Hi Ole, I have already connected a 400w spotlight and a 116w bulb. Is not it possible to directly discharge the primary winding like a boost or buck converter to lower the impedance? Greetings Sven

Hi Sven,

Then a variable electrical load is still needed at the generator end. Perhaps it is just as easy to find an electrical load matching the output transformer directly without first putting it through the motor and generator.

Regards
Ole

Hi Ole, I can connect the Dc engine with a generator that acts like a brake at last. I still have a Ferroresonanzrafo if you can test it as a load, but I think that will be the same problem. maybe we do not even know how we have to deal with this energy. Regards Sven

Hi Sven,

The boost and buck converters change the transformation ratio by changing the duty cycle or ratio between input and output part of the cycle. When using thyristors this gives the problem of shutting them off while current are going through them. Shut off has to be done externally by bypassing the current through them. Transistors are usually used instead of thyristors as well as much higher switching frequencies for being able to use smaller transformers for the same power.

Ole

Hi Sven,

The impedance is reduced by mechanically loading the motor or if it is a transformer the secondary is loaded which cancels some of the field in the primary coil.

   Hi Ole,
 
 Here is my video what I did back then. At high load, the lamp also went out and at idle it shone brightly. So you could extract some of the energy from the primary coil to reduce the impedance. Or am I wrong.
 
 regards

 Hi Ole,
 
 I had rather thought of a snubber, about a freewheeling diode, I could unload the primary coil immediately partly.
 
 I tried that with a DC motor and a self-built IGBT push pull inverter. At idle, the coils were disposed of energy via the freewheeling diodes and the capacitor in series and a light bulb. The lighter the secondary, or the lighter the DC motor was, the brighter the bulb was. Under load, the impedance dropped and the energy thrown back, I make a drawing or cut.
 
 regards
