Abstract
In this paper, a boost converter with generalized structure of quadratic boosting cell (n = 3) is proposed. The proposed structure can produce high magnitude output DC voltage from a low magnitude DC voltage by adjusting the number of quadratic cells in the generalized quadratic cell structure. As compared to cascaded boost converter, the proposed structure sustains lower capacitor voltages at same voltage gain. This feature reduces the capacitor voltage ratings as well as cost of the capacitors utilized in proposed structure as compared to cascaded boost converter. Further on comparison with the existing topologies, the proposed structure generates high voltage gain at a low duty ratio. The voltage gain of the structure can be adjusted as per application by selecting proper duty ratio and number of quadratic cells. The operating principle, the selection procedure of inductors, and capacitors for a boost converter with proposed generalized quadratic cell (n = 3) are presented in detail. The merits and effectiveness of proposed structure are verified by simulation study in MATLAB/SIMULINK platform.
