Hi guys, I´m new to Switching Power Supplies. I was reading the EPR32.pdf and I find a device to assembly. This project has an output of -24v/50mA. How I can swap the voltage to positive and improve the current Iout to 1A?

 

Hi,

Basically you need to rewind the transformer with inverted polarity of the 24V output (mind the dot).
Thicker wires, maybe even bigger size core. Bigger catch diode and bigger capacitor....
A lot of modifications ... is it worth it?

The polarity of that output relative to the other outputs is defined by the transformer windings, so you'd need to replace the transformer. At that point you're basically looking at an entirely new design. You're also asking to double the total output power of the supply...
 

Hi,
Kindly post exactly what is your required voltage and current ratings.
