Abstract

Elektrikli araçtan (EA) şebekeye enerji aktaran uygulamalarda araç üzerinde yer alan doğru akım (da)/da yükseltici dönüştürücü devrelerinin hafif, düşük hacimli ve yüksek verime sahip olması gerekmektedir. Bu avantajı saplamak için izolesiz da/da dönüştürücü devrelerinde kullanılan bobin boyutlarının düşürülmesi gerekmektedir. da/da yükseltici dönüştürücü devrelerinde senkron ve serpiştirilmiş senkron topoloji yapıları kullanılmaktadır. Bu çalışmada, deneysel olarak bu iki da/da yükseltici devresinin, batarya gurubu ve kablosuz EA şarj yapısı bulunan bir sistemdeki performans analizleri gerçekleştirilmiştir. Çalışmada aynı güç değerlerinde serpiştirilmiş senkron da/da yükseltici topolojisinde bobin akımlarının ve çıkış gerilim/akım dalgalanmalarının azaldığı, verimin artış gösterdiği sunulmuştur. Farklı çalışma şartlarında iki devre topolojisinin performans karakteristikleri deneysel olarak kanıtlanmıştır. EA araçlarda yüksek şarj/deşarj uygulamalarında serpiştirilmiş senkron da/da yükseltici dönüştürücü topolojisinin kullanılmasının avantajlı olduğu gösterilmiştir.

dc/dc Boost Converter Topologies and Experimental Comparison in Electric Vehicle to Grid Applications

Abstract

In applications that transfer energy from the electric vehicle (EV) to the grid, the direct current (dc)/dc boost converter circuits on the vehicle must be light, low volume, and high efficiency. To achieve this advantage, the inductor sizes used in non-isolated dc/dc converter circuits must be reduced. Synchronous and interleaved synchronous topology structures are used in dc/dc boost converter circuits. This study conducted experimental performance analyses of these two dc/dc boost circuits in a system with a battery group and a wireless EV charging structure. The study presents that in the interleaved synchronous dc/dc boost topology at the same power values, inductor currents and output voltage/current ripple decrease, and efficiency increases. The performance characteristics of the two circuit topologies under different operating conditions have been experimentally proven. It has been shown that using interleaved synchronous dc/dc boost converter topology is advantageous in EVs' high charge/discharge applications.
