Abstract

Güç kipleme sistemleri ve yöntemleri veri simgelerinden bir genlik dalga biçimi ve faz dalga biçimi üretir. Genlik dalga biçimi bir alçak frekans kismi ve bir yüksek frekans kismi içerir. Faz dalga biçimi faz kiplemesine tabi tutularak faz kiplemeli bir dalga biçimi üretilir. Güç yükselteci güç kaynagi girisi ve güç çikisi içerir. Faz kiplemeli dalga biçimi sinyal girisine uygulanir. Genlik dalga biçiminin alçak frekans kismi yüksek verimlilikte yükseltilerek yükseltilmis alçak frekans kismi üretilir. Yüksek frekans kismi düsük verimlilikte yükseltilerek yükselmis yüksek frekans kismi üretilir. Yükseltilmis alçak ve yüksek frekans kismi birlestirilerek birlesik yükseltilmis genlik dalga biçimi üretilir.
