1 Introduction
At present, wind-solar complementary systems are developing rapidly, and there are many types of wind-solar complementary controllers, but there are not many systems that can achieve economical reliability, reliability and safety. One of the main reasons is that there is no good control. System. The wind-solar complementary lighting controller works in the outdoor environment and is the core of the wind-solar complementary system. The technical requirements of the controller are high. Under the premise of satisfying the function, the control must be intelligent, reliable and long-lived. The stability is good. After the battery is fully charged, the conventional photovoltaic controller will start the open circuit protection mode, disconnect the charging circuit of the solar panel and the battery, and protect the battery. However, for the wind and solar complementary lighting system, the battery is overcharged. When the fan can not directly open the circuit protection, the unloader is generally used to brake the fan. This paper, through in-depth study of the problems existing in the application of wind-solar complementary lighting system, combined with years of practical experience, proposed a new type of substrate packaging. wind LED lighting controller design method which employs a novel circuit and a special circuit package Style, a good solution to brake failure problems currently existing wind and solar lighting systems appear to improve the reliability of wind and solar lighting system.
2 system composition
As shown in Figure 1, the wind-solar complementary lighting system consists of five parts: wind turbine, solar panel, battery, controller and unloader.
In the whole system, the functions of the controller mainly include the charge and discharge management of the battery, the on/off of the LED light and the full power/half power control. The charging and unloading control of the fan. The protection of the system hardware and software.
