Order diminution of cuk converter using factor division algorithm and routh approximation method.

Cuk converter is a fourth order, non-linear DC-DC converter. It is a combination of both buck and boost converters with inverting topology where the output may be higher or lower with regard to the input. This paper presents diminution of Cuk converter using two different techniques, namely factor division algorithm to obtain numerator coefficients and Routh approximation method to obtain denominator coefficients which simplify the model to reduce simulation time and cost as compared to original system. For the original system and its reduced order systems, the outcomes are assessed using step and Bode responses. Additionally, to analyze the effectiveness of the developed model, the integral absolute error and the integral of the time-weighted absolute error are calculated. [ABSTRACT FROM AUTHOR]
