摘要： Disclosed herein is a wireless charging system that includes a transmission device including a primary coil and a reception device including a secondary coil, wherein the transmission device detects an input signal provided from the primary coil to generate an output signal in the form of a pulse, and compares the level of the generated output signal with a reference voltage to generate a detection signal for determining the presence or absence of the reception device. The wireless charging system does not require an analog-to-digital converter (ADC), eliminating the necessity of using an ADC chip or a high-priced control circuit including an ADC block, thus reducing a material cost of the system. In addition, since the wireless charging system does not require a software algorithm for processing an ADC signal, the performance can be improved.

The transmission unit is configured to generate a wireless power signal to be transmitted, transmit the wireless power signal using magnetic resonance, receive a reflected wireless power signal from a wireless power reception unit, determine whether a load device is present, and transmit a further wireless power signal when it is determined that the load device is present in such a way that impedance and output power depending on variation in a distance to the load device are tracked, and wireless power is supplied to the load device in an optimized state. Accordingly, a separate transceiver module is not provided for the purpose of performing communication between a transmitting end and a receiving end, and a reception environment is automatically detected, thus enabling wireless power to be transmitted in an optimal wireless power transmission state.
