I intend to use this circuit from Texas instruments tl494 datasheet to build 50a,15v power supply. My input voltage is 24dc from a step down ordinary transformer.
From this circuit, that av screenshot with my phone ,the output current is 10a and is controlled with the current sensing resistor R13 which is 0.1 ohms ; meaning it's dissipating 10w, at 1V. This one implies that my 50a will dissipate 50w, at 1v.
Now my question is;
Can I reduce this error amplifier's sensing voltage to 0.5v so that I can save 25w of dissipating power ; or will it affects the normal operation of tl494?
