Inductor saturation current
I'm trying to determine an inductor's saturation current, I use a PWM with a gate driver (TLP250) and a 0.4Ω sense resistor at the source which I probe across to capture the current waveform.
I ...

Power MOSFET gets hot while driving Peltier by step-down buck voltage converter
I have a TEC1-12712 Peltier element, which I am driving using Arduino microcontroller through IRFZ44N and buck step down converter (to smooth PWM).
Overall, circuit consists of:
12V, 8.5A max DC ...
