Double Self-Lift (DSL) Cell Based High Gain Modified Quadratic Converter for Fuel Cell Application

Fuel Cell(FC) has high energy conversion capacity compared to combustion engines. Fuel cells posses low voltage but are very effective in terms of clean energy sources. For wider range of operation FC needs a suitable gain DC-DC converter applicable for fuel cell electric vehicles. Here a high gain double self-lift (DSL) based DC-DC quadratic boost converter (DSL-QBC) has been proposed. The proposed (DSL-QBC) possesses the benefit of low input current stress and low voltage stress across the switch and high output voltage gain. This property of the converter assists in the synchronization of converter with FC for better output. Double self lift network is an inductor capacitor network which helps in uplifting the voltage gain. Double self lift network is integrated with the simple quadratic boost converter to create a hybrid circuit and the detailed analysis of DSL-QBC has been presented. The modification has been highlighted in the figures shown in paper and the results have been verified using Matlab simulation platform. The proposed circuit topology DSL-QBC has been designed for 150 Watts under steady state condition.
