Why not a peltier cooler? One of my constraints is that I don't want to generate any more heat.
I don't have access to the measuring device, so I really do need to sink actual current.
I would like some ideas/suggestions on how to shunt current in a PWM circuit. The load on the circuit is not sufficient to shunt the amount of current necessary.
I need to shunt about 1.0 additional amps during the "on" cycle of the pulse. The duty cycle could be 40 - 60% and the frequency is...
