Title:
POWER CONVERSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/033295
Kind Code:
A1
Abstract:
This power conversion device is provided with: a switching circuit (200) for outputting an output voltage in response to an input voltage; a signal generation unit (6) for generating, on the basis of a first command value (D*), a switching signal for a switching element included in the switching circuit; a current control unit (3) configured so as to generate a second command value on the basis of the deviation between a current target value and the current flowing through the switching circuit so that the current flowing through the switching circuit approaches the current target value; an operation mode detection unit (4) configured so as to detect an operation mode of the switching circuit on the basis of the first command value (D*); and a compensation unit (5) for adjusting the second command value so as to compensate a gain that is the ratio between the deviation and the variation of the current flowing through the switching circuit. The compensation unit (5) is configured so as to adjust the second command value so as to suppress the variation of the gain on the basis of the operation mode detected by the operation mode detection unit and output the first command value.
