Hello,
I have built a circuit for controlling an electromagnet in an active magnetic bearing. I'm able to feel the force of the EM, but I'm a bit confused on why the high side amplitude to the gate is only 7V, when the low side is 15V. I'm testing with 0V or 30V on the power side and 15V on the logic side at the moment. But I get the same result with only 7V out from HO to the gate of the high side transistor.
It could be a broken component as I have already released the magic smoke one time. Or a bad component choice, or the 30V supply, but I don't see a difference between 0 and 30V on the power side. Or it might be that it supposed to be like this. I'm confused if it's supposed to be like this or if it's something broken.
