Title:
BRUSHLESS MOTOR CONTROL DEVICE AND POWER SUPPLY CONVERSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/026658
Kind Code:
A1
Abstract:
A brushless control device 10 for controlling the rotation of a brushless motor 11 is provided with a rectifier circuit 20 and a switching circuit 30. In the rectifier circuit 20, regardless of which terminal between a first rectifier circuit input terminal 21-1 and a second rectifier circuit input terminal 21-2 has a high potential, the first rectifier circuit output terminal 22-1 has a higher potential than the second rectifier circuit output terminal 22-2. The switching circuit 30 generates voltage of a pattern that rotates the brushless motor 11 in a first direction when the first rectifier circuit input terminal 21-1 has a higher potential than the second rectifier circuit input terminal 21-2, and generates voltage of a pattern that rotates the brushless motor 11 in a second direction that is the opposite rotation of the first direction when the second rectifier circuit input terminal 21-2 has a higher potential than the first rectifier circuit input terminal 21-1.
