Peltierdevice in simscape no tempdelta

Dear Members,

i want to create a thermalcircuit with an peltierdevice in cooling mode. On the positive port of the device i have connected the current source (+) and on the negative the reference (-). Unfortunately after i insert the parameters to the tec-device and run the circuit, i can't meassure an temperature difference between the Port A and Port B but i can meassure the heatflow and i think thats the right one. I have insert an thermal mass and a conductive condition.

To isolate the problem, i have tried to meassure the temperature difference on the given example (documetation model) from matlab, but with no success.

I would be very grateful for any assistance

Hello Sebastian,

measuring temperature in simscape unfortunately requires an extra step to get it to work. Here is how a temperature sensor can be connected to the shipping example, but there is one more step so please keep reading after the picture:

The PS -> Simulink converter, needs to have it's settings modified to correctly report temperature. Please double on this device and select 'apply afine conversion' to the block. You could also specify the specific units you want the temperature in at this poin.

Regards,

Joel
