Comparison of voltage vector control in various forms of tetrahedron that result from switching combination on three-phase four-leg system active filter is presented especially asymmetric tetrahedron shape which is a projection pqr-coordinate into αβ0-coordinate. Parameter tetrahedrons such as modulation boundary-line, reference vector, switching duration time and duty cycle are described. Duty cycle analysis conducted on the Shen’s model, the Zhang’s model, the Perales’s model and asymmetric’s model are presented. The characteristics results showed that switching combination of each IGBT conductor especially its reviews on the neutral wire. Asymmetric tetrahedron can be proposed as control technique in three-phase four-leg system active filter.

This research analyzes the asymmetric control strategies in multilevel inverters, including asymmetric techniques in space vector modulation of power converters. Modulation parameters such as reference voltage vector (Vref), switching time, and duty cycle are derived in the three-dimensional spatial vector geometry formulation. Asymmetric space vector pulse width modulation (SVPWM) is unique in specifying modulation parameters, has unequal tetrahedron patterns, accompanied by application examples for the upper and lower sector pairs of a tetrahedron. The combination of the switch in the form of an inclined cylinder produces twelve pairs of asymmetric tetrahedrons where the voltage vector positions are in the other twenty-four tetrahedrons. The calculation shows processing dead-time in switching, which is used for current compensation in three-phase power converters.

Power transformation of pqr-coordinate modified by Euler angle rotation method used in analysis of the IGBT active filter circuits as the instantaneous power theory is reviewed. Twice and three times rotation of Euler angle already conducted and produced a matrix transformation different from the Kim-Akagi’s model. Method of Fourier integral in the Voltage Source PWM Converter be done so a harmonics characteristic can be known and may be reduced. Value of Euler angles in frequency domain determined as a carrier harmonic waveforms. This approach is gives slightly different than that has understood so far.

Abstract:. This paper is intended to present a practical set of tone controllers in an audio amplifier using the LM 741 Operating Amplifier (Op.Amp.) Type and is easily obtainable on the market. The discussion is supplemented by the calculation used to determine the value of the resistor filter component R and the capacitor (C) according to the desired cutoff frequency (fc). For practical purposes, drawing a connection pattern on Printed Circuit Board (PCB) is also presented. Since the discussion is still theoretical, it is suggested that once the circuit is built, test the frequency response of the circuit by feeding the audio signal from the AF Generator and draw the Bode diagram to show the frequency response. Keyword: Op.Amp LM741, RC circuit, the frequency response. Abstrak: Makalah ini ditujukan untuk menyajikan perangkat pengatur nada yang praktis dalam penguat audio menggunakan Penguat Operasional LM 741 (Op.Amp.) yang mudah didapat di pasaran. Pembahasan dilengkapi dengan perhitungan untuk menentukan nilai komponenfilter,resistor(R) dan kapasitor (C) sesuai dengan frekuensi cutoff (fc)yang diinginkan. Untuk keperluan praktis, gambar pola koneksi pada papan sirkuit tercetak atau Printed Circuit Board (PCB) juga ditampilkan. Karena pembahasannya masih bersifat teoritis, disarankan agar setelah rangkaian dibangun, lakukan uji tanggapan frekuensi rangkaian dengan memberi isinyal audio yang bervariasi dari Generator AF dan menggambarkandiagram Bode dari tanggapan frekuensinya.Kata Kunci: Op.Amp LM741, rangkaian RC, respon frekuensi.

Anelectric current flow on the neutral wire give raise to harmonics. It is a problem that must be solved one of which is space vector modulation technique. A few voltage vector models have been developed including by Zhang and Perales. In this paper the models are compared to determine reference voltage vector and duty cycle, developed asymmetric’s model based on Akagi theory too. The results show that asymmetric’s model can be proposed as a new technique in space vector modulation.Arus yang mengalir pada kawat netral menimbulkan harmonisa. Hal itu merupakan masalah yang harus diselesaikan salah satunya adalah dengan teknik modulasi vektor ruang. Beberapa model vektor tegangan telah dikembangkan diantaranya oleh Zhang dan Perales. Dalam tulisan ini dibandingkan model-model tersebut dalam menentukan vektor-tegangan referensi dan duty cycle. Dikembangkan pula model asimetri yang berdasarkan pada teori Akagi. Hasilnya menunjukkan bahwa model asimetri dapat diusulkan sebagai satu teknik baru dalam modulasi vektor ruang.

The nonlinear load connected to a three-phase currents source will cause distortion. In order to reduce the distortion, a three-phase active filter system is used. Reduction is carried by the compensation current. The proportional integral (PI) control is often used to control the compensation current. Development of pulse width modulation rectifiers connected to the PI control can produce a pure sinusoidal current source. Compensating current control is also done by Akagi instantaneous power theory approach. Beban nonlinier yang dihubungkan dengan arus sumber tiga fase akan mengakibatkan distorsi. Untuk dapat mereduksi distorsi tersebut digunakan filter aktif sistem tiga fase. Reduksi dilakukan dengan mengkompensasi arus. Dalam pengaturan arus kompensasi digunakan kendali proporsional integral (PI). Pengembangan kendali PI terhubung penyearah modulasi lebar pulsa (MLP) menghasilkan arus sumber sinusoida murni. Pengendalian arus kompensasi dilakukan juga dengan pendekatan teori daya sesaat Akagi.
