Title: Resonant Transformer
Post by: tak22 on June 06, 2011, 03:48:55 PM

What does this recent patent do? It's either a very clever use of obfuscation, or very plain to someone other than me. Please have a look and post your ideas.

I stumbled on it while researching Dan Combine.

Inventors:  Anthony Francis Issa, Jeffrey Messer, John Michael Tobias

Abstract:  Resonant transformer systems and methods of use are described. One aspect may include a primary winding, a secondary winding, and at least one output winding. In further aspects, a transformer may be coupled to the secondary winding. In one aspect, the output winding is coupled to rectifying circuitry, which may be coupled to one or more capacitors.

---------------------------------------------------------------------------------------------------------------------------------------------------

A resonant transformer with an possible OU effect.
To be verified.

With the values as shown in the picture the output optimum resistance  seems to be around 800 Ohms.
The phase angle between input voltage and input current is then around 800.  Resonant frequency 20 -30 kHz.

Concerning the input phase angle: This transformer reacts in the opposite way compared to a "normal" transformer.
With an open output the input phase angle is about zero degrees. Loaded about 80o and goes tovards 90o with the output shorted.

The sizes ratio of the ferrite rods and their and the coils' mutual positions affects both the output voltage and the efficiency of the "transformer".

This is the one of the good results;
Input: 3.53 V , 2.7 mA ,  81.2 degr.        Output: 1.17 V     819 Ohm       n=  114.6%
(Measured with swapped probes; A, B <--> B, A and its phase average value used for improved calculation)

Measurements  Input: V x I x cos angle  Output:  U2/R    n=Output/Input (watts)

Please check Input vs Output V??

Hello kampen,
With the numbers shown, the calculations are correct.

What is the problem?
