中文摘要：
文章从电池快速充电角度出发,基于蓄电池三段式充电策略,提出了一种基于BOOST变流器的多模式直流电源,提高了设备的功率等级、冗余度和可靠性。结合蓄电池三段式充电策略,分析了多模式直流电源的工作原理,藉此构建了系统动态模型。鉴于系统严重的非线性问题,采用了输入输出反馈线性化对系统模型线性化,进而设计了电流和电压的跟踪控制器。搭建了2k W的试验平台,试验发现在单路运行时稳态误差仅有0.3A,即使在稳定性影响最严重的并联运行中单路稳态误差也仅有0.9A,由于采用两路互补对称策略保证了总电流稳态误差在整个充电过程中仅有0.2A,而且总电流在切换瞬态过渡过程中严格无冲击,验证了设备可靠性以及控制策略有效性。
英文摘要：
In this paper, from the perspective of the battery fast charging, based on the battery charged three-step strategy, a multiple model based on the Boost converter dc power supply is proposed, improved the power of the equipment, redundancy and reliability.Combined with the battery charged three-step strategy, analyzes the multi-mode working principle of dc power supply, thus constructs the system dynamic model.In view of the serious nonlinear problems of the system,The system model is linearized using the input/output feedback linearization, and current and voltage tracking controller is designed.Has set up A test platform for the 2 k W, found in A single road running at steady state error of only 0.3 A, even in the worst affected by the stability of the parallel operation of single way of the steady-state error is only 0.9 A, but because the two road complementary symmetry strategy to ensure the total current steady-state error in the whole process of charging only 0.2 A, and the total current in the process of switching transient transition without any impact, validate the control strategy of equipment reliability and validity.
