Quasi-Y-Source Boost DC-DC Converter

© 1986-2012 IEEE. In this letter, a new topology called 'quasi-Y-source dc-dc converter' is presented. It inherits all the advantages of the original Y-source converter. In addition, the new topology draws a continuous current from the source, which is definitely more appropriate for most renewable sources. It also has dc-current-blocking capacitors, which will definitely help to prevent the coupled inductor core from saturation. Experimental testing has proven the validity of the proposed network and its application as a high boost dc-dc converter
