通过在光伏电源和负载之间插入具有适当MPPT控制的智能电源转换器，可以更好地提高太阳能系统的性能。采用智能变流器或功率调节单元（PCU），通过实时阻抗匹配，最大限度地从太阳能电池板中提取功率，并调节光伏电压水平。所提出的PCU配备了基于直接占空比INC算法的智能能量回收技术控制的cuk DC-DC变换器。采用Matlab工具对msx60模块与12V铅酸电池接口的PCU模型进行了验证和有效性验证。无论环境条件如何变化，所设计的系统都能有效地工作，并在瞬态和稳定状态下提供最佳性能。
The performance of a solar energy system can be better by inserting a smart power converter with an appropriate MPPT control between the PV source and the load. The smart converter or the well-known as power conditioning unit (PCU) is employed to maximize the power extracted from the solar panel by real-time impedance matching, and to regulate the PV voltage level. The proposed PCU is equipped with a cuk DC-DC converter controlled by a smart energy recovery technique based on direct duty cycle INC algorithm. The review and validity of the proposed PCU model, which interfaces an MSX 60 module with a 12V lead-acid battery, was performed using the Matlab tools. The designed system works effectively and provides the best performance in transient and stable states, regardless of variations in environmental conditions.
