# DC-link capacitor sizing
# Scope: Capacitor discharge during supplied power interruption; constant power.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

power = 100 W
duration = 10 ms
highVoltage = 48 V
lowVoltage = 40 V

capacitance := 2*power*duration/(highVoltage^2-lowVoltage^2) [uF]

check capacitance budget: capacitance <= 4000 uF

scenario alternative: power = 80 W
