hi Guys
can anybody figure out what does this circuit do ?
i toke it from a tradmill near the dc motor
i want to know where the dc part is in this circuit
i need the schematic form for this circuit
i will attach the picture hope it can help
if u know any circuit that is similar to it
the names of the 6 chips
1-mospec u16c60c
2-kia 7805pi
3-cd 40106be h9605
4-ixys dsei 30-06A
5-st mrc tyn690
6-s21md3v sharp
thanks
An easier way to figure out the circuit is to hold the PCB up to a very bright light while looking at the parts side. Then you can see the copper traces through the PCB and draw out a schematic yourself. No one is going to do it for you. You could also mirror the picture of the foil side in photoshop and place it next to the unmirrored parts side picture, but again, no one is going to do it for you.
The KA 7805 should be the regulator Probably 12vdc. Your AC input by the fuse is then sent to the Diodes near it to be rectified. After that I'm not sure without a schematic.
