Research on nanofiber materials is actively done around the world today. Various types of nanofibers have been synthesized using an electrospinning technique. The most important component when synthesizing nanofibers using the electrospinning technique is a DC high voltage power supply. Some requirements must be fulfilled by the high voltage power supply, i.e., it must be adjustable and its output voltage reaches tens of kilovolts. This paper discusses the design and development of a high voltage power supply using a diode-split transformer (DST)-type high voltage flyback transformer (HVFBT). The DST HVFBT was chosen because of its simplicity, compactness, inexpensiveness, and easiness of finding it. A pulse-width modulation (PWM) circuit with controlling frequency and duty cycle was fed to the DST HVFBT. The high voltage power supply was characterized by the frequency and duty cycle dependences of its output voltage. Experimental results showed that the frequency and duty cycle affect the output voltage. The output voltage could be set from 1 to 18 kV by changing the duty cycle. Therefore, the nanofibers could be synthesized by employing the developed high voltage power supply.

Paper Setup must be in A4 size with Margin: Top In the present paper multi carrier sinusoidal modulation technique which is an efficient method of producing control signals is used for a symmetrical inverter with several levels in cascade H Bridge is discussed. The Cascaded H-Bridge performance output levels depend on the DC voltage sources used at the input side. With the help of two DC voltage sources, five level output can be obtained whereas three sources gives levels of seven in output voltage. In this paper, multi-carrier SPWM switching is obtained for switching of multilevel inverter based switches. Two signals are used in this switching method, among which one of the signals is reference which is a low frequency sinusoidal signal and the one is a carrier signal. In case of sinusoidal PWM method of modulation technique, the reference signal is a sinusoidal one and triangular signal can be used as a carrier signal. These types of inverters have the ability to generate inverted output voltage with an efficient harmonic spectrum and reliable output results. This document provides switching signal for H-bridge inverter structure which can improve harmonic performance. The 5-level multilevel inverter is simulated for traditional carrier-based pulse-width modulation (PWM) phase change carrier techniques. The total harmonic performance of the output voltages is analyzed for the two PWM control methods. The performance of the symmetrical PWM CHB is simulated using MATLAB-SIMULINK model. Model results show that THD can be minimized to a limit with level shifted modulation method of the sinusoidal pulse width. The results from the simulations show that the quality of the waveform of the output voltage improves with less loss and with a lower THD.

<p>Abstrak—Bagian penggerak merupakan bagian utama dari sebuah kendaraan. Salah satu bagian dari penggerak adalah <em>Brushless Direct Current Motor</em>(BLDC). BLDC memiliki banyak keunggulan dari motor DC, salah satunya adalah komutasi yang dapat dipisahkan, yaitu komutasi 2 lilitan phasa terhubung dan komutasi 3 lilitan phasa terhubung. Komutasi 2 lilitan phasa terhubung proses awal pergerakannya dimulai dari sedangkan untuk komutasi 3 lilitan phasa terhubung proses awal pergerakannya dimulai dariuntuk setiap perpindahannya secara elektrik. Sehingga daya menengah terjadi saat komutasi 2 lilitan phasa terhubung dan daya maksimum terjadi saat komutasi 3 lilitan phasa terhubung. Dalam penelitian ini respon yang ingin dilihat adalah jumlah RPM pada setiap kenaikan <em>duty-cycle</em> yang diberikan pada motor BLDC, dengan memvariasikan nilai tegangan. Anova merupakan metode keilmuan statistik yang digunakan untuk melihat respon sistem.</p>

Abstrak— Rangkaian multilevel boost converter memiliki prinsip kerja yang sama dengan boost converter konvensional namun rasio tegangan keluarannya lebih tinggi. Dimana tegangan keluaran dari multilevel boost converter ini akan digunakan sebagai catu daya untuk mengendalikan kecepatan putar motor arus searah (MAS). Kemudian akan dilakukan perbandingan antara tegangan keluaran multilevel boost converter dengan boost converter konvensional yang digunakan sebagai catu daya MAS. Pada penelitian ini nilai tegangan keluaran multilevel boost converter saat dihubungkan pada MAS dengan duty cycle 20% yaitu 80,3 volt dan MAS sudah mulai berputar dengan kecepatan 350 rpm. Sementara tegangan keluaran boost converter konvensional sebesar 39,4 volt namun MAS belum dapat berputar pada duty cycle 20% dan tegangan masukan yang sama yaitu 12,3 volt. Kemudian dilakukan penambahan beban MAS pada pengujian multilevel boost converter. Dimana semakin berat beban pada MAS maka torsinya akan meningkat. Dengan demikian perangkat multilevel boost converter dapat digunakan sebagai catu daya MAS untuk kendaraan listrik. Kata kunci: Multilevel boost converter, boost converter, motor arus searah Abstract—Multilevel boost converter circuit has the same working principle with conventional boost converter. Hence, the ratio of its output voltage is higher that will be used as power supply for controlling the rotational speed of MAS. Then, there will be comparison among the output voltage of multilevel boost converter and conventional boost converter which will be used as power supply of MAS. On this research, the output voltage value of multilevel boost converter which is connected with MAS at the duty cycle 20 % is 80,3 volt. Furthermore, it had rotated at the speed of 320 rpm. Meanwhile, the output voltage of boost converter conventional is 39,4 volt. On the contrary, MAS can not rotated at the duty cycle of 20 % with the same input voltage that will be 12,3 volt. Then, it will be added with load of MAS for multilevel boost converter testing. While the load of MAS is heavier, its torque will be increased too. Therefore, multilevel boost converter device can be used as power supply of MAS for electric vehicles. Keywords: Multilevel boost converter, boost converter, direct current motor
