Lifetime of electrolytic capacitors does indeed drop with heat and in a VSCF the waste heat is generated directly in the electronics vulnerable to it. Additionally the issues are worst in mid-flight and increase if load increases due to alternate failing, so you have a real possibility of losing power mid-ocean. By contrast IDG generates waste heat in systems insensitive to it, probably fails when engine speeds change which tends to be near safe landing and does not particularly care what the load is. | |
