I am presently rebuilding a DC load bank that I designed and built a number of years ago. At present it is used to test DC powersupplys and discharge rechargeable batterys with a constant current. The attached schematic is the current design. What I got to thinking about was to put a pelter junction in series with the darlington transistor that is used as a constant current load. For extended periods the heatsink gets quite warm. My thoughts are with a pelter junction set for cooling it would offset some of the heat caused by the existing transistor.
Your thoughts please
