[ 1 ] - طراحی و کنترل ساختارهای جدید پایش‌گر یکپارچه کیفیت توان بین خطی بر اساس مبدل‌های چندپورته AC/AC
مبدل‌های کاهش‌کلیدیافته با توجه به مزایای متعدد از جمله هزینه و وزن کم، اندازه کوچک مورد توجه قرار گرفته‌اند. تاکنون ساختارهای مختلفی در جهت کاهش تعداد کلیدهای مبدل‌های قدرت در مقالات ارائه‌شده که می‌توان آن‌ها را به دو دسته اینورترهای تک‌خروجی و اینورترهای چندخروجی دسته‌بندی کرد. در این مقاله سه ساختار مبتنی بر مبدل‌های کاهش‌کلیدیافته بر اساس مبدل‌های 15 کلیدی 3 ساق و 15 کلیدی 5 ساق و 12 کلیدی...
[ 2 ] - Analysis of Switched Inductor Three-level DC/DC Converter
A non-isolated DC/DC converter with high transfer gain is proposed in this paper. The presented converter consists of the switched inductor and three-level converters. The DC/DC power converter is three-level boost converter to convert the output voltage of the DC source into two voltage sources. The main advantages of DC/DC converter are using low voltage semiconductors and high gain voltage. ...
[ 3 ] - A Generalized Modular Multilevel Current Source Inverter
This paper proposes a novel topology of multilevel current source inverter which is suitable to apply in low/medium voltage. The proposed topology is capable of producing desirable bidirectional output current levels. Furthermore, it can employ symmetrical DC current sources as well as asymmetrical ones which is a significant advantage. Asymmetrical mode makes it possible to generate a great nu...
[ 4 ] - A New Robust Control Design Based on Feedback Compensator for Sssc
In this paper, the modified linearized Phillips-Heffron model is utilized to theoretically analyze asingle-machine infinite-bus (SMIB) installed with SSSC. Then, the results of this analysis are used forassessing the potential of an SSSC supplementary controller to improve the dynamic stability of apower system. This is carried out by measuring the electromechanical controllability through sing...
