Title:
POWER CONVERTER AND DRIVE CONTROLLER
Document Type and Number:
WIPO Patent Application WO/2022/059106
Kind Code:
A1
Abstract:
This power converter (20) is provided with: a power conversion unit (21) which converts power generated by a generator (14) into power for supply to a load (51); a target torque calculation unit (22) which calculates the target torque of the generator (14) depending on the operation status of the load (51); and a power conversion control unit (23) which controls the power conversion unit (21) on the basis of the torque current command value and an excitation current command value for bringing the output torque of the generator (14) closer to the target torque. The absolute values of the torque current command value and the excitation current command value calculated by the power conversion control unit (23) while the generator (14) is generating power are positively correlated.
