Title:
LOAD DRIVING SYSTEM AND LOAD DRIVING METHOD
Document Type and Number:
WIPO Patent Application WO/2018/179483
Kind Code:
A1
Abstract:
A load driving system for driving a load to which power is supplied from a power line comprises a control unit that controls switching between the power line and the load, and a communication unit that performs communication by use of a voltage and a current of the power line. The control unit, when performing the switching, controls the timing of performing the switching on the basis of the width of a transition period of the current of the power line due to the switching, in such a manner that the transition period is moved away from the center of a period corresponding to a symbol communicated by the communication unit.
