I would say this is part of a SMPSU...probably the part AFTER the switching controller and MOSFETs...

So what do you want the rest of us to explain???

Most DVM:s don't particularly like measuring 100kHz square wave, so it'll likely not give very accurate results.
Another, less scientific reason would be that you're using the DC range of your DVM to measure AC (been there, done that

)
