I have to design an SMPS circuit that uses a MOSFET and an Arduino to switch it on and off (PWM)
the input to the circuit must be 230v AC and the output must be 47v DC
I came across a lot of buck circuits but they all have a very low input and output voltages (12-10v) is there any way to step down the 230v ac supply before implementing the buck converter or can it be implemented directly
I know I sound stupid but I haven't worked with such high voltages before any help would be appreciated

 

Can you use a transformer to reduce the 230V AC voltage?

 

Can you use a transformer to reduce the 230V AC voltage?

I can but haven't seen any transformer higher than 24v neither have I made one

 

How much current @ 47V DC?

 

How much current @ 47V DC?

500ma max
I don't have to use it anywhere it's for my power electronics subject at college (self study type)
