Abstract

Penapis Kuasa Aktif (PKA) terkenal dengan kebolehannya memampas harmonik arus dalam talian kuasa. Pelbagai jenis konfigurasi PKA telah dicadangkan dalam tempoh beberapa dekad yang lalu, tetapi jarang terdapat artikel yang mempertimbangkan kebolehan PKA meningkatkan tahap struktur pembinaannya. Artikel ini akan membandingkan operasi penyongsang biasa yang berbentuk H dengan Penyongsang Pelbagai Aras Struktur Bermodul (PPASB) yang dikawal oleh kaedah kawalan Pengamilan Disatukan Berfrekuensi Tetap (PDBT). Kelebihan struktur penyongsang baru tersebut dapat dipertambahkan peringkatnya untuk kegunaan kuasa yang lebih tinggi. Ciri–ciri setiap penyongsang tersebut akan dibincangkan dan keputusan simulasi berdasarkan MATLAB/SIMULINK juga dicatatkan. Kata kunci: Penapis kuasa aktif, penyongsang–H, penyongsang pelbagai aras struktur bermodul, pengamilan disatukan berfrekuensi tetap, pemampasan harmonik Active Power Filter (APF) is well known for its capability of compensating current harmonics in power lines. Vast varieties of APF configurations were proposed for the past few decades, but not many papers consider the expansion capability of APFs. This article presents the comparison of performance for the conventional single level H–bridge inverter and Modular Structured Multilevel Inverter where both are controlled by Unified Constant-Frequency Integration (UCI) control scheme. The latter inverter structure is more flexible to be expanded to suit higher power application. Characteristics of each topology are discussed and the simulation results based on MATLAB/SIMULINK are presented. Key words: Active power filter, H–bridge inverter, multilevel inverter, unified constant–frequency integration control, harmonic compensation
