There are only small number of studies that focuses on addressing the current harmonic distortion using the most common type of shunt passive filters for a system with a single VFD connected to a 3-phase asynchronous motor that also has a displacement power factor of 1. From IEEE 519, harmonic distortion produced by any users should be addressed given that it is in the accordance with its standard. The main objective of this study is to generate a data that will be used to evaluate the effectiveness of Single-tuned, 2 nd order and 3 rd Order HP, and C-type passive filter in addressing the harmonic current distortion generated by a simulated VFD. Moreover, results drawn from repeated measures and one-way ANOVA suggest that 2 nd order HP filter set at highest reactive power is the best filter when addressing the THD I and individual current harmonic distortion. Second model single-tuned passive filter is the best in addressing current harmonic at tuned frequency. To conclude, first model 2 nd order HP filter is best to considered when the goal is to comply with IEEE 519 standard, and second model single-tuned passive filter is the best consider when the goal is to address the tuned current harmonic.
