“…The author controlled both the AC and DC sides of the inverter. The sliding mode control (SMC), which is preferred to regulate the capacitor voltage on the DC side, enabled the system to respond quickly and dynamically in case of change in the input voltage and output load [40]- [42]. By comparing the Proportional Integral (PI) Control and the SMC Control, it was determined that the dynamic response of the PI control was slower.…”

One of the disadvantages of the charging systems and voltage regulation systems in alternative energy systems is that when the direct current (DC)/alternative current (AC) or AC/DC conversion is made from the energy source, the energy flow at 2ω frequency between the direct current side and the alternative current side causes ripples in the DC, inductors, and capacitors. The ripples that occur in 2ω frequency increase the harmonic distortion and reduce the efficiency in the photovoltaic energy system. For addressing this problem, different control methods are evaluated in this paper for the elimination of ripples that occur at 2ω frequency, both on the perspective of DC control side and AC control side with a thorough comparative analysis with existing results in the literature. In the present study, the model of Single-Phase Quasi-Z Source (QZS) inverter and closed-loop control methods of the inverter are examined and compared with pulse width modulation (PWM) methods. In addition, the control methods are used to eliminate the ripples at 2ω frequency in the use of inverters, and the advantages and disadvantages of these methods are presented. INDEX TERMS QZS inverter, suppression of 2ω ripple, control methods, pulse width modulation. I. INTRODUCTION

“…Eviricilerin kontrolünde hedefler çalışma yerine bağlı olarak değişkenlik göstermektedir. Şebekeye bağlı bir eviricide akım kontrolü sağlanırken [13], [14], bağımsız çalışan bir eviricide yük geriliminin kontrol edilmesi temel hedeftir [15], [16]. Kontrol işlemleri topolojinin etkinliği üzerinde önemli bir rol oynadığından birçok farklı yöntem ile eviricilerin kontrolü sağlanmıştır.…”

“…Ancak bu durum kontrol yapısını karmaşıklaştırmakta ve yüksek performanslı mikrodenetleyici ihtiyacı doğurmaktadır. Kayan kipli kontrolde ise çatırtı sorunu olarak tanımlanan olumsuz etki üzerine birçok çalışma yapılmıştır [16]. Özellikle yüksek dereceli sistemlerde yaygın kullanılan üstün burulma algoritması (ÜBA), kontrolün doğruluğunu artırırken çatırtı etkisini azaltmaktadır [21].…”

This paper presents a Super Twisting Algorithm (STA) based Sliding Mode Control (SMC) method for 9-Level Packed E-Cell (PEC) inverters. Firstly, the mathematical background of the PEC inverter is presented. Then, an objective function was defined for the regulation of inverter output voltage. SMC method is designed using the objective function. Finally, STA and SMC methods are integrated to eliminate the chattering effect. The effectiveness of the control algorithm was investigated by simulation studies.
