Power supply 0-30V 0-10A

[jopapadogr]

Hi all,

After i searched all the forum for power supply schematics and no founding them (dead links), i decided to send this post.
I'm looking for a power supply bench able to give 0-30V 0-10A output with current limmiting capability

Thanking in advance

what is the input voltage range??

 

[jopapadogr]

I have a 220V / 30V 10A + 15V/0,2A AC transformer

Try using the OPA55X range from Texas Instruments, they have ICs with very simple voltage and current regulation implementations.

Most practical way is to change the AC voltage into DC (Full wave rectifier with or wmithout stepping down), then design a buck converter to take the votlage down to 30V. It is a common power electronics circuit. You have to choose FET switches/heatsink to handle so much of current. Current limiting should not be a big deal if you will be able to realize this circuit. Open any power electronic text book for circuit reference.
