This paper presents an approach to power electronic converter design in
which the objective is to minimize the life cycle cost when the
converter is used to supply a residential customer. In the paper, the
life cycle cost is defined as the sum of the cost of the main components
of the power stage and the cost of the losses during the utilization
period. The semiconductor switches, output filtering, heat sink, gate
drivers, and DC link capacitance are included in the analysis, whereas
their parameters are freed in the optimization process. The behavior of
the load of an average residential customer is taken as one of the
inputs in the calculation. It is shown that parameters such as the
optimal silicon area, filter inductance, and switching frequency can
differ significantly from the industry norm in which a high weight
factor is given to the performance near the nominal power.
