-class characteristic major, which mainly cultivates senior engineering and technical talents engaged in the design, manufacture, operation, control and maintenance of electrical and electrical equipment. This major direction has the "Large Motor Electrical and Heat Transfer Technology Engineering R&D Center" jointly established by Harbin Electric Machinery Factory Co., Ltd. and our university, and the professional laboratory is the key laboratory of ordinary colleges and universities in Heilongjiang Province.

Relying on the first-level doctoral degree authorized discipline of "electrical engineering", the provincial first-level key discipline and the postdoctoral research station, this major direction is the authorized discipline of "electrical and electrical appliances" doctoral and master's degrees.

Main courses: This major mainly offers public basic courses, circuits, electromagnetic fields, electrical machinery, power electronics technology, automatic control principles, electrical testing technology, modern electrical control technology, power engineering foundation, computer technology foundation, single-chip microcomputer principle and application and other basic courses and motor design, control motor, modern motor manufacturing technology, motor testing technology, motor control technology, motor motion control, AC speed regulation, new technology of large motor, new energy power generation, Basic courses and professional direction courses such as electrical engineering application software.

Employment direction: can be engaged in the design, development, production, marketing and management of electrical and electrical equipment in the mechanical and electrical equipment manufacturing industry, and can also be engaged in the technical work and management of the operation, control and maintenance of electrical and electrical equipment in the electric power, chemical industry, machinery, transportation and other industries, and can also be engaged in teaching and scientific research in universities and research institutes.

Although Harbin University of Science and Technology is not a 211 university, it has a national key discipline, and the name of this discipline is high voltage and insulation technology.

The discipline of electrical engineering is among the provincial key disciplines.

School rankings don't mean much.

I graduated from Harbin University of Science and Technology last year. No matter how good the school is, the employment is not good, it will not work.

Finish. Harrongbin Institute of Technology is a good school in this second, at least the employment rate is good. The contracted salary is also between 1500 and 3000, and a few people are higher than 3000

Polytechnic is officially ranked seventh or eighth in Heilongjiang. In terms of employment, it is only under the University of Technology and Engineering. Science and engineering employment is good.

Ranked 168th nationally.
