Hi Spikee, For the best sharing of the currents give eacht Fet a small Source resistor (0.1 Ohm) And, don't forget to place the Fets on the good site of the heatsink! This is the way to do it... Kind regarts, Blackdog |
| Spikee:
Can i use the wires as source resistor ? i can 4-wire measure it to be exact. |
| robrenz:
Copper has a large resistance variation with temperature change so it would not be as good as a low temperature coefficient resistor |
| Spikee:
i have one laying around but another ... guess i will have to order another one from farnell. |
| blackdog:
Hi Spikee, 0.1 Ohm wire resistor... Mmmm ~ 9cm, copper wire, 0.1mm diameter. Try it, Kind regarts Blackdog |
