Hi all,
The following design has serious flaw but it still works which means it's not a proper and professional EE design .
Please tell me ,
1) what's serious mistake in this flawed circuit (which works fine)
2) could you give me suggestion of any kind to check the continuity in the big rectangular box ? you can use chip or other component but the big rectangular box with voltage regulator being the same.
Well, first of all is this regulator used as a welder? Because direct shorts to ground need oodles of juice. Perhaps you should read your textbook on this HW question.
