本文针对电动汽车中由牵引系统和辅助系统构成的复杂分布式多变换器结构,研究了恒功率负载(CPL)带来的不稳定性问题。提出了一种圆形开关面技术,旨在提升电动汽车电力驱动系统在恒功率负载下的动态性能与稳定性,优化能量存储系统与驱动单元的交互控制。

English Abstract

Electric vehicles make use of energy storage systems, such as batteries and/or ultracapacitors to power the electric power drive train, as well as auxiliary automotive system for control, safety, and comfort. This relatively complex power structure can be described as a distributed multiconverter system. The constant power behavior of tight-speed controllers in the vehicle's traction system and ti...
