| 摘 要： | 为满足我国未来深空探测、星表基地等空间任务电源系统的需求,通过采用基于空间核电源系统的功率因数校正技术来滤除和抑制由发电机产生的谐波,从而提高系统的用电效率。提出一种新型Boost PFC拓扑结构,首先分析变换器的工作原理,之后对工作在连续电流导通模式下的Boost变换器进行建模分析。通过对变换器双环控制中的电压环和电流环进行理论设计和数学推导,从而确定控制环路参数。采用PLECS仿真软件对变换器的控制策略和系统的动态响应进行验证,并实现输入电流对输入电压的零相位正弦化追踪。

| Abstract: | The space nuclear power system is considered as the first option of power system for deep space exploration and planet base establishment. The automated power system is applied to carry out power conversion, regulation and distribution of alternating currents generated from generator so as to meet power demands of different loads of spacecrafts. Power factor correction is able to eliminate and suppress harmonics to improve power efficiency of overall system. A new topology of Boost PFC converter is proposed and operating principle is analyzed as well. State space modeling approach is applied to analyze performance of boost converter based on continuous current mode. The controller parameters are determined through theoretical design and mathematical derivation of voltage loop and current loop. Control strategy and transient response of the converter are verified in PLECS, and zero-phase sinusoidal tracking between input current and input voltage is realized. |
