摘要

逆变器用于电源提供恒定的电压,电流和频率产生的优点,尽管有变化的负载。然而,逆变器也有缺点。它会产生很大的谐波。为了从逆变器获得高效率,需要一个正弦电压输出和总谐波失真(THD)最小化。影响单相逆变器谐波幅值的因素有负载类型和滤波器是否存在。本研究讨论了带LC滤波器和不带LC滤波器的单相逆变器,采用R和RL串联负载型对电压(V)和电流(I) THD的仿真。LC滤波器和串联RL负载的研究结果表明THD降低。LC滤波器的安装不仅影响谐波抑制,而且影响负载的输出电压和电流。

Simulation Of Filter And Load Influence On Single Phase Inverter Against Voltage And Current Harmonic
The inverter using for power supply provides constant voltage, current and frequency generation advantage although there are changes in the load. However, inverter has weakness too. It will generate large harmonic. To get a high efficiency from an inverter, a sinusoidal voltage output is needed and total harmonic distortion (THD) is minimized. Several factors influence the harmonic magnitude on 1 phase inverter, namely load type and presence of filter. This study discussed about simulation of 1 phase inverter with and without LC filters, using R and RL series load type against voltage (V) and current (I) THD. The study results with LC filter and series RL load indicated THD reduction. The LC filter installation did not only affects harmonic reduction only but also output voltage and current of load.
