Abstract

Bu buluş genel anlamda tüketici elektroniği ürün alanı, özellikle de, televizyon ve ses teknolojileri alanında kullanılan pozitif ve negatif güç devrelerinde meydana gelebilecek anormalliklere karşı koruyucu cihazlarla ilgilidir. Bir uygulamada, çiftli güç kaynağının son kademe çıkış portu yükünde (RL) sen akım negatif geribildirim rezistansı (RS71) eklenir ya da algılama kaynağı olarak kullanılır ve Rezistans (R46V) ve Kapasitorun (C46V) entegrasyonu sayesinde ve basınca karşı duyarlı anahtarlama birimi (VD46) ya da Diyot (D46) devre parçası vasıtasıyla, normalde kapalı olan ve aşırı yük iletim özellikli aşırı yük kapatma cihazlarına bağlanır ve böylece pozitif ve negatif güç kaynağında meydana gelebilecek OCL devresi aşırı akım ya da diğer anormalliklere karşı zamanında ve etkili koruma sağlanır.
