Tepe akım modu kontrollü Zeta dönüştürücünün küçük işaret analizi

Abstract

In this study, small signal analysis of peak current-mode controlled, non-isolated Zeta converter is presented. The PWM-switch model in Continuous Conduction Mode (CCM) is utilized in the analysis. The control to output voltage transfer function is derived in symbolic form including the esr of the output capacitor. The exact zeros of the transfer function are given in symbolic form. However, the peak current-mode PWM-switch model yields 5th order polynomial in its denominator, which necessitates approximate root analysis in finding the symbolic equations of its poles and quality factors. By using this analysis, the approximate poles and quality factors also derived symbolically in the paper.
