“…As it is obvious, the switching period must be greater than the sum of the resonant transition times, which are given in (6), (10), (16), (18), (20), (26), (29), (36), (39), (42) and (44). In this paper, the sum of the resonant transition times is assumed as equal as the 15% of the switching period, T. Hence, the maximum value of the switching frequency is as follows:…”

In this study, a new interleaved full soft switching DC-DC boost converter with a high power reliability is proposed. To achieve soft switching, a simple auxiliary circuit consisting of one switch, one diode, one inductor and two capacitors is employed in each single-phase DC-DC boost converter connected in parallel. All switches and diodes, including main and auxiliary ones, operate under soft switching conditions. These soft switching conditions consist of zero voltage and zero current switching (ZVZCS) for all switches and diodes at switching transitions except the output diodes, which turn off only with zero current switching. The soft switching technique used in this study decreases power losses which leads the converter to have higher efficiency and reliability. Also, the auxiliary circuit is located out of the main power path preventing high voltage and current stresses on the switches. In this study, operational modes analysis, design procedure, power reliability evaluations and laboratory prototype results with switching frequency of 20 kHz, input voltage of 48 V and output power of 40 W are presented. T R component temperature rise above T AO R sng , R int single-phase and interleaved converters power reliabilities, respectively

“…Bir güç dönüştürücü devreden beklenilen yüksek verim, düşük maliyet ve küçük hacimdir [4]. Sert anahtarlama teknikleri kullanılan bir güç dönüştürücüde yüksek anahtarlama frekansı anahtarlama kayıplarının artması nedeniyle verimin düşmesine, yüksek Elektromanyetik Girişime (EMI) ve anahtarlar üzerinde stres oluşmasına neden olur [1, 5,6]. Sert anahtarlama teknikerinden kaynaklanan bu olumsuzlukları azaltarak anahtarlama frekansının artırılmasının bir yolu ise rezonans güç dönüştürücüleri kullanmaktır [5,7].…”

D sınıfı eviriciler geniş kontrol aralığına sahip olmaları, az sayıda g&uuml;&ccedil; anahtarı ve anahtar s&uuml;r&uuml;c&uuml; devre elemanları gerektirmeleri ve y&uuml;ksek g&uuml;&ccedil;leri kontrol edebilmeleri sebebiyle g&uuml;n&uuml;m&uuml;zde bir&ccedil;ok uygulamada kullanılmaktadır. Bu &ccedil;alışmada D sınıfı rezonans evirici analizi Runge-Kutta algoritması ile ger&ccedil;ekleştirilmiştir. Yapılan analizin sonucunda evirici akımı ve gerilimi, kondansat&ouml;r gerilimi gibi devre parametrelerine ait grafikler &ccedil;izdirilmiştir. Aynı devre parametreleri MATLAB Simulink &uuml;zerinde yapılan benzetim &ccedil;alışmasında da tekrarlanarak sonu&ccedil;lar karşılaştırılmıştır ve Runge-Kutta algoritmasının doğruluğu ortaya konulmuştur.

“…Hence the hard switching dc-dc converter limits the energy transfer efficiency. In order to overcome these drawbacks, the soft switching techniques are employed and different methods of soft switching were proposed in recent literature [1][2][3][4][5].

This paper investigates a modified simple soft switching dc-dc converter for low power applications. This simple topology uses an auxiliary switch, an inductor and a capacitor to operate the converter without switching losses. The efficiency of the converter is improved by transferring the energy that would be dissipated during the switching to the load. The main switch turns-on with zero current switching (ZCS) and turns-off with zero voltage switching (ZVS), while the auxiliary switch turns-on and turns-off with zero voltage switching (ZVS). The detailed theoretical analysis and the design equations are described. In addition to that, the analysis of proposed converter is demonstrated by both simulation and experimental results for effectiveness of the study.
