I have seen many high wattage (like 1200 or 1500 W) boost converters but no buck converters with that high a wattage or power rating.
I'm planning to make a buck converter (input: 35 V, output: 3 to 35 V, current: 30 A max and adjustable).
Are there any restrictions on the power of a buck converter, or are there any certain limitations on the current it can output?
I don't want to buy a discrete buck converter IC; I intend to use typical PWM chips like uc38xx, tl494, etc. or even opamps.
