Comparative Analysis of Semiconductor Power Losses of Galvanically Isolated Quasi-Z-Source and Full-Bridge Boost DC-DC Converters

Application of PWM Control Strategy on Z-Source Isolated Dual active bridge DC-DC Converters

Benchmark: DC-to-DC Switched-Mode Power Converters (Buck Converters, Boost Converters, and Buck-Boost Converters)

Power electronics represent a large and important class of hybrid systems, as modern digital computers and many other systems rely on their correct operation. In this benchmark description, we model three DC-toDC switched-mode power converters as hybrid automata with continuous dynamics specified by linear ordinary differential equations. A DC-toDC converter transforms a DC source voltage from ...

Studies on Quasi-Z-Source-Based Three-Phase Isolated DC/DC Converter for Distributed Power Generation

Distributed generation is an emerging concept in the electricity sector, which represents good alternatives for electricity supply instead of the traditional centralized power generation concept. Among different distributed generation schemes, fuel cell is expected play a big part due to its inherent advantages. The power density of the quasi-Z-source-based single-phase isolated DC/DC converter...

DC-DC Power Converters

Dc-dc power converters are employed in a variety of applications, including power supplies for personal computers, office equipment, spacecraft power systems, laptop computers, and telecommunications equipment, as well as dc motor drives. The input to a dc-dc converter is an unregulated dc voltage Vg. The converter produces a regulated output voltage V, having a magnitude (and possibly polarity...

Dual-Input Isolated Full-Bridge Boost DC-DC Converter Based on the Distributed Transformers

In this paper, a new two-input isolated boost dc-dc converter based on a distributed multi-transformer structure which is suitable for hybrid renewable energy systems is investigated and designed. With a novel transformer winding-connecting strategy, the two input ports can be decoupled completely, so the proposed converter can draw the power from the two different dc sources, which have low ou...
