Abstract:
A wireless charging reception system and control method capable of adjusting resonance frequency are disclosed. According to an embodiment of the present disclosure, a wireless charging reception system capable of adjusting the resonance frequency may include a resonance circuit unit including a circuit in which a resonance inductor and a resonance capacitor are connected in parallel; a transmission circuit unit including a transmission inductor and a power supply voltage unit adjacent to the resonance inductor within a threshold distance; a switch unit connected in parallel with the resonance circuit unit and including at least one switch; a rectifier circuit connected in parallel with the switch unit and the resonance circuit unit; and a control unit that controls a phase of transmission current flowing through the transmission inductor generated through the power voltage unit to be same as a phase of current associated with the at least one switch.
