The invention concerns an electricity supply device (1, 2, 3) for supplying electric power in an elevator system. The electricity supply device (1, 2, 3) comprises a controllable power output stage (4, 5) which in turn comprises a connection to a load of the elevator system to be supplied, and a control circuit (18, 27) for controlling the drive device (6, 7) of the elevator. The invention is characterized in that the power output stage (4, 5) comprises one or more controllable solid-state switches (9) in the form of silicon carbide (SiC) solid-state switches, wherein a thermal barrier (19) is made between the aforementioned one or more silicon carbide solid-state switches (9) of the power output stage (4, 5) and the control circuit (18, 27) for reducing the thermal flow occurring from the silicon carbide solid-state switch/silicon carbide solid-state switches (9) to the control circuit (18, 27).
