Simulation Of Filter And Load Influence On Single Phase Inverter Against Voltage And Current Harmonic

Abstract

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.
