Wind-solar complementary power inverter based on intelligent control

This paper dissertates the advantage of wind-solar complementary power supply system from the complementarities of time and region. It describes the development of wind-solar complementary single-phase sine wave power inverter and presents its hardware structure, operation principle, and intelligent control method to design for charging and discharging. Some key techniques such as the circuit topology and operation modes of the master loop, algorithm of the intelligent control charging and discharging and so on, are particularized. The proposed technique was applied in the design of 500W/220V/50 Hz single-phase sine wave DC/AC power inverter integrated with controller. Experiment results show its good steady-state and dynamic response characteristics.
