Abstract
A power control method for wireless charging and an electronic device therefor are provided. The electronic device, includes a coil, an inverter including gate inputs which are electrically connected to the coil, and at least one processor. The at least one processor is configured to control the gate inputs of the inverter in an anti symmetric manner to generate an output power, receive an output power reduction request from an external electronic device, based on receiving the output power reduction request, determine whether a ratio of ON-operations to OFF-operation of the gate inputs of the inverter is less than or equal to a designated ratio, and based on the ratio of ON-operations to OFF-operations of the gate inputs of the inverter being less than or equal to the designated ratio, modulate a phase of a voltage input into the gate inputs of the inverter to generate an output power.
