Title:
OVERLOAD STATE SELF-ADJUSTING CONTACTLESS POWER SUPPLIER
Document Type and Number:
WIPO Patent Application WO/2024/136055
Kind Code:
A1
Abstract:
The present invention relates to an overload state self-adjusting contactless power supplier comprising: a high frequency inverter (HFI) provided at a track; a regulator provided at a carrier; a motor driving unit, which receives output of the regulator so as to accelerate a carrier motor and drive same while maintaining a final speed; and a motion controller for calculating the driving acceleration and the final speed instruction value of the carrier motor and transmitting same to the motor driving unit, and thus, if output current of the HFI reaches an overload state, the output current is controlled to be decreased and, if input voltage (Vdc_in) of a DC/DC converter decreases in response to a decrease in output current of an AC/AC inverter, the motion controller calculates driving acceleration and a final speed limitation value of the carrier motor, which are associated with the input voltage, so as to transmit same to the motor driving unit, thereby actively alleviating the overload state. According to the present invention, the provided overload state self-adjusting contactless power supplier actively alleviates an overload at each carrier if there is an overload in an HFI of a corresponding track caused by an overload during failover due to an HFI failure of a track or by congestion of carriers in a specific track from among electrically-separated tracks.
