Design and component analysis of high gain quadratic boost converters with fault diagnosis and remedial measure

Abstract EN

This paper attempts to design a high voltage gain quadratic boost dc-dc converters.

Four different design topologies were considered by their high voltage gain cells which were studied and analyzed through performance and component analysis.

Component analysis is performed for the four topologies of high gain quadratic boost DC-DC converters by surveying and examining different elements used in the four topologies to obtain the best suitable option as per the size and cost.

Henceforth, performance analysis is performed to find power loss across each element used in all four circuits.

Further, from the results of performance and component analysis of the design topologies of high gain quadratic boost DC-DC converters; the lightweight and cheap topology for high gain DC-DC conversion are selected.

Moreover, the mode of operation of the superior topology obtained from the comparative study on the family of high gain topologies is studied and analyzed.

Subsequently, the selected circuit is also explored through simulation analysis for which the operation and waveforms are obtained.

This work also focused on identifying the type of switch fault and worked on the remedial measures to rectify the switch fault to ensure the smooth working of the converter whenever the fault occurs.

Finally, a 40 W prototype is built to validate the results obtained from the analytical and simulation study which is carried out in MATLAB/Simulink.
