CONTROL METHOD AND SYSTEM FOR DYNAMIC LOAD SWITCHING

摘要

A control method and system for dynamic load switching, wherein a transmitting terminal (501) uses soft switching to control a resonant circuit; when a receiving terminal (502) is about to execute line load (503) switchover, sending communications information to transmitting terminal (501); when transmitting terminal (501) receives communications information sent by receiving terminal (502), adjusting, according to the communications information, the control parameters of transmitting terminal (501) and, within a first preset time period, using hard switching to control the resonant circuit; within the first preset time period (T1), receiving terminal load (503) completing the corresponding switch; the communications information comprising the switch command to be executed by load (503 ); the first preset time period instructing transmitting terminal 501) to receive communications information until hard switching control ends. Using a combination of soft switching and hard switching to control a resonant circuit eliminates the impact had on a resonant system by a sudden change of receiving terminal load, thereby improving system stability and security while ensuring highly efficient transmission.
