论文摘要
这项研究分析并比较了电动汽车传动系统中两种燃料电池整合方法的传动系统损失。第一个是常规（增强）两阶段系统，而第二个是基于双逆变器的解决方案。动力传动系统损失的每个来源都通过数学方程来描述，并且通过电路模型模拟观察到高阶谐波的影响。与常规方法相比，高速公路和城市驾驶的双逆变器系统可实现5.27％和10.13％的总体能效提高。双重逆变器系统中较低电压额定功率模块的使用和较低的开关频率大大降低了开关损耗并提高了驾驶效率。
This study analyzes and compares the drivetrain losses of two methods of fuel cell integration in electric vehicle drivetrains. The first is a conventional (boosted) two-stage system while the second is a dual inverter based solution. Each source of drivetrain losses is described by mathematical equations and the impact of higher order harmonics are observed through circuit model simulation. The dual inverter system achieves an overall energy efficiency improvement of 5.27% and 10.13% for highway and urban driving compared to the conventional method. The use of lower voltage rated power modules and lower switching frequency in the dual inverter system has significantly reduced the switching losses and improved the driving efficiency.
