3 is a diagram for explaining a sensing signal transmission procedure in a wireless charging system according to an embodiment of the present invention.

As an example, the wireless power transmitter may be equipped with three transmit coils 111, 112, 113. Each transmit coil may overlap a portion of the transmit coil with a different transmit coil, and the wireless power transmitter may include a predetermined sense signal 117, 127 for sensing the presence of the wireless power receiver through each transmit coil - And sequentially transmits digital ping signals in a predefined order.

As shown in FIG. 3, the wireless power transmitter sequentially transmits the detection signal 117 through the primary sensing signal transmission procedure shown in reference numeral 110, and receives a signal strength indicator (Signal Strength Indicator 116 (or signal strength packet) may be received. Subsequently, the wireless power transmitter sequentially transmits the detection signal 127 through the secondary detection signal transmission procedure shown in the reference numeral 120, and the signal strength indicator 126 is transmitted to the transmission coils 111 and 112 It is possible to control the efficiency (or charging efficiency) - that is, the state of alignment between the transmitting coil and the receiving coil - to identify a good transmitting coil and to allow power to be delivered through the identified transmitting coil, .

As shown in FIG. 3, the reason why the wireless power transmitter performs the two detection signal transmission procedures is to more accurately identify to which transmission coil the reception coil of the wireless power receiver is well aligned.

If the signal strength indicators 116 and 126 are received at the first transmission coil 111 and the second transmission coil 112 as shown in the aforementioned numerals 110 and 120 of FIG. 3, Selects a transmission coil having the best alignment based on the received signal strength indicator 126 in each of the first transmission coil 111 and the second transmission coil 112 and performs wireless charging using the selected transmission coil .

4 is a state transition diagram for explaining the wireless power transmission procedure defined in the WPC standard.

Referring to FIG. 4, power transmission from a transmitter to a receiver according to the WPC standard is largely divided into a selection phase 410, a ping phase 420, an identification and configuration phase 430, And a power transfer phase (step 440).

The selection step 410 may be a phase transition when a specific error or a specific event is detected while initiating a power transmission or maintaining a power transmission. Here, the specific error and the specific event will become clear through the following description. Also, in a selection step 410, the transmitter may monitor whether an object is present on the interface surface. If the transmitter detects that an object is placed on the interface surface, it can transition to the step 420 (S401). In the selection step 410, the transmitter transmits an analog ping signal of a very short pulse and can detect whether an object exists in the active area of the interface surface based on the current change of the transmission coil.

In step 420, the transmitter activates the receiver when an object is sensed, and transmits a digital ping to identify whether the receiver is a WPC compliant receiver. If the transmitter does not receive a response signal for the digital ping (e.g., a signal strength indicator) from the receiver in step 420, then the transmitter may transition back to the selection step 410 (S402). Also, in step 420, the transmitter may transition to a selection step 410 when receiving a signal indicating completion of power transmission from the receiver, i.e., a charging completion signal (S403).

Once the ping stage 420 is complete, the transmitter may transition to an identification and configuration step 430 to collect receiver identification and receiver configuration and status information (S404).

In the identifying and configuring step 430, the sender may determine whether the packet is unexpected, whether a desired packet is received during a predefined period of time (time out), a packet transmission error (transmission error) (No power transfer contract), the process can be shifted to the selection step 410 (S405).

Once the identification and configuration for the receiver is complete, the transmitter may transition to power transfer step 440, which transmits the wireless power (S406).

In the power transfer step 440, the transmitter determines whether an unexpected packet is received, a desired packet is received for a predefined period of time (time out), a violation of a predetermined power transmission contract occurs transfer contract violation, and if the charging is completed, the selection step 410 can be performed (S407).

In addition, in the power transfer step 440, if the transmitter needs to reconfigure the power transfer contract according to changes in the transmitter state, etc., it may transition to the identification and configuration step 430 (S408).

The power transmission contract may be set based on the status and characteristic information of the transmitter and the receiver. For example, the transmitter status information may include information on the maximum amount of transmittable power, information on the maximum number of receivable receivers, and the receiver status information may include information on the requested power and the like.

5 is a state transition diagram for explaining a wireless power transmission procedure defined in the PMA standard;

Referring to FIG. 5, power transmission from a transmitter to a receiver according to the PMA standard is largely divided into a standby phase 510, a digital ping phase 520, an identification phase 530, A Power Transfer Phase 540, and an End of Charge Phase 550. FIG.

The waiting step 510 may be a step of performing a receiver identification procedure for power transmission or transitioning to a specific error or a specific event while sensing a power transmission. Here, the specific error and the specific event will become clear through the following description. Also, at a standby step 510, the transmitter may monitor whether an object is present on the Charging Surface. If the transmitter detects that an object has been placed on the charging surface, or if an RXID retry is in progress, the digital switching may proceed to step 520 (S501). Here, RXID is a unique identifier assigned to a PMA compatible receiver. At the standby step 510, the transmitter transmits an analog ping of a very short pulse and, based on the change in current of the transmitting coil, causes the object to move to the active surface of the interface surface-for example, It can be detected whether or not it exists.

The transmitter transited to the digital pinging step 520 sends a digital finger signal to identify whether the sensed object is a PMA compatible receiver. When sufficient power is supplied to the receiver by the digital ping signal transmitted by the transmitter, the receiver can modulate the received digital ping signal according to the PMA communication protocol and transmit a predetermined response signal to the transmitter. Here, the response signal may include a signal strength indicator indicating the strength of the power received at the receiver. At step 520, the receiver can transition to the identification step 530 if a valid response signal is received (S502).

If the response signal is not received or it is determined that it is not a PMA compliant receiver, i.e., it is a Foreign Object Detection (FOD), at step 520, the transmitter can transition to the wait step 510 (S503). As an example, a foreign object (FO) may be a metallic object including coins, keys, and the like.

In the identifying step 530, the transmitter may transition to the wait step 510 if the receiver identification procedure fails or the receiver identification procedure must be re-performed and the receiver identification procedure has not been completed for a predefined period of time S504).

If the transmitter succeeds in identifying the receiver, the transmitter may transition from the identifying step 530 to the power transfer step 540 and start charging (S505).

In the power transfer step 540, the transmitter determines if the desired signal is not received within a predetermined time (Time Out), an FO is detected, or if the voltage of the transmit coil exceeds a predefined reference value, (S506).

Also, in the power transmission step 540, if the temperature sensed by the temperature sensor provided inside the transmitter exceeds a predetermined reference value, the transmitter may transition to the completion of charging step 550 (S507).

In the charge completion step 550, if the transmitter is confirmed that the receiver has been removed from the charging surface, the transmitter can transition to the standby state 510 (S509).

If the measured temperature drops below the reference value in the over temperature state, the transmitter may transition from the charging completion step 550 to the digital charging step 520 in step S510.

In the digital ping phase 520 or the power transfer phase 540, the transmitter may transition to the charge completion phase 550 (S508 and S511) when an End Of Charge (EOC) request is received from the receiver.
