Patent attributes
A control apparatus is provided for controlling an electric power conversion apparatus. The electric power conversion apparatus includes a reactor and a drive switch and is configured to convert one of an AC voltage and a DC voltage into the other of the AC voltage and the DC voltage. The control apparatus is configured to: acquire a current detection value that is a detected value of reactor current flowing through the reactor; acquire the AC voltage; calculate, based on the AC voltage, a command value of the reactor current; set a correction value based on the AC voltage; calculate a post-correction current detection value by subtracting the correction value from the current detection value; and operate the drive switch through peak current mode control, thereby controlling the post-correction current detection value to be in agreement with the command value.
