Hello, i have two questions;

- I gave a 300v sinusoidal voltage to the primary winding of my high frequency transformer but when I checked the graph after simulation it was not a sinusoidal wave, can you please help me find the problem? You can find the equation and the results attache
- Can you please give me the equation for sqaure waveform with 300v magnitude, 50% duty cycle and 20kHz frequency?
