POWER SUPPLY ARRANGEMENT OF AN ELEVATOR

摘要

The invention relates to a power supply arrangement, a power transformer (6) and also a method for supplying power in an elevator system. The power supply arrangement of the elevator comprises an elevator motor (1), a power supply circuit (2) of the elevator, and a double-layer high-voltage ceramic capacitor (3) fitted in connection with the power supply circuit (2) of the elevator. The power transformer (6) is fitted to supply power between a first lower-voltage DC voltage (4, 4') and a second DC voltage of the double-layer high-voltage ceramic capacitor (3).
