Abstract :
This paper analyses the life-cycle cost of a customer-end inverter that is used in a low voltage DC distribution system. Cost of the losses during the utilization period of the system and the investment cost of the main components is included in the study and the distribution between them is analyzed to determine the dominating cost factors. A sensitivity analysis is carried out to determine how variations in the cost of electricity, the cost of the hardware and the selected switching frequency affect the life-cycle cost.
