Iso-failure probability at 20 years for the 6 modules (complete active rectifier) in
all sea-states (106 considered here) as a function of both the heatsink thermal
resistance and semiconductor current rating
Lifetime cost as a function of energy rating . The economic
optimum with a conventional aging model is marked by a
circle and the optimum obtained with the enhanced model
is marked by a cross.
