<p>The object of the invention is a power supply arrangement of a conveying system and a method for controlling the power supply in a conveying system. The power supply arrangement of a conveying system comprises a controller (1) of the movement of the conveying apparatus, which controller is fitted to adjust the movement of the conveying apparatus (2) according to a determined movement reference (15,16,17); and also a frequency converter (3) with intermediate circuit, which frequency converter is connected between the power source (7) of the conveying system and the motor (8) that moves the conveying apparatus; and which frequency converter comprises a rectifying bridge (4), which is connected to the power source of the conveying system. The power supply arrangement comprises a controllable network inverter-rectifier (11 ), which is connected between the intermediate circuit (6,6') of the frequency converter and the power source (7) of the conveying system, for supplying power from the intermediate circuit to the power source. A controllable brake chopper (9) is fitted in connection with the main circuit of the frequency converter, for connecting the power resistor (10) to the main circuit of the frequency converter (3) in an electrically conductive manner.</p> |
