/diy/ - Do It Yourself

I'm doing an inverter as a part of a project, using IGBTs in a h-bridge configuration. Naturally when it comes to this kind of topology the switching does have some overshoot plus ringing tied to it, and it does show on the load albeit at reasonable levels (say half a volt switching noise on a couple dozen volts of output voltage). The issue that I'm having is that I'm using a voltage divider to monitor the output, and while it does attenuate the output waveform properly, for some reason the switching noise just passes through directly (in fact it seems to be carried to every goddamn part of the circuit after the h-bridge unchanged). Does anyone has any idea of what could be causing that? (and no, it is not the probes picking up EMI).
I understand that I could try adding some snubbers to try and mitigate/get rid of the ringing altogether but what I really want to know is how can the noise just go through like that.
