FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical engineering, in particular to control methods and control devices for wireless charging device. Technical result is achieved by the fact that the method includes the following stages: receiving a power adjustment value transmitted by a terminal; and adjusting at least one of the output voltage and the output frequency of the wireless AC power signal in accordance with the power adjustment value in order to adjust the output power of the wireless AC power signal.
EFFECT: technical result consists in improvement of efficiency of wireless charging for terminal with observance of changes in needs of power of battery load at terminal, and is aimed at prevention of occurrence of serious heat release during charging with high power.
