Quasi-Z-Source-Based Isolated DC/DC Converters for Distributed Power Generation
Dmitri Vinnikov,Indrek Roasto +1 more
TL;DR: This paper presents new step-up dc/dc converter topologies intended for distributed power generation systems and describes the operation principles of the proposed topologies and analyzes the theoretical and experimental results.
Journal ArticleDOI
Power converter interfaces for electrochemical energy storage systems – A review
V. Fernao Pires,V. Fernao Pires,Enrique Romero-Cadaval,Dmitri Vinnikov,Indrek Roasto,João Martins +5 more
TL;DR: In this paper, a review of the literature covering the various types of interfaces developed for electrochemical energy storage systems is presented, including standard, multilevel and multiport technology.
Journal ArticleDOI
Step-Up DC/DC Converters With Cascaded Quasi-Z-Source Network
TL;DR: The proposed cascaded qZSI inherits all the advantages of the traditional solution (voltage boost and buck functions in a single stage, continuous input current, and improved reliability) and reduces the shoot-through duty cycle by over 30% at the same voltage boost factor.
Journal ArticleDOI
High-Performance Quasi-Z-Source Series Resonant DC-DC Converter for Photovoltaic Module Level Power Electronics Applications
TL;DR: In this paper, a quasi-Z-source series resonant dc-dc converter is proposed for photovoltaic module-level power electronics applications, where the shoot-through pulse width modulation and phase shift modulation are combined in a single switching stage to realize the boost and buck operating modes.
Journal ArticleDOI
New Shoot-Through Control Methods for qZSI-Based DC/DC Converters
TL;DR: A new modulation technique, pulse width modulation (PWM) with shifted shoot-through, is compared with the conventional PWM shoot- through control method, and the new method reduces switching frequency of bottom side transistors and inherently features partial soft switching.
