Improving power supply in a converter?

[canidoit]

What exactly do you do when improving power supply to improve a converter?

What is usually replaced in a power supply?

How are the upgrades done, is it replacing caps using a different brand, increasing it's value for something, using larger wattage resistors?

the ones i've seen,  new transformer (usually toroid-mounted to side of chassis), regulators, and bigger caps.

& i see radial cans standing on the pads of removed SMD caps.
LOTS of 'em.    all over the place.

Is there like a usual process when upgrading caps?

Like use a particular brand or change of value or use a different type of cap?

Consider that in general, the power supply is nothing more than the mains transformer, a rectifier (or two), regulators and filter caps, then there's not much to it.

If it's a switcher, or uses one, then don't even bother.

Some people like to replace caps with "Better," where "better" has different definitions.

And you won't find many resistors in the supply; generally, all that you'll see are the feedback divider resistors and those don't need to be "high power" as long as the current through them is low enough so that the power dissipated in them doesn't exceed ratings. (This is simple math.)

Without knowing the converter you wish to "upgrade," and the quality of its existing power supply, it's impossible to speculate about any improvements.
