University Education of Electrical Engineering

• The 1st level of discipline and the 2nd level of
  discipline
• Electrical Engineering is the 1st level of
  discipline

• Postgraduates are educated based on the 2nd level
  classification.
• Specialty means the 2nd level of discipline
• Power electronics and drives is only one of the
  2nd level disciplines of the Electrical
  Engineering

Educations on power electronics

• The end of 1960sThyrister was taken as a
  revolution device. power electronics education
  training was started.
• 1977setup of undergraduates education
• 1981setup of power electronics programs for MS
  and Ph. D
• 2006MS programs105 universities
• Ph.D program25 universities

Estimated graduates 2000 MS/year 250 Ph. D/year
MS program2-2.5 year Ph.D program3-5years

Drives to power electronics educations in China

• Telecommunication development boom since 1990.
  Needs for graduates with PE background. First
  runners Huawei, ZTE
• 1978 3.6 million phones, 1phone/200 persons
• 2001 170million fixed phones, 140 million mobile
  phones, 1phone/4 persons
• Switching power supply industry continuously
  transferred to China for cost reduction. Firstly
  companies from Taiwan, then from Japan, USA, and
  Europe.
• RD centers were increased steadily in China for
  promoting business in China
• With steady economics increase, domestic industry
  needs inverters for increasing productivity and
  energy saving
• Home appliance production are increased quickly
  to provide both domestic market need and oversea,
  which needs power supply, inverter drives and so
  on.

Future drive to power electronics education in
China

• Environment protection. COP3. China is the 2nd
  largest emission country and should take
  responsibility. CO2 and NOx reduction. It will
  drive the renewable energy and energy saving
  technology application.
• Tremendous increase of Car industry has cause
  shortage of oil and pollution problem, city
  transportation problem. Develop public
  transportation such light rail, subway, EV,
  Hybrid Car
• Railway electricity investment is estimated to
  reach USD 240 billion during the years from 2004
  to 2020.
• Deregulation introduce the competition and drive
  the introducing technology to improving power
  quality. HVDC and Ultra high voltage power
  transmission
• Lighting technology
• China will face the power problem with increasing
  the penetration of computer application in homes.
  Energy efficiency display technology and low cost
  and energy saving PC
• Energy saving Appliance

13
Fund Sources

• NSF
• Ministry of Science and technology(863 program,
  supporting plan)
• China development and reform committee
• Provincial Governments
• Companies

Summary

• Almost all universities take power electronics
  as a required course for the undergraduates of
  electrical engineering.
• More than 105 universities have both
  postgraduate programs on power electronics
• Due to limited RD capability of domestic
  companies, universities play important roles in
  RD beside the research.
• Power electronics play more important roles on
  productivity enhancement, energy saving, and
  environment protection in China.
• A large market need to power electronics to
  realize energy saving goal of 2010
• A large market need to power electronics to
  realize renewable goal of 12 in 2020
