hi guys,
i have problem with my output at secondary of high frequency transformer. It just show a spike only. I need a rectangular wave. Currently i'm using 20kHz frequency. Anybody can help to explain what happen in this cct. Thank you.

is it i need to increase the inductance?
 

What is frequency of signal? Transformer can't "transfer" constant level signals; as you know it use variation of applied voltage (variation of magnetic flux respectively) to proper work and transfer energy in secondary winding(s). Maybe for higher frequency applied signal you'll see a more close square wave signal in secondary, but never exactly same wave like applied signal.
 

Output will only show a positive pattern of a half sinus wave, one line of the otput should be grounded also.
