METHOD FOR INCREASING THE LIFETIME OF CONVERTER SWITCHES, AND SYSTEM

The disclosure relates to a method for increasing the lifetime of converter switches in a system having an energy source connected to a DC bus and a DC-to-DC converter having the converter switches. The method includes determining a system state in which electrical power of the energy source is available for which no transmission via the DC-to-DC converter and no output to further participants of the DC bus is provided, and operating the DC-to-DC converter during the determined system state such that power dissipation is generated in the DC-to-DC converter without power being transmitted via the DC-to-DC converter. A system having an energy source and a DC-to-DC converter having the converter switches is disclosed, as well as an energy-generating system having such a system.
