摘要
提出了一种单相交流电源的基波谐波检测方式。单相逆变器产生了大量的谐波,直接影响电能质量。基于正交变换理论提出一种改进型方法,可以精确检测基波和谐波。从原理上进行了分析,利用Matlab仿真软件进行了仿真验证,结果表明该方法有效可行。
An improved quick detection method for fundamental wave and harmonics based on orthogonal transformation theory was presented. Single-phase inverter produces a large amount of harmonics, which directly,affects the quality of electric energy. This paper proposed an improved method based on orthogonal transformation theory ,which can fully detect the fundamental wave and harmonics. The principle was demonstrated. The simulation results show that the improved detection method is valid and feasible.
