ABSTRAKTeknologi pengemudian motor dengan efisiensi tinggi serta untuk mencapai empat kuadran operasi menjadi perhatian pada bidang pengemudian elektrik. Matrix converter menjadi alternatif utama konverter drive motor karena keunggulan – keunggulannya. Walaupun matrix converter sebagai drive motor mempunyai kompleksitas tinggi, namun dengan dikombinasikan teknik Indirect Space Vector Modulation (ISVM) dapat menghasilkan kepresisian lebar pulsa modulasi (PWM). Untuk pengendali sistem, diterapkan Fuzzy Supervisory Control (FSC), yang merupakan kendali gabungan, agar kecepatan referensi bisa tercapai. FSC dibandingkan dengan kendali konvensional (PI control) untuk membuktikan keoptimalan performa sistem yang diusulkan. Parameter performa sistem dan Total Harmonic Distortion (THD) dianalisis lebih lanjut. Hasil simulasi menunjukkan bahwa sistem yang diusulkan dapat mencapai Error Steady state (ESS) 0% dan THD lebih kecil.Kata kunci: Matrix converter, ISVM, FSC, motor induksi. ABSTRACTMotor-driving technology with high efficiency and to achieve four quadrants of operation is a concern in the area of electric steering. Matrix converter is the main alternative for motor drive converters because of its advantages. Although the matrix converter as a motor drive has a high complexity, combined with the Indirect Space Vector Modulation (ISVM) technique can produce precision pulse width modulation (PWM). For the system controller, Fuzzy Supervisory Control (FSC) is applied, which is a combined control, so that the reference speed can be achieved. FSC is compared with conventional control (PI control) to prove the optimization of the proposed system performance. System performance parameters and Total Harmonic Distortion (THD) are further analyzed. Simulation results show that the proposed system can reach 0% Error Steady State (ESS) and smaller THD.Keywords: Matrix converter, ISVM, FSC, induction motor.

A dynamic voltage restorer (DVR) based on an AC-AC converter is presented. It is able to compensate different common disturbances in distribution systems, with the purpose of improving the power quality delivered to the users. A prototype has been assembled to test the feasibility of the proposition. In this paper a modulation strategy based on the well known space vector modulation (SVM) algorithm is presented in order to synthesize controllable voltages in magnitude and waveform for compensation purposes. Unbalanced and harmonic distortion conditions in the supply voltages are taken into account. These results positively confirm the design, simulation, assembling, and expectations about the device.

<span style="font-family: &quot;TimesNewRoman,Bold&quot;,&quot;Arial&quot;; font-size: 9pt;">A novel space vector modulation (SVM) method for an indirect matrix converter (IMC) is used to reduce the common -mode voltage (CMV) in the output. The process of selecting required active vectors and to describe the switching sequence in the inverter stage of the IMC is explained in this paper. This novel SVM method used to decrease the peak -to-peak amplitude voltage of CMV without using any external hardware. The other advantage of this SVM method is to reduce the total harmonic distortion of line-to-line output voltage. This new modulation technique is easily implemented through simulation and its results are used to demonstrate the improved performance of the input/output waveforms.</span>

<span lang="EN-US">This paper proposes an ultra- modified symmetric sequence algoritm of space vector modulation of matrix converter. The ultra-modified technique improves the drawbacks of the modified one where it provides a reduction of the total harmonic distortion for both output voltage and output current. Some of the advantages of matrix converter are introduced in this paper. These advantages represented in the output frequency of matrix converter which may be greater than input frequency, controlling rms value of the output voltage and the ability to control the input displacement factor.At the end of this paper simulation and experimental results are introduced which give a presice proof to the proposed algorithms.</span>
