Title:
POWER CONVERSION CONTROL METHOD AND POWER CONVERSION CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/171514
Kind Code:
A1
Abstract:
Provided is a power conversion control method comprising: calculating a pre-switching pulse time that is the time from a first conductive state switching timing, which is the conductive state switching timing of a second bridge circuit immediately before a predetermined carrier wave switching timing, to the carrier wave switching timing; calculating a post-switching pulse time that is the time from the carrier wave switching timing to a second conductive state switching timing, which is an initial conductive state switching timing after the carrier wave switching timing; when the conductive state of the second bridge circuit is not switched at the carrier wave switching timing, determining that carrier wave switching is impossible if the sum of the pre-switching pulse time and the post-switching pulse time is less than a predetermined pulse time sum threshold value; and when the conductive state of the second bridge circuit is switched at the carrier wave switching timing, determining that carrier wave switching is impossible if the pre-switching pulse time or the post-switching pulse time is less than a predetermined pulse time threshold value.
