In this paper, a new step-upresonant DC-DC converter without an auxiliary switch is introduced. All the switching elements act under zero current switching condition at turn-on and turn-off instants. The proposed converter has a simple auxiliary circuit including an inductor and a capacitor. In addition, the size of the main inductor is considerably reduced because it acts as a resonant inducto...

In this paper, Performance of three-level integrated ac–dc converter with Hysteresis Current Control Technique is presented. The proposed converter combines with the operation of the boost power factor correction and the three-level dc–dc converter. By the implementation of Hysteresis Current controller, the switching sequence is under controlled condition and the output voltage of the proposed...

In some industries applications such as fuel cells, we must use a high voltage gain dc-dc converters for increasing voltage, but, the conventional converters cannot provide the high voltage gain with increasing duty cycle and the converters efficiency is limited by the equivalent series resistances. For this reason, in this paper, a single switch transformerless high step-up dc-dc converter wit...

During the last few years, real time gamma and neutron dosimeters have been developed and semiconductor diodes are frequently used in these dosimeters. Semiconductor diodes are used to charged particle detection. For sensitizing the detector to neutrons, a converter layer is contacted on the front surfaces of them. Incident neutrons interact with the converter and produce charged particles that...

In this paper, a new step-up/step-down AC-AC converter is designed by switched capacitor (SC) techniques. The main features of the proposed SC AC-AC converter are the symmetrical converter topology and the absence of magnetic elements. Owing to the symmetrical converter topology, the number of capacitors in the proposed AC-AC converter is fewer than that in the conventional SC AC-AC converter. ...

In this paper, we propose two novel memoryless reverse converters for the moduli set {2 − 1, 2, 2 − 1}. The first proposed converter does not entirely cover the dynamic range while the second proposed converter covers the entire dynamic range. First, we simplify the Chinese Remainder Theorem in order to obtain a reverse converter that utilizes mod-(2 − 1) operation. Second, we further reduce th...
