摘要

提出并实现了一种适用于太阳能发电系统的改进型输入并联输出串联降压变换器(IOBBC)。IOBBC的电压增益高于传统Buck-Boost变换器(CBBC)的电压增益。采用iii型控制器实现了IOBBC的闭环控制。利用所设计的控制器,研究了IOBBC在输入/源电压变化和负载变化等条件下的工作性能。在上述运行条件下,所提出的IOBBC运行情况令人满意。对IOBBC的功率效率进行了测试,发现IOBBC的功率效率达到了91.20%。

An Improved Buck-Boost Converter Suitable for PV Application
In this work, an improved Input-parallel Output-series Buck-Boost converter (IOBBC) suitable for solar power generation system has been proposed and implemented. The voltage gain of IOBBC is higher than the voltage gain of the conventional Buck-Boost converter (CBBC). The closed-loop control of IOBBC has been developed with a Type-III controller. The operating performances of IOBBC have been investigated with designed controller under various conditions i.e., change in input/source voltage and change in load. It is found that the proposed IOBBC has been performed satisfactorily under the aforesaid operating conditions. The power efficiency of IOBBC has been measured and it is found that IOBBC is achieved the maximum power efficiency of 91.20%.
