Hi guy today We make 220V to 24V 15A Power Supply | Switching Power Supply | IR2153 from ATX power supply.

Step 1: Choise the PSU

I use OLD COMPUTER PSU about 300w from china. I cut all the wire not necessary

Step 2: Take the Necessary Component

The first i use iron solder for take 2 big heatsink. We only use the heatsink, all transistor and mosfet we don't use after that, I take 2 capacitor 330uF/200v, capacitor 105

Step 3: The Transformer and Inductor

We have the transformer, inductor 2 big capacitor 330uF/200v,2 heatsink,2 resistor 330K , 1 fuse 5A/250V, 1 NTC MF725D9. The tranformer don't have the CT pin. The inductor have 6 pin. 2 pin of small wire we don't use.

Step 4: Buy More Component

We need to buy some component.

2 capacitor 1uF/275v.

1 Line Filter Transformer.

1 Bridge diode KBL610.

1 Capacitor 220uF/16V

1 Capacitor 1uF/50V

1 Diode UF4007

1 Resistor 47K/5W

1 Resistor 10K

2 Resistor 22 ohm

1 capacitor 1n (102)

2 Mosfet irf730 ( irf740,irf840..)

1 Double diode 20100CT

1 Capacitor 100n (104)

1 resistor 10K

1 led 5mm

1 capacitor 1000uF/50V

1 socket 8 pin

1 IC IR2153

For more detail: Please copy the name of component and paste to google image search

Step 5: The Schematic and PCB

The Schematic i design by Eagle Software and make PCB use Sprintlayout software. I hava attach the PDF file for you make it by yourself at home. If you want the good PCB you can upload gerber file to JLCPCB.COM, i alway make PCB online from JLCPCB.COM They cheap and good quality. You can download all of them below Gerber file, Schematic and PCB at PDF file

Step 6: Solder the Component, Some Thing About 750W 24V DC Motor Speed Controler

At the top of PCB we have the name of component, you just put exacly component and solder. 750W 24V DC motor speed controler i have show you in previous project, you can check again for more detail
