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.*

Abstract
Bu
çalışmada, tepe akım-modu kontrollü, izole edilmemiş Zeta dönüştürücünün küçük
işaret analizi sunulmuştur. Yapılan analizde PWM anahtarlama modeli Sürekli
İletim Modu’nda (SİM) değerlendirilmiştir. Kontrol işaretinden çıkış
gerilimine olan transfer fonksiyonu çıkış kondansatöründeki esr (eşdeğer seri
direnç) de dâhil olmak üzere sembolik formda elde edilmiştir. Transfer
fonksiyonuna ait sıfırların kesin çözümleri sembolik olarak verilmiştir.
Ancak, elde edilen tepe akım modu kontrollü PWM anahtarlama modelinin paydası
5. mertebeden bir polinom olduğundan, kutupların ve kalite faktörlerinin
sembolik formda bulunması için yaklaşık kök analizi kullanılması
gerekmektedir. Bu analiz kullanılarak yaklaşık kutuplar ve kalite faktörleri
de sembolik formda türetilmiştir.
