<span lang="EN-US">This paper deals with voltage tracking control of DC- DC boost converter based on Fuzzy neural network. Maintaining the output voltage of the boost converter in some applications are very important, especially for sudden change in the load or disturbance in the input voltage. Traditional control methods usually have some disadvantages in eliminating these disturbances, as the speed of response to these changes is slow and thus affect the regularity of the output voltage of the converter. The strategy is to sense the output voltage across the load and compare it with the reference voltage to ensure that it follows the required reference voltages. In this research, fuzzy neural was introduced to achieve the purpose of voltage tracking by training the parameter of controller based on previous data. These data sets are the sensing input voltage of the converter and the value of the output load changes. To establish the performance of proposed method, MATLAB/SIMULINK environments are presented, simulation results shows that proposed method works more precisely, faster in response and elimination the disturbances</span>

High Voltage Gain

The interest toward the application of fuel cells is increasing in the last years mainly due to the possibility of highly efficient decentralized clean energy generation. The output voltage of fuel-cell stacks is generally below 50 V. Consequently, low-power applications with high output voltage require a high gain for proper operation. A zero-voltage-switching (ZVS) dc–dc converter with high voltage gain is proposed for fuel cell as a front-end converter. It consists of a ZVS boost converter stage and a ZVS half-bridge converter stage and two stages are merged into a single stage. The ZVS boost converter stage provides a continuous input current and ZVS operation of the power switches. The ZVS half-bridge converter stage provides a high voltage gain. The principle of operation and system analysis are presented. Theoretical analysis and simulation result of the proposed converter were verified.

This work presents a power-electronics based system for renewable energy applications, the system is driven with an only one switch quadratic type boost converter, the discussed converter is based on a stack of switching stages which provide a large voltage gain, a desirable feature for fuel cell generation systems, the converters gain function is the quadratic boost-type converters; furthermore, the topology can be extended. The major benefit of the topology is that there is not a capacitor that sustains the entire output voltage, in contrast to other similar topologies in which there is a capacitor rated to the output port voltage, there is no high voltage capacitor in this system. Experimental verification is presented to confirm the system principles; experiments included a fuel cell emulator that was built and used for the experiments.

Open End Winding

A Dual boost inverter for open-end winding induction motor has been used to improve the power of the induction motor and reduce the number of power switches. However, this configuration still has many disadvantages: the ac output voltage is less than dc input voltage and switches on the same leg turn on at the same time must be avoided. To solve this problem, this paper presents a dual inverter combine boost converter qSBI for open-end winding induction motor configuration that is used for low energies such as solar energy, fuel cell, and battery. With the proposed configuration, the ac output is higher than the dc input without a DC-DC converter and the switches on the same leg can turn on at the same time. Simulation and experimental results will be presented to demonstrate the new features.

Generally, the power generating from the Fuel cell is an electrochemical reaction between H2 and oxygen and it generates electric energy, and the by-product is water vapour. However, the output from the fuel cell systemsis very low, then it becomes necessary to connect more number of cells in series to improve the output. The proposed method electrically divides the fuel cell stack into different sections, and each stack is powered by a direct boost inverter. This paper proposes a concept of high voltage dc-dc boost converter topology for a three phase systemto a typical output voltage from the fuel cell as a stand-alone supply. The main advantage of the proposed boost inverter method include ability to deliver the operations of both boosting and inversion of the power in only one stage, compactness, and economical. The output voltage from the fuel cell is a voltage controlled method and output from the battery is a current controlled method. Analysis, and Simulation are taken from a 1kW prototype.

Mass commercialization of fuel cells (FC) and its usage in transportation requires that the FC technology to be competitive with regard to performance and cost, while meeting efficiency and emissions targets. Therefore, fuel cell output current ripple that may shorten FC lifespan, worsen FC efficiency and reduce the FC output capacity need to be addressed. In this paper, an improved multi-device interleaved boost converter (MDIBC) with novel multiplex controller topology is designed to further reduce the input current and output voltage ripples, without increasing the number of MDIBC switching devices. The Matlab/Simulink behaviour model of the improved MDIBC with novel multiplex controller and conventional MDIBC circuit are developed in the simulation studies. The proposed improved MDIBC design is then compared with the conventional MDIBC and its performance is verified.

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
