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
 
 Sven

 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

   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.
 
 Regards
 Ole

   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
