Improvement of Energy Efficiency in the Conversion of Electrical Energy by Means of Electronic Converters
View Published Articles →01About This Special Issue
The processes of conversion of electrical energy, and its storage and rational use as other types of energy are a question of continuous study. Under the trends of usage of energy as electrical energy the problem to increase energy efficiency is of great importance.Aims and Scope:
1. AC/DC converters – with near unity power factor, power factor correction, bidirectional
2. DC/DC converters – resonant, bidirectional
3. DC/AC converters – for technology and for renewable energy systems
4. Uninterruptible power supply and systems
5. Converters for Energy Storage Systems
6. Wireless Power Transfer and Power over Ethernet
7. Magnetic, Electrical and Electronic Components for Power Converters
8. Converters for lighting
9. Parallel operation of converters
10. Conversion of other energy to electrical using electronic means
11. Control methods and systems for power converters

Analysis and Investigation of Direct AC-AC Quasi – Resonant Converter
Issue: Volume 4, Issue 6-1, December 2015Pages: 1-7Received: 28 July 2015Accepted: 29 July 2015Published: 29 September 2015DOI: 10.11648/j.epes.s.2015040601.11Downloads:Views:Abstract: The present article reports an analysis and investigation of direct AC-AC quasi-resonant converter. A bidirectional power device, whose switching frequency is lower than the frequency of the current passing through the load, is used for its realisation. A mathematical analysis of the processes has been made and comparative results from computer sim... Show More
