Title:
DRIVE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/149187
Kind Code:
A1
Abstract:
A master device (10) of a drive system (1) of an embodiment transmits, in each first cycle of a reference cycle including a plurality of first cycles, identification information of the first cycles and a first transmission synchronous signal, or transmits, in each first cycle of the reference cycle, the identification information of the first cycles, the first transmission synchronous signal, and a second transmission synchronous signal. A first drive device (31) uses the identification information to adjust the phase of a first control cycle so that the first control cycle is synchronized with a timing associated with a specific first synchronous signal among a plurality of first synchronous signals obtained by receiving the first transmission synchronous signal multiple times, and controls a first power converter. A second drive device (32) uses the identification information to adjust the phase of a second control cycle so that the second control cycle is synchronized with a timing associated with a specific second synchronous signal among a plurality of second synchronous signals obtained either by receiving the first transmission synchronous signal multiple times or by receiving the second transmission synchronous signal multiple times, and controls a second power converter.
