Title:
CONTROL DEVICE, DC/DC CONVERSION DEVICE, AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2023/166606
Kind Code:
A1
Abstract:
A control device (8) of a DC/DC converter (4) includes: a low-pass filter (10) that executes low-pass filter processing on an output voltage of the DC/DC converter (4); an operation control unit (50) that controls the operation of the DC/DC converter (4) so as to cause the output voltage subjected to the low-pass filter processing to follow a command value; a generation unit (31) that generates a first transfer function for the DC/DC converter (4) so as to simulate a frequency characteristic of the output voltage of the DC/DC converter (4); and a setting unit (33) that sets a cutoff frequency of the low-pass filter (10) on the basis of a first frequency range where the difference between the frequency characteristic of the output voltage of the DC/DC converter (4) and a frequency characteristic of the first transfer function is equal to or less than an acceptable value.
