Hi guys, I'm pretty new to all of this so bare with me...
I have been working on making an electromagnetic levitator and the pwm for the electromagnet is controlled with a tl494. Speaking with someone who has built one told me that I need to set the frequency to 200khz. The only problem is that I don't know how to calculate the resistor and capacitor values needed. I have found the equation used in the datasheet, but I cannot figure out how to calculate what I need by using it. Can anyone help me?
Thank you for any help!
