Title:
PROPULSION CONTROL DEVICE AND FILTER CAPACITOR VOLTAGE CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2023/286122
Kind Code:
A1
Abstract:
A propulsion control device (100) comprises a control unit (10) for performing mode switching control and power consumption control, wherein: said mode switching control switches between an asynchronous mode and a synchronous mode on the basis of a filter capacitor voltage and a main electric motor speed; and said power consumption control causes regenerative power generated when a main electric motor (9) operates as a generator to be consumed at a power consumption resistor (52) of a brake chopper circuit (5). The control unit (10) changes the target value of the filter capacitor voltage controlled by the power consumption control, thereby controlling an operation point at which the asynchronous mode and the synchronous mode are switched to each other to a desired position.
