This article analyzes, designs, and tests a reconfigurable phase shift full-bridge (r-PSFB) isolated dc/dc converter well suited for a wide voltage operating range. By controlling the auxiliary switches, a series or parallel connection can be realized on the secondary side of the converter. As a result, the r-PSFB converter can operate in an...

This brief presents a 48V-to-1V 10-level dual inductor hybrid converter (DIHC) containing 11 on-chip switches and an off-chip gallium nitride (GaN) switch. Thanks to the 10-level Dickson switched-capacitor (SC) circuit, most of the voltage stress will be taken over by off-chip capacitors, which reduces the voltage stress of each switch to 4.8...

Multiple voltage conversion ratio (VCR) recursive switched-capacitor (SC) dc-dc converters, based on several basic 2:1 converters, are widely used for on-chip power supplies due to their flexible VCRs for higher energy efficiency. However, conventional multiple VCR SC converters usually have one or more 2:1 converters unused for some VCRs,...

In today's highly information-based society, portable smart devices are helping everyone all the time. At the same time, many of them need corresponding power management modules to provide them with stable power from the Li-ion battery. Since different functional modules require different voltage levels, a special DC-DC converter or driver must...

This work proposes an energy harvesting DC-DC converter that is able to efficiently process a wide input power range from 25 mW up to 250 mW, to charge a storage device used in Internet-of-Things (IoT) applications. An interleaved boost-converter topology with two inductors is used to divide the high currents over the two branches, in order to...

Traditional power batteries have been unable to meet the requirements of wireless sensor network (WSN) applications which require battery lifetime and no battery replacement. So, harvesting ambient energy and converting it into electrical energy to power wireless sensors has become an alternative to the traditional power sources. Harvesting...

Climate change has called for an urgent revolution in our energy sector. Concerning energy generation, the use of fossil fuels must be decreased, due to the carbon pollution they produce, and more and more green energy is required to be integrated into the power system. Solar energy represents a valid alternative to generates electricity without...

In this article, we present a 4.5-5.1-GHz fractional-N digitally intensive phase-locked loop (DPLL) capable of maintaining its performance in face of a large supply ripple, thus enabling a direct connection to a switched-mode dc-dc converter. Supply pushing of its inductor-capacitor (LC) oscillator is suppressed by properly replicating the...

The worldwide adoption of Electric Vehicles (EV) has gained momentum in recent years, with more than 30% of all EVs being sold last year. Additionally, a new trend of 800 V battery architectures has appeared to allow for faster charging than the now common 400 V architectures. Future proof charging topologies should, therefore, be able to...

This work proposes an energy harvesting platform that is able to convert power from both DC sources (photo-voltaic cells and TEGs) as well as piezo element sources. It does so only using a single input channel to which a single harvester can be connected. The proposed system is able to differentiate between the two source...

Multiactive bridge converters (MAB) have become a widely-researched candidate for the integration of multiple renewable sources, storage, and loads for a variety of applications, from robust smart grids to more-electric aircraft. Connecting multiple dc ports reduces power conversion stress, improves efficiency, reduces material billing, and...

Trolley bus systems provide modern low-emission public transport for urban areas. The trolley bus demands a peak power at acceleration that is at least 4 times the regular operational power demand of the bus. To provide the acceleration power for a fleet of buses, the substations are inherently oversized. With the excess capacity in the trolley...
