As we have done in Power Systems Design Europe, we will be establishing an Editorial Steering Committee

consisting of a small group of senior industry executives from various segments of the Power Electronics

community. The editorial content of Power Systems Design China is in the capable hands of our Chief Editor, Liu

Hong. While the role of our steering committee is to act as an advisory board for Liu Hong to insure the content

of Power Systems Design China technologically leads China’s power electronics, not follow it.

If you are interested in being considered as a member of this committee or would like to recommend a

colleague for consideration, please contact Liu Hong directly at: [email protected]
