Abstract

Abstrak Modulasi vector ruang (space vector modulation, SVM) adalah teknik modulasi terbaik untuk kemudi beban tiga fasa seperti motor induksi 3 fasa. Pada paper ini, strategi modulasi lebar pulsa dengan SVM dianalisis secara detail. Strategi modulasi ini menggunakan kalkulasi waktu switching untuk menghitung waktu tegangan vektor yang diterapkan pada beban tiga fasa seimbang. Prinsip strategi modulasi vektor ruang ini disimulasikan dengan perangkat lunak Matlab/Simulink. Hasil simulasi menunjukkan bahwa algoritma ini adalah fleksibel dan cocok digunakan untuk kendali vector lanjut. Strategi switching ini meminimalkan distorsi beban sebaik meminimalkan kerugian akibat jumlah komutasi pada inverter. Kata kunci: distorsi harmonik, inverter, komutasi vetor, modulasi vector ruang Abstract Space vector modulation (SVM) is the best modulation technique to drive 3-phase load such as 3-phase induction motor. In this paper, the pulse width modulation strategy with SVM is analyzed in detail. The modulation strategy uses switching time calculator to calculate the timing of voltage vector applied to the three-phase balanced-load. The principle of the space vector modulation strategy is performed using Matlab/Simulink. The simulation result indicates that this algorithm is flexible and suitable to use for advance vector control. The strategy of the switching minimizes the distortion of load current as well as loss due to minimize number of commutations in the inverter.
