Abstract
Power electronics technology is pivotal in transforming how energy is generated, managed, and utilized, in Fourth Energy Revolution. Partial power processing technologies have emerged as a solution to the growing demand for high efficiency and power density in power electronics. By only processing a portion of the total power, partial power converters can achieve higher efficiency and power density than traditional full power converters. Hence, we focus on design methodology, principles, control strategies and practice of applying partial power processing concept to to DC and AC power electronic converters. The mechanisms of partial power processing technology are present first. Topologies of partial power converters based on isolated buck/boost converter, phase-shift full bridge converter and dual active bridge (DAB) converters are compared comprehensively. Then the principle, control strategies and parameters design of high gain partial power converters and step-up/down partial power converters are introduced. Finally, design domains and technical trends are discussed to assist users to maximize the potential of the partial power processing technologies. 
WHO SHOULD ATTEND
This seminar is suitable for intermediate- or advanced-level researchers, engineers and students in power electronics, who are interested in high efficiency power conversion. The attendees should be familiar with the basics of dc-dc and ac-dc converter topologies, power semiconductors and modelling.
