Abstract

Nowadays, direct current (DC) voltage is required for the operation of the machines used in many industrial applications. DC voltage generating photovoltaic (PV) panels or other DC voltage generators need to be converted from the voltage level produced by the DC voltage levels required for the operation of the machines. The conversion of a DC voltage to a different DC voltage is performed by DC-DC converters. The most commonly used DC-DC converters in the literature are buck, boost, buck-boost, CUK and SEPIC converter. In this study, different control methods are used in order to reach the desired voltage level of the output voltage of the equivalent series resistance and ideal SEPIC converter in continuous current mode. Conventional Proportional-Integral (PI) and Sliding Mode Control (SMC) methods are used to ensure that the converter reaches the desired voltage level. PI controller parameter values are calculated according to trial and error method. In order to compare the performances of the controller used in the case ideal and equivalent series resistance cases, the controller parameters are taken the same. SMC is shown to perform better in ideal and equivalent series resistance SEPIC converter compared to the traditional PI controller from simulation results. Besides, modeling and controller applications of SEPIC converter are realized by using MATLAB / SIMULINK program.

SEPIC Dönüştürücünün Sürekli Akım Modunda Kayan Kipli Kontrolü

Abstract

Günümüzde birçok endüstriyel uygulamalarda kullanılan makinaların çalışması için doğru akım (DC) gerilime ihtiyaç duyulmaktadır. DC gerilim üreten fotovoltaik (PV) paneller ya da diğer DC gerilim üreteçlerinin ürettikleri gerilim seviyesinden makinaların çalışması için gerekli farklı DC gerilim seviyelerine dönüştürülmeleri gerekmektedir. Bir DC gerilimi farklı bir DC gerilime dönüştürülmesi işlemi DC-DC dönüştürücüler tarafından gerçekleştirilmektedir. Literatürde en sık kullanılan DC-DC dönüştürücüler; alçaltıcı, yükseltici, alçaltıcı-yükseltici, CUK ve SEPIC dönüştürücüdür. Bu çalışmada sürekli akım modunda eşdeğer seri dirençli ve eşdeğer seri dirençsiz SEPIC dönüştürücünün çıkış geriliminin arzu edilen gerilim seviyesine ulaşması için farklı kontrol yöntemleri kullanılmıştır. Dönüştürücünün arzu edilen gerilim seviyesine ulaşmasını sağlamak için geleneksel Oransal-İntegral (PI) ve Kayan Kipli Kontrolcü (KKK) kullanılmıştır. PI kontrolcü parametre değerleri deneme-yanılma yöntemine göre hesaplanmıştır. İç dirençli ve iç dirençsiz durumda kullanılan kontrolcü performanslarını kıyaslamak amacıyla kontrolcü parametreleri aynı alınmıştır. Elde edilen simülasyon sonuçlarından kullanılan kontrolcüler kararlı durum hatası, yerleşme zamanı ve yükselme zamanı gibi başarım parametreleri açısından kıyaslanmıştır. KKK hem dirençli hem de iç dirençsiz SEPIC dönüştürücüde geleneksel PI denetleyiciye oranla daha iyi sonuç verdiği görülmüştür. Simülasyon çalışmaları MATLAB/SIMULINK programı kullanılarak yapılmıştır.
