A solid state Marx generator with a novel configuration

The new configuration proposed in this paper for Marx Generator (MG.) aims to generate high voltage for pulsed power applications through reduced number of semiconductor components with a more efficient load supplying process. The main idea is to charge two groups of capacitors in parallel through an inductor and take the advantage of resonant phenomenon in charging each capacitor up to a double input voltage level. In each resonant half a cycle, one of those capacitor groups are charged, and eventually the charged capacitors will be connected in series and the summation of the capacitor voltages can be appeared at the output of the topology. This topology can be considered as a modified Marx generator which works based on the resonant concept. Simulated models of this converter have been investigated in Matlab/SIMULINK platform and the acquired results fully satisfy the anticipations in proper operation of the converter

Applications of Dielectric Barrier Discharge Microplasma

Dielectric barrier discharge microplasma is a nonthermal plasma discharge at atmospheric pressure which due to the micrometer size dielectric layer between the grounded and high-voltage energized electrodes enables to drive the device at less than 1 kV. Microplasma is an economical and ecological alternative for conventional technologies used for NOx removal, indoor air cleaning, surface treatment of polymers, biomedical applications such as transdermal drug delivery, or as an actuator. In this chapter, microplasma applications such as indoor air purification, skin treatment for drug delivery, particle removal, and flow control are presented

Sistem Pengisian Baterai Nirkabel dengan Panel Surya Menggunakn Metode Fuzzy

Perkembangan teknologi yang cepat mengarah pada pertumbuhan perangkat elektronik yang ditenagai oleh baterai. Ini membutuhkan sistem pengisian baterai yang sederhana, cepat dan aman. Dalam studi ini, kami telah merancang dan merealisasikan sistem pengisian baterai nirkabel yang dipasok oleh panel surya menggunakan metode kontrol fuzzy. Sistem ini dilengkapi dengan pelacakan matahari untuk menghasilkan daya listrik yang optimal. Selanjutnya, sistem kontrol fuzzy diterapkan untuk menentukan jumlah tegangan pengisian dengan memperhitungkan suhu baterai. Hasil percobaan menunjukkan bahwa sistem pelacakan matahari dapat meningkatkan kinerja panel surya. Sistem selalu mendeteksi suhu baterai dan akan mengurangi nilai tegangan selama proses pengisian saat suhu meningkat. Sistem pengisian baterai ini juga akan secara otomatis mengurangi tegangan pengisian ketika tegangan baterai mendekati nilai maksimum. Sistem pengisian wireless ini menggunakan panel surya 100 WP dengan sistem tracking matahari, ditambah dengan sistem pembangkit sinyal gelombang sinus frekuensi 90 kHz dan 2 buah kumparan sebagai sistem transmisi energi berbasis wireless charging. Sistem ini dapat digunakan sebagai sistem pengisian baterai cepat tanpa mempengaruhi masa pakai baterai. ================================================================================================================================= Rapid technological development leads to the growth of electronic devices powered by batteries. This requires a simple, fast and safe battery charging system. In this study, we have designed and realized a wireless battery charging system supplied by solar panel using the fuzzy control method. This system is equipped with solar tracking to produce optimal electric power. Furthermore, fuzzy control system is applied to determine the amount of charging voltage by taking into account the temperature of the battery. The experimental results show that the solar tracking system can improve the performance of solar panel. The system always detects the temperature of the battery and will reduce the voltage value during the charging process as the temperature increases. This battery charging system will also automatically decrease the charging voltage when the battery voltage approaches the maximum value. This system is expected to be used as a fast battery charging system without affecting the battery life
