I am trying to design a circuit for 5 Thermal Electric Control(TEC) I am given 2 power sources 1) 0-60V; 0-12A 2) 0-12.5V; 0-60A The thermostat requires a voltage of 12V to operate and is able to deliver an output of 12V and 10A.
simulate this circuit – Schematic created using CircuitLab
Each TEC requires a voltage of 12V and a current of 4A to operate. If I connect the modules in parallel I will meet the voltage requirements but not the current requirements. and if I do it in series it will be the opposite. I thought about using transistors, to amplify the current for the parallel connections, but I don't think it will work in a real-life situation. Can anyone help me with this problem? any help will be greatly appreciated! :)
