Boost Converter with Generalized Quadratic Boosting Cell with Reduced Capacitor Voltage Stresses

摘要

A complete simulation of the proposed converter with generalized structure of quadratic boosting cell (n = 3) is performed in MATLAB/SIMULINK. The proposed converter shows an increase in its output voltage gain even at a low duty ratio justifying the dependency of output voltage gain on number of quadratic boosting cells. Also reduction in voltage stresses is mainly observed across the capacitors when the proposed converter is compared with the cascaded boost converter for same duty ratio (d = 0.5). This feature reduces the capacitor voltage ratings well as cost of the capacitors utilized in proposed converter. The hardware implementation of the proposed converter needed to be accomplished in the near future to verify its merits and effectiveness.
