New step-up DC/DC converter with high-frequency isolation
TL;DR: In this article, a new step-up DC/DC converter topology with high-frequency isolation was proposed for residential fuel cell power systems in contrast to traditional voltage source converters, which utilizes the impedance network represented by a combination of two inductors and two capacitors.
Four Novel PWM Shoot-Through Control Methods for Impedance Source DC-DC Converters
TL;DR: In this article, the authors proposed four novel pulse width modulation (PWM) shoot-through control methods for impedance source (IS) galvanically isolated DC-DC converters.
Proceedings ArticleDOI
Control of Ultracapacitors Energy Exchange
TL;DR: In this paper, the basic concept of how ultracapacitors could be used in tramways is introduced and three different regulators, proportional (P), integration (I), and the combination of both (PI) are tested and compared to each other.
Proceedings ArticleDOI
Impact of component losses on the voltage boost properties and efficiency of the qZS-converter family
Dmitri Vinnikov,Indrek Roasto +1 more
TL;DR: In this article, a steady state analysis of three main topologies operating in the continuous conduction mode is presented, and the impact of losses in the components on the boost conversion efficiency is analyzed.
