Title:
CONTROL UNIT FOR POWER CONVERTER, AND POWER CONVERSION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/032195
Kind Code:
A1
Abstract:
By performing on/off control of a semiconductor element (SW), this control unit (50) for a power converter (20) performs switching control of switching, on the basis of a level designation signal, between a 3-level operation mode of outputting an AC voltage including a 3-level voltage in a positive electrode and a negative electrode of a DC circuit part (10), and a voltage dividing point between the positive electrode and the negative electrode of the DC circuit part, and a 2-level operation mode of outputting an AC voltage including a 2-level voltage in the positive electrode and the negative electrode of the DC circuit part (10), and switches a compensation value for compensating for an error between a voltage command and the AC voltage between the 2-level operation mode and the 3-level operation mode.
