Debunking Transformer Performance Myths
In the October 2009 Issue of the How2power Today Newsletter an article involving measurements with the Bode 100 has been published. In their article "Debunking Transformer Performance Myths" the authors Steven M. Sandler and Danny Chow of AEi Systems, Los Angeles, California intend to dispel three common myths regarding transformers, and more generally, magnetic coupling.
- Myth 1: The turns ratio of a transformer is the
and 
is the reciprocal of 
- Myth 2: The leakage inductance of a transformer is based on the coupling from one winding to another
- Myth 3: The inductance of a transformer is
To provide the proof that these myths are false, three transformers were constructed. Each transformer included only two windings, with 15 turns on each winding. A series of measurements were made for each of the three transformers. All of the measurements were made using one piece of test equipment, OMICRON Lab’s Bode 100 portable vector network analyzer.
