6. Conclusion
In this paper, the modified DC/DC high step up converter has been
proposed. In this paper, the modified topology for high step up
application has been proposed that reduced input current ripple.
Switching scheme and operation modes of the proposed converter have been
investigated. Output voltage gain and input current ripple of the
proposed converter have been calculated in steady state operation mode.
The proposed converter has been compared with the recently presented
DC/DC high step up converter. The comparison result revealed that the
input current ripple in the proposed converter reduced much more than
other. In the proposed converter, hard switching is done that cause to
reduce the efficiency of the converter. The proposed converter has been
simulated in PSCAD/EMTDC to evaluate the operation of the proposed
converter. The simulation results have been verified the performance of
the proposed converter and its mathematical analysing.
