Perbandingan Penggunaan Filter Single Tuned dan Filter Second Order Ntuk Mereduksi Harmonisa pada Motor Induksi Satu Fasa yang Dijalankan dengan Programmable Logic Control

Abstract

Programmable Logic Control (PLC) is a microcontroller made to meet the need of the industrial world. The use of Programmable Logic Control (PLC) as a control device in running one-phase induction motor to do a processing job in the world of industry, where the Programmable Logic Control (PLC) has a non-linear load characteristic generating harmonisa. Therefore, harmonisa arised in the Programmable Logic Control (PLC) can be reduced by using the passive single tuned filter and the passive second order filter that it can meet the standard of IEC61000- 3-2 Class D. The comparison of the use of these two passive filters to reduce the harmonisa by using Matlab/Simulink program as known their results such as by using passive single tuned filter can reduce the total distortion of harmonisa current (THDi) from 116.4% to 16.55% while by using passive second order filter can reduce the total distortion of harmonisa current (THDi) from 116.4% to 17.59%. At every order, the impedance of passive singled tuned filter was less than the impedance of passive second order filter. Greater impedance can cause the filter experience much more heat.
