新的级联h桥多电平逆变器以提高效率

文摘

有许多局限性提取电力来自可再生能源资源。尽量减少电力需求和短缺我们必须提高功率提取方法。多电平逆变器是用来提取太阳能电池的功率。它综合所需的交流来自多个直流源的输出波形。本文着重于改善多电平逆变器的效率和输出电压波形质量。7级减少开关拓扑结构实现了只有7个开关。基本切换方案和选择性谐波消除实施降低总谐波失真(THD)的价值。选择性谐波消除了波形(SHESW)方法实现消除低次谐波。基本切换方案用于控制电力电子逆变器的开关。提出拓扑适用于任意数量的水平。 The harmonic reduction is achieved by selecting appropriate switching angles. It shows hope to reduce initial cost and complexity hence it is apt for industrial applications. In this paper third and fifth level harmonics have been eliminated. Simulation work is done using the MATLAB software and experimental results have been presented to validate the theory.
