Quasi Y-Source Boost DC-DC Converter

Abstract— Quasi Y-Source Boost DC-DC Converter. 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.The design of front end and/or intermediate step-up DC-DC converter with a continuous input current and wide range of voltage gain is one of the most challenging < Final Year Projects 2016 > requirements faced by many distributed power generation and conditioning systems. It is especially true when intermittent sources like fuel cells, photovoltaic panels, and wind turbines are used [1], [2]. To meet this challenging requirement, various impedance networks have been developed to provide an efficient means of converting power with a wide range of voltage gain. Improvements to the impedance networks by introducing coupled magnetics have also been lately proposed for achieving even higher voltage boosting, while using a shorter shoot-through time [4]. They include the Γ-source [5], T-source [6], trans-Z-source [7], TZ-source [8], LCCT-Z-source [9], high-frequency-transformer-isolated [10], and Y-source [11] networks.
