Abstract

This paper presents design and control of dual-switch non-inverting buck-boost converter CBB . This converter is designed to simplify the compatibility of electronic ballast with simple and low cost LED drivers. The converter provides starting voltage and current limitation of electronic ballasts, which operates at continuous conduction mode C.C.M. . The voltage of load terminal is controlled by adjusting the duty cycle of the PWM regulator. Although both converter switches are controlled separately, one feedback control loop is needed to obtain the desired compensator level. Appropriate control requirements have been defined by analyzing open-loop characteristic of converter transfer function through the small-signal model of CBB, which lets decide about the control strategy and analyse the stability and performance of the closed loop control system. In order to obtain the desired output voltage, Type-III rational controller is preferred because of the non-minimum phase feature in the converter boost mode. The performance of the synthesized voltage controller is verified by comparing of the pre-determined performance requirements and the obtained simulation results.

Özet

Bu çalışmada iki anahtarlı evirmeyen alçaltıcı-yükseltici dönüştürücü tasarımı ve kontrolü sunulmaktadır. Sürekli iletim modunda çalışan dönüştürücü, balastların temel işlevi olan ateşleme voltajını ve akım sınırlamasını sağlamaktadır. Bu dönüştürücü basit ve düşük maliyetli LED sürücüleri ile elektronik balastların uyumunu basitleştirmek için tasarlanmıştır. Dönüştürücünün anahtarları ayrı ayrı kontrol edilmesine rağmen istenen kompansatör seviyesini elde etmek için bir geri besleme kontrol döngüsü kullanılmıştır. Uygun kontrol gereksinimleri dönüştürücünün küçük sinyal modeli ve sistemin transfer fonksiyonunun açık döngü karakteristiği analiz edilerek tasarlanmıştır. Arzulanan çıkış gerilimini elde etmek için Tip-III rasyonel kompanzatör tercih edilir. Çünkü dönüştürücü yükseltme modunda minimum fazlı olmayan bir sistemdir. Kontrolcünün performansı, gerçek zamanlı performans gereksinimleri ve elde edilen simülasyon sonuçları karşılaştırılarak doğrulanmıştır
