讲座内容简述

自爱迪生和威斯汀豪斯在电流战中公开对抗DC(直流电)与AC(交流电)以来,直流电(DC)技术在过去120多年中得到了显着改善。固定频率的交流电成为电力的主要形式,这是因为它容易通过高压电力传输来减少损失。然而,电力电子应用中的半导体技术的发展(即所谓的电力电子设备)使得能够以高效率和可控性在DC与DC或DC与AC之间进行电力转换。电力电子技术的发展和潜力推动了电力系统设计和运行的一场革命。在本次讲座中,将重新审视最先进的电力电子技术。通过使用电力电子技术,将强调存在可变频率AC和DC架构的多样化电力转换系统的概念。通过引入用于智能电网的混合AC + DC电力系统和用于载人/无人电动车辆的无线电力传输系统两种情况,以支持这一概念。

Direct Current (DC) technology has been improved significantly over the last 120-plus years since Edison and Westinghouse publicly battled over DC versus AC (Alternating Current) in the War of Currents. Fixed frequency AC became the dominant form of the electric power thanks to its easiness of high voltage electricity transmission to reduce losses. However, development of semiconductor technologies in electric power applications, as known as the Power Electronics, enables electric power conversion between DC and DC or DC and AC with high efficiency and controllability. The enhancement and potential offered by Power Electronics have been driving a revolution of electric power system design and operation. In this Lecture, state-of-the-art Power Electronics technologies in power conversion will be revisited. By virtue of using Power Electronics, the concept of diversified power conversion systems where both variable frequency AC and DC architectures exist will be emphasised. Two cases, the Hybrid AC+DC power system used in Smart Grids and the Wireless Power Transfer systems used in manned/unmanned electric vehicles will be introduced to support the concept.

报告人简介

龙腾博士2016年被任命为剑桥大学讲师。在加入剑桥之前,他曾在GE工作过,他在许多有价值的项目中担任重要角色,例如第一台变压器少电油平台供应船,第一艘大型全电动战舰(45型驱逐舰),第一台电磁飞机弹射示范装置,以及第一艘大型柴油/电动混合动力舰艇(潮级油船)。 龙滕博士领导的团队由2名博士后研究员,4名博士和3名硕士学生组成,并获得工程与物理科学研究理事会(EPSRC),英国创新与行业赞助商超过60万英镑的研究经费。

Dr.Teng Long has been appointed Lecturer at the University of Cambridge in 2016. Prior to joining Cambridge, he has worked for General Electric (GE) where he has led or played an important role in many rewarding projects such as the first transformer-less all electric oil-platform supply vessel, the first large scale all electric warship (Type 45 Destroyer), the first electromagnetic aircraft catapult demonstrator, and the first large scale diesel/electric hybrid vessel (Tide-class tanker). Teng is leading a team formed by 2 post-doctoral research associates, 4 PhD students and 3 MPhil students with more than £600,000 research grants from the Engineering and Physical Sciences Research Council (EPSRC), Innovate UK and industrial sponsors.
