POWER COMBINING TRANSFORMER BASED ON AUTOTRANSFORMER AND TWO WINDING TRANSFORMER

摘要

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.
