Perancangan Lcl Filter Inverter 3 Fasa Untuk Jenis Switching Msw, Pwm, Dan Spwm Untuk Mereduksi Harmonisa Menggunakan Software Simulink
ABSTRACT
Inverter is a power electronics circuit that is used to convert direct current (DC) into alternating current (AC). To reduce harmonics, you can use a harmonic filter, the filter used is a passive filter in the form of an LCL filter component. Design and installation of passive filters and simulated using MATLAB Simulink R2017b software so as to produce Total Harmonic Distortion (THD) values in 3 Phase Inverters for Switching Modified Sine Wave (MSW) Types, Pulse Width Modulation (PWM), and Sinusoidal Pulse Width Modulation (SPWM). The
generated in the simulation before the passive filter was installed and after the filter was installed on the MSW phase R = 30.39% to 0.18%, phase S = 30.24% to 0.19%, phase T = 30.37% to 0.18%. on the PWM inverter phase R=70.93% to 0.54%, phase S=73.85% to 0.34%, phase T=70.93 to 0.54%. on the SPWM inverter, phase R=5.63% becomes 0.68%, phase S=6.08% becomes 0.42%, phase T=6.08% becomes 0.67%. for
on MSW, PMW and SPWM inverters at phase R=23.55%, 20.18%, 4.68%, phase S=23.35, 5.05%, 21.29% and phase T=23.41%, 21.76%, 5.05%. after installing a passive filter the R phase becomes 0.16%, 0.58%, 0.73%, the S phase becomes 0.17%, 0.41%, 0.51%. phase T to 0.17%, 0.41%, 0.51%. The simulation results that have been carried out by installing passive LCL filters are able to reduce the
and
systems according to IEEE 519-1992 standards.
