Distributed power systems are prevalent in telecommunications, networking, and high-end server applications and generally utilize a 48 V bus voltage adopted from the telecom industry. From the 48 V bus, a number of isolated point of load (POL) converters power the end loads, with isolation being required for safety. The traditional distributed power architecture (DPA), shown in figure 1(a), use...

Received Feb 3, 2017 Revised Mar 18, 2017 Accepted May 5, 2017 Dual input dc-dc converters have two input voltage sources or one input source and an energy storage system like ultra capacitor, PV, battery, super capacitors and a single output load. In order to process the power in hybrid energy systems using reduced part count, researchers have proposed several multi-input dc-dc power converter...

Power transformers are facing different stress factors during service. Usually, the effects of DC components superimposing AC phase currents are not taken into consideration. Nevertheless, DC can occur in transmission grids due to different sources. This contribution presents ongoing field measurements which show DC in the range of serval Amperes. Different superimposing DC sources are identifi...

A novel ZVZCS isolated dual series-resonant active-clamp dc–dc converter is proposed to obtain high efficiency. The proposed converter employs an active-clamp technique, while a series-resonant scheme controls the output voltage with the complementary pulse width modulation controller. The active-clamp circuit serves to recycle the energy stored in the leakage inductance or the magnetizing ...

In this paper, a new transformerless buck-boost converter based on ZETA converter is introduced. The proposed converter has the ZETA converter advantages such as, buck-boost capability and input to output DC insulation. The suggested converter voltage gain is higher than the classic ZETA converter. In the presented converter, only one main switch is utilized. The proposed converter offers low v...

<span lang="EN-US">The emerging vehicle-to-grid (V2G) technology has gained a lot of praise in the last few years, following its experimental validation several countries. As result, this is being investigated for standalone houses under name vehicle-to-house (V2H). This latter proposes two-way power transfer between electric vehicles and isolated relying on renewable sources supply. In p...

In this paper, a new cascaded multilevel inverter by capability of increasing the number of output voltage levels with reduced number of power switches is proposed. The proposed topology consists of series connection of a number of proposed basic multilevel units. In order to generate all voltage levels at the output, five different algorithms are proposed to determine the magnitude of DC volta...
