Appendix D DC Common Bus Applications
Common Bus Capacitance
Example
In this example, the sum of the leader IAM power rail modules capacitance
(6530 μF) and the follower IAM power rail modules capacitance (5280 μF)
equals 11,810 μF total bus capacitance.
The sum of the follower IAM module power rail equals 5280 μF additional bus
capacitance.
