A Modified Quadratic Boost Based P-Type Structure with Inverting Output

Abstract

In This paper a modified quadratic boost converter (MQBC) based p-type structure with inverting output is presented. The proposed converter evolution based on integration of p-type converter structure and modified quadratic boost configuration. Output side inductor constitutes continuous output current. Main features of proposed MQBC converter are high voltage gain, continuous input current, inverting output which is used for LED driving, data transmission etc. In addition to that proposed converter has buck capability at duty ratio D≥0.2929. The detail description of proposed MQBC converter, steady state analysis, modes of operation, voltage and current stress analysis of semiconductor elements are presented in this paper. Further a 40/400 V, 300 W converter is validated with simulation results.
