This article presents a comparison of the classic .AC circuit analysis method with the method for determining frequency responses employing time analysis (.TRAN) – i.e. Middlebrook’s method. The authors carried out simulations in the LTspice programme. The article also includes the results of a computer simulation of correction circuits in DC/DC buck converters. Moreover, the article examines and compares two methods for determining frequency response of correction circuits. The research is aimed at improving design methods for DC/DC Buck-converters (step-down converters).
