摘要

传统的无轨电车有几个缺点，不能满足今天的需要。无脱机运行能力和双绝缘设计与目前广泛应用的普通电动客车不兼容是最令人担忧的问题。柴油机双模式运行解决了脱机运行问题，但却破坏了其零排放形象。在过去27年左右的时间里，配备电池和后来的动态充电完全解决了离线运行问题，并很好地服务了市场。本文介绍了一种基于隔离式动态充电电池充电器的新型无轨电车动力系统，说明了如何进一步解决双绝缘问题。目前中国市场上有三种这样的隔离式电池充电器。详细介绍了基于双有源桥拓扑结构的双有源桥拓扑结构。预计，搭载这种新型动力系统的无轨电车将加速在公共交通领域的复兴。

A Dual-Active-Bridge Converter for Novel Trolleybus Powertrain System

Traditional trolleybus has several shortcomings which cannot meet today’s needs. No off-line operation capability and double insulation design incompatible with present wide-spread normal electric buses are most concerned ones. Dual mode operation with diesel engine had solved the off-line operation issue whereas its zero emission image was spoiled. Equipping batteries and later in-motion-charging have in the past 27 or so years totally solved the off-line operation issue and serviced the market rather well. In this paper, a novel trolleybus powertrain system based on isolated in-motion-charging battery-charger is introduced to explain how the double insulation issue is further solved. Three such kinds of isolated battery-chargers are now available in Chinese market. The one based on dual active bridge topology is presented in great detail. It is expected that the trolleybus equipped with such a new powertrain system will accelerate its revival in the public transportation sector.
