【摘要】：提出一种模块化辅助电源系统,可用于对输入串联输出并联(ISOP)或输入串联输出串联(ISOS)主电路系统各模块进行供电。电源采用输入串联输出独立的连接方式,采用这种连接方式的辅助电源系统能够使各模块集成到主电路系统各模块当中。针对ISOI系统所面临的输入均压问题,提出一种新型主从式输入均压控制策略,该策略可以使ISOI系统各个模块在控制上无互联,真正实现了组合系统的模块化设计且控制器设计过程简单。分析该控制策略的稳定性,给出控制器的设计过程并讨论系统各模块输出电压之间的关系。最后通过一台辅助电源样机验证了所提系统结构及控制策略的有效性。
[Abstract]:This paper presents a modular auxiliary power supply system, which can be used to supply power to the main circuit modules of the main circuit system of the input series output parallel connection (ISOPO) or the input series output series (ISOS). The power supply adopts the independent connection mode of input and series output. The auxiliary power supply system with this connection mode can make each module integrated into each module of the main circuit system. In order to solve the problem of input voltage equalization in ISOI system, a new master-slave input voltage equalizing control strategy is proposed. This strategy can make every module of ISOI system have no interconnection in control. The modular design of the combined system is realized and the controller design process is simple. The stability of the control strategy is analyzed, the design process of the controller is given and the relationship between the output voltage of each module of the system is discussed. Finally, an auxiliary power supply prototype is used to verify the effectiveness of the proposed system structure and control strategy.
