Why is it that current goes up dramatically if i put a flyback diode anti-parallel to the coil in this circuit?
Same is when i put a diode parallel to the transformer, the current isn't frequency dependant anymore, without diode: 30V / 0,3A. with diode: 3V / 1A (1A limit from power supply). i don't get it.
anyway, problem solved. without the diode current draw is small.
