Zusammenfassung:The present invention relates to a power combining transformer based on a single winding transformer and a double winding transformer which operates only one general transformer or a single winding transformer in a low power mode, and operates all of the single winding transformer and a double winding transformer at the same time in a high power mode. The power combining transformer comprises: the single winding transformer operating in the low power mode by determining an output characteristic by a first input impedance (Zin1); the double winding transformer operating with the single winding transformer at the same time with an input by determining an output characteristic by a second input impedance (Zin2); a first-side winding and a second-side first winding configuring the double winding transformer; and a second-side second winding configuring the single winding transformer. 본 발명은 저 전력 모드에서는 일반적인 변압기나 단권변압기 하나만 동작하며, 고 전력 모드에서는 단권변압기와 2권선 변압기 모두 동시에 입력으로 동작하도록 한 단권변압기와 2권선 변압기 기반 전력 결합 변압기에 관한 것으로, 제 1 입력 임피던스(Zin1)에 의해 출력 특성이 결정되어 저전력 모드에서 동작하는 단권 변압기;제 2 입력 임피던스(Zin2)에 의해 출력 특성이 결정되어 고전력 모드에서 단권 변압기와 동시에 입력으로 동작하는 2권선 변압기;상기 2권선 변압기를 구성하는 1차측 권선 및 2차측 제 1 권선; 및 상기 단권 변압기를 구성하는 2차측 제 2 권선;을 포함하는 것이다.
