Wait, I just thought of the inrush current. 63kA? That can't be right... I know the input cap is for smoothing but 47,000uF seems like a lot. Following this]https://www.electro-tech-online.com/threads/how-to-calculate-the-value-of-a-smoothing-capacitor.106374/]this] formula I get about 56,000uF assuming 14A with a 2v drop. That's a lot of capacitance. Would I be able to reduce the capacitance to say 5,600uF instead? Using an NTC thermistor with a resistance of 2.5 \$\Omega\$ @ 25C would limit the inrush to 10A roughly which is fine, but having say a 30mOhm resistance at full load reduces the max current I can draw at 24V to 10.5A. I can get around this buy suppling the LM723 with 28V instead of 27V. Am I over thinking this too much? |
