Using of Cascaded Inverter in Photovoltaic System Controlled by Chaos Theory

Using cascaded inverter in photovoltaic system, when number of cascaded unit increases, unbalance usage becomes a problem. Put forward the balance control method of chaos mapping and the method of photovoltaic power inspecting. It can be concluded from the distribute procedure based on random function that the active probability of each photovoltaic power and switching devices is same. The method of Logistic chaos mapping and tent mapping applied to cascaded inverter are proposed. Also propose the idea of inspect photovoltaic power´s stability by chaos theory.
