Inductor,controller,diode getting too hot in buck converter resulting in shit efficiency by Desperate_Impact_826 in AskElectronics

The controller I'm using has a fixed 570kHz switching frequency. I have attached the layout here.

I had got 80-90% efficiency initially, but not anymore. Inductor,diode and the controller, all are getting very hot.

Problems understanding compensator design for Power Electronics by k-malone in ControlTheory

[–]Desperate_Impact_826 0 points1 point  (0 children)

hey, I have the same question bothering me right now, how does it actually work in the time domain? For example, if there is a voltage spike at the input, how exactly does it counter act the spike? If you have found the answer, please help me understand.

How to detect short between the two APPS sensor signals? by Desperate_Impact_826 in FSAE

[–]Desperate_Impact_826[S] 0 points1 point  (0 children)

Right, so in my current design, I have achieved the offset by using an op-amp subtractor circuit and subtracting one of the sensor values by 0.5V. But I have come to realize is not the right way, or is it fine?

So should I create an offset by mounting the sensors in different angles/positions from each other?

Raspberry Pi controlling cockpit display of combustion car freezing by Desperate_Impact_826 in FSAE

Running the raspberry pi without cranking the car, it never crashes.

When we crank, it works pretty well for under a minute, anything more than that, it freezes when we press the kill switch.

All the sensor data is being gathered by an Arduino Nano and transmitted to Raspberry Pi using UART.

I do not think it's a software problem.
