Abstract

Penggunaan inverter satu fasa banyak digunakan pada peralatan rumah tangga. Salah satu masalah yang sering timbul dalam proses konversi tersebut yaitu Total Harmonic Distortion (THD). Harmonisa merupakan pembentukan sinyal sinusoida yang nilainya merupakan kelipatan dari frekuensi dasarnya. Untuk mengurangi harmonisa menggunakan metode bipolar SPWM yang berfungsi sebagai pengendali saklar IGBT (Insulated Gate Bipolar Transistor) dalam mengatur tegangan keluar. Sedangkan Filter pasif LCL yang digunakan berupa kombinasi dengan 2 komponen induktor (L) dan kapasitor (C) dirangkai pararel terhadap beban dengan tujuan mengurangi gelombang harmonisa dari gelombang kotak menjadi sinusoida. Dengan menggunakan bipolar SPWM, nilai THDi arus dengan beban R, RL dan RC adalah R 19.10%, RL 14.08% dan RC 21.21%. Untuk THDv tegangan dengan beban R 18.02%, RL 18.02% dan RC 15.50%. Dengan rangkaian filter pasif LCL dapat menekan harmonisa di bawah 5% sesuai dengan standar IEEE 519-1992. Nilai THDi arus dengan beban R 1.53%, beban RL 2.53% dan RC 1.41 % . Untuk THDv tegangan dengan beban R 1.48%, beban RL 1.33% dan RC 2%.

English Abstract

The use of a single phase inverter is widely used in household appliances. One problem that often arises in the conversion process is Total Harmonic Distortion (THD). Harmonics is the formation of a sinusoidal signal whose value is a multiple of its basic frequency. To reduce harmonics using the bipolar SPWM method which functions as a switch controller for IGBT (Insulated Gate Bipolar Transistor) in regulating outgoing voltage. While the LCL passive filter used is a combination with 2 components of inductors (L) and capacitors (C) arranged in parallel to the load in order to reduce the harmonic wave from the box wave to sinusoidal. By using bipolar SPWM, THDi values for currents with loads R, RL and RC are R 19.10%, RL 14.08% and RC 21.21%. For THDv voltage with load R 18.02%, RL 18.02% and RC 15.50%. With a passive LCL filter circuit, it can suppress harmonics below 5% according to the IEEE standard 519-1992. TH value in current with load R 1.53%, load RL 2.53% and RC 1.41%. For THDv voltage with load R 1.48%, load RL 1.33% and RC 2%.
