ABSTRACT: A two-input boost converter with voltage multiplier cell is proposed in
this paper. Then a family of two-input converters with and without voltage
multiplier cell are derived and their results are compared to achieve high voltage
gain, low duty cycle, and reduced voltage stress. From the analysis of
different topologies, a modified two-input converter with two-stage voltage
multiplier cell has good operating characteristics. The switch voltage stress
and duty cycle of the modified converter is significantly very less than that
of the other converter topologies. The modified DC-DC converter with 50% duty
cycle achieves a voltage gain of 10 and the results are verified by using
MATLAB/Simulink software.
