The learning module 110 may perform learning for the design of the wireless charging system in the present invention. Depending on the design, the shape and arrangement information of each component included in the wireless charging system can be obtained. Of course, in the case of the coil, other information such as the number of rotations may be included. In the following description, information obtained through learning is referred to as 'learning design information'.

The learning module 110 may include at least one engine. The wireless charging system to be designed includes a core. The wireless charging system may include at least one of a coil, a substrate, and a secondary battery. Preferably, the design device can design at least two of a core, a coil, a substrate, and a secondary battery. More preferably, the design device may design a core, a coil, and a substrate. Most preferably, the design device may design a core, a coil, a substrate, and a secondary battery.

In the embodiment, after designing the core, the coil, and the substrate, the arrangement of the secondary battery in the remaining space is exemplified.

The learning module 110 may include a second learning module 111 that generates the learning design information by learning based on input information.

The analysis module 120 may provide the performance evaluation result to the first learning module 112 after evaluating the wireless power transmission performance based on the learning design information provided from the second learning module 111 . .

The analysis module 120 can analyze magnetic flux density, transmission coil inductance, reception coil inductance, mutual inductance between transmission and reception units, coupling coefficient, transmission coil resistance, reception coil resistance, reception power, and system efficiency, etc., in addition to , if it is a parameter that can affect the performance of the wireless charging system, it can be the subject of analysis.

When the analysis module 120 evaluates the performance of the wireless charging system, various types of simulation programs may be used, for example, programs such as ANSYS Maxwell, PSIM, and SNSYS Simplorer may be used.

The first learning module 112 may perform learning on the design information by reflecting the information from the analysis module 120 . The first learning module 112 may adjust the control variable according to the learning result. The first learning module 112 may output an adjustment control variable to the second learning module 111 .

The learning module 110 may perform learning of design information using, for example, a Q-learning algorithm, which is one of reinforcement learning, and may generate design information according to an E-greedy policy.

The output unit may output the learning design information of the result of the second learning module 111 and the analysis result of the analysis module 120 .

As learning of the learning module 110 is performed, values of components in the design information may be changed, for example, an initial value ('0') is changed to a set value ('1'), and a set value ('1') may be changed to an initial value ('0').

Briefly, the operation of the electronic drug wireless charging system design device will be described.

In the initial stage of learning, the second learning module 111 performs learning based on the initial control variable, and generates the learning design information as a result of learning execution. The learning design information is provided to the analysis module 120 .

The analysis module evaluates the performance of the wireless charging system corresponding to the learning design information, and outputs a performance evaluation result including compensation information to the first learning module 112 .

The first learning module 112 reflects the performance evaluation result from the analysis module 120 to learn about the previous learning design information. The first learning module 112 may adjust the control variable in a direction to increase the reward based on the reward information. The first learning module 112 may output the adjusted control variable to the second learning module 111 .

The second learning module 111 generates new learning design information, and the newly created learning design information is provided to the analysis module 120 again.

After performing the learning operation, the second learning module 111 may perform an operation for determining whether a condition for terminating the learning operation is satisfied. For example, the learning module 110 may count the number of times of performing learning after performing learning, and may end the learning operation when the number of times of performing learning reaches a preset maximum number of learning executions. As another example, the learning module 110 may compare the previous performance evaluation result with the current performance evaluation result, and if the difference between the two results is within a set range, the learning operation may be terminated. Of course, it can also be terminated in other ways.

The control variable will be described.

The control variable may include three control variables. The first control variable may have a coil shape. The coil shape may include a circle and a quadrangle. The second control variable may include an outer diameter, an inner diameter, and a number of rotations of the coil. The third control variable may include a coil position.

When only the first, second, and third control variables are provided, the coil may be provided as learning design information. As the remaining components of the wireless charging system, the substrate, the core, and the secondary battery may be arranged according to the arrangement of the coil. For example, in the case of a core, it may be arrange|positioned in the center of a coil. In the case of the substrate, the coil and a predetermined height may be overlapped and disposed. The secondary battery may be disposed in a final surplus space after the arrangement of the coil, the core, and the substrate is completed.

In addition, all of the first, second, third, fourth, and fifth control variables may be provided as the initial control variable. Another variable may be added as the adjustment control variable. In this case, together with the control parameters for the coil shown in FIG. 4 , the control parameters for the substrate and the core may be applied together.

When the coil is arranged to be small, it may be provided together with the flat portion and the curved portion.

In other words, the secondary battery is arranged according to the shape of the surplus space after the arrangement of the substrate, the coil, and the core is finished. The secondary battery does not require large capacity and size. Since the secondary battery of the embodiment is free to charge, it may not be strictly required that the secondary battery has a large capacity.

Meanwhile, as another embodiment of the present invention, the first and second learning modules 111 and 112 may be performed by a single learning module. However, in that case, there is a fear that learning may not be performed smoothly due to insufficient system capacity for performing two tasks with different functions.

According to the present invention, it is possible to design a wireless charging system inside the electronic drug with high performance.
