This paper is aimed to develop a digital signal processor (DSP) for controlling a solar cell and wind-turbine hybrid charging system. The DSP consists of solar cells, a wind turbine, a lead acid battery, and a buck-boost converter. The solar cells and wind turbine serve as the system's main power sources and the battery as an energy storage element. The output powers of solar cells and wind turbine have large fluctuations with the weather and climate conditions. These unstable powers can be adjusted by a buck-boost converter and thus the most suitable output powers can be obtained. This study designs a booster by using a dsPIC30F4011 digital signal controller as a core processor. The DSP is controlled by the perturbation and observation methods to obtain an effective energy circuit with a full 100 W charging system. Also, this DSP can, day and night, be easily controlled and charged by a simple program, which can change the state of the system to reach a flexible application based on the reading weather conditions.
本文旨在开发一种用于控制太阳能电池和风力涡轮机混合充电系统的数字信号处理器（DSP）。该DSP由太阳能电池、风力涡轮机、铅酸电池和降压-升压转换器组成。太阳能电池和风力涡轮机作为系统的主要电源，电池作为储能元件。太阳能电池和风力涡轮机的输出功率会随着天气和气候条件而大幅波动。这些不稳定的功率可以通过降压-升压转换器进行调节，从而获得最合适的输出功率。本研究以dsPIC30F4011数字信号控制器为核心处理器设计了一种升压器。该DSP通过扰动和观测方法进行控制，以获得一个有效能量电路，其充电系统功率可达100瓦。此外，该DSP无论白天还是夜晚，都可以通过一个简单的程序轻松控制和充电，该程序可以根据读取的天气状况改变系统状态，以实现灵活应用。
