Synchronous rectifiers are widely used in low voltage and high current DC/DC converters to reduce conduction power loss. For popular and reliable topologies, such as Half-bridge, Push-pull and Phase-shifted Full-bridge, the application of self-driven synchronous rectification has design challenges due to the existence of dead times. Existing solutions are not suitable for wide input voltage ran...

Four new topologies of active input current shapers (AICSs) for converters with symmetrically driven transformers (such as half-bridge, full-bridge and push-pull) have recently been proposed. This paper analyzes the extension of the use of these new AICSs topologies to converters with asymmetrically driven transformers. Using some of these topologies, the size of AICS inductors can be reduced a...

Abstract: The three-port converter has three H-bridge ports that can interface with three different energy sources and offers the advantages of flexible power transmission, galvanic isolation ability and high power density. The three-port full-bridge converter can be used in electric vehicles as a combined charger that consists of a battery charger and a DC-DC converter. Power transfer occurs b...

Considering the effects of isolation and high efficiency, a series-resonant DC-DC converter (L-L-C type, with two inductors and a capacitor) has been introduced into a residential photovoltaic (PV) generation and storage system in this work, and a voltage gain curve upwarp drifting problem was found. In this paper, the reason of upwarp drifting in the voltage gain curve is given, and a new chan...

The standard methodology to obtain the model of a power electronic converter is achieved by averaging state-space dynamics converter’s state variables. But average transformer current null over switching cycle in resonant dc-dc converter. Therefore, conventional method not suitable for converters, including phase-shifted bidirectional dual active bridge (PSBDAB) two-time scale discrete-type mod...

In this article, a three winding coupled inductor-based dual active bridge (TWCI DAB) dc-dc converter is proposed. Similar to the current-fed DAB converter, proposed TWCI has small input current ripple and wide voltage range. addition, zero-voltage switching (ZVS) of all switches in full load range under variation can be realized. With magnetic integration structure, size total magnetics reduce...

In this work, the authors introduce a new full-analog front-end for differential capacitance sensors which provides a DC output voltage, directly proportional to the measurand variations. The readout circuit architecture is based on a De Sauty bridge as core of the capacitive sensing whereas the feedback circuitry performs the bridge autobalancing operation by means of changes in a multiplier o...
