Method for automatically adjusting power in high power inductive power supply

The invention provides a method for automatically adjusting power in a high-power inductive power supply, in particular, a power signal can be transmitted through an inductive method for power adjustment, and when the power supply module and the power receiving module synchronously transmit power and data signals, the power supply mode After the group senses the data signal, it automatically analyzes, processes and automatically adjusts the power.

The inductive power supply (or wireless charger) currently available on the market utilizes two coils, one of which serves as the power supply terminal for transmitting power and the other as the power receiving terminal for receiving power, due to wireless power. The energy is dangerous and will heat the metal object. The principle is like the induction cooker, which also affects the phenomenon that the object to be charged is easily damaged or malfunctioned due to heat.

In the inductive power supply, in order to operate safely, the power supply end and the power receiving end must be able to recognize each other before the power supply can be started. That is, under the demand of such a function, it is necessary to establish a control data code at the power supply end and the power receiving end. The method of transmission, and the transmission function of the data code must be quite stable, so that the power transmission can be stably operated, and in the conventional inductive charging system, the inductive power supply can only be between the power supply coil and the power receiving coil, only It can operate at a fixed distance. When the relative distance of the coil changes, the power supply output power cannot be effectively changed so that the power receiving end can receive stable energy. Therefore, there is a limit that cannot be transmitted when the distance of the relative position of the coil changes. In addition, in the high-power inductive power supply, the output power will increase the power or reduce the power demand due to the change of the output demand of the power receiving terminal, and the power demand of the receiving end needs to be adjusted by the wireless sensing mode. There is no physical signal line connection, so it will be quite difficult to control.

Therefore, how to solve the problem of safe transmission of power when the conventional electronic device is inductively transmitting power and the limited sensing range of the coil, and the power cannot be changed according to the demand of the receiving end when the power is supplied, so that the transmission power is too large, resulting in inefficiency or transmission power. Too small to suffer from the lack of output of the terminal, that is, the relevant manufacturers in this industry are eager to study the direction of improvement.

Therefore, in view of the above-mentioned problems and deficiencies, the inventors have collected relevant information, and through various evaluations and considerations, and through years of experience in the industry, through continuous trial and modification, this type of electronic device induction has been developed. When the power is transmitted, the data signal is transmitted through the inductive method for power adjustment. When the power supply module and the power receiving module synchronously transmit power and data signals, the power supply module automatically detects, processes, and automatically adjusts the power after receiving the data signal. The birth of the invention patent for the method of automatic power adjustment in high-power inductive power supplies.

The main purpose of the present invention is that the power supply module and the power receiving module of the power supply device transmit power and transmit data signals through the power supply coil and the power receiving coil, and are electrically connected to the power receiving microprocessor of the power receiving module.

If the signal is unclear, it indicates that the power receiving module 2 is still within the sensing range, that is, the step (1062) is performed, and if there is no signal at all, the power receiving module 2 is far away. That is, step (1064) is performed.

(107) comparing the voltage of the power supply 161 and the voltage of the power receiving detection terminal 222 (the two values in the preferred embodiment may use the same 8-bit recording format, and may also be other equivalent bit recording formats), If the power detection terminal 222 has a large voltage value, that is, step (11071) is performed, if the power supply 161 has a large voltage value, step (108) is performed.

(114) After the power adjustment is completed, the power supply timer in the power supply microprocessor 11 of the power supply module 1 is filled in the initial time constant, and step (104) is performed.

The step of automatically adjusting the power is mainly to convert the voltage state of the power receiving detection terminal 222 of the power receiving module 2 into a voltage value signal to the power supply module 1, and the voltage value of the power supply 161 of the power supply module 1 Compared with the voltage value of the detecting end point 22, the working frequency and the output power are automatically adjusted to achieve the purpose of receiving the stable power supply by the power receiving module 2.

In the high-power inductive power supply, the power automatic adjustment system power supply module 1 can change according to the output power demand of the power receiving module 2, and the output power is adjusted to be large or small, since the power supply module 1 and the power receiving module 2 have no physical circuit. The connection is transmitted through the induction coil, and a mechanism for controlling the data transmission must be established between the power supply module 1 and the power receiving module 2, and the power supply module 1 receives the data signal transmitted by the power receiving module 2 inductively. Regardless of whether the charging operation flow is executed to any step, the power supply microprocessor 11 of the power supply module 1 will preferentially perform the analysis and processing of the data signal, and after the data signal processing is completed, return to the original charging operation step to reach the power supply mode. The group 1 and the power receiving module 2 do not affect the charging operation when performing synchronous operation of power supply and data transmission.

Please refer to the first, second and eighth figures, which is a simplified circuit diagram of the power supply module of the present invention, a simple circuit diagram of the power receiving module, and an automatic power adjustment frequency diagram. As can be clearly seen from the figure, the present invention During the process of inductively transmitting power between the power supply module 1 and the power receiving module 2, the power received by the power receiving module 1 changes with the relative distance between the power feeding coil 171 and the power receiving coil 281, and the receiving mode becomes longer when the relative distance becomes longer. The power received by the group 2 will become smaller, and the power received by the power receiving module 2 will become larger when the relative distance is closer; and the power output of the power supply module 1 must be constantly changed in order to stabilize the receiving module 2. When the distance becomes longer, the power received by the power receiving module 2 becomes smaller, and the power supply module 1 increases the power output to stabilize the power received by the power receiving module 2, and vice versa to reduce the output of the power supply module 1 Power adjustment.

In practice, the terminal voltages of the power supply module 1 and the power receiving module 2 are respectively used as the power measurement points, and the power supply 16 of the power supply module 1 is compared with the power supply module 16 to detect the end point and the power receiving mode in the program flow. The group 2 detects the end point 222 and performs the comparison adjustment completion function; the other purpose of the design is to use the voltage comparison between the power supply module 1 and the power receiving module 2, when the power supply voltage of the power supply module 1 is increased. The stability value set by the receiving power of the power receiving module 2 is improved, and the method can effectively stabilize the data code transmission state of the power supply module 1. In the operating characteristics of the inductive power supply, the power supply 16 and the power receiving in the power supply module 1 When the voltage sensed by the module 2 is close, high transmission efficiency and stable data code transmission can be obtained, and the voltage of the power receiving output terminal is processed by the DC buck, so the output voltage remains constant.

In the process of automatic adjustment of the power supply, the voltage data signal transmitted by the power receiving module 2 is sent to the power supply module 1 for analysis and comparison, and the power output is adjusted, but the relative distance between the power supply coil 171 and the power receiving coil 281 is changed. The data code that is clear enough for identification cannot be fed back, or the power of the power receiving output suddenly increases, which may cause the unclear data code to be unresolved, but this condition is that the power supply coil 171 and the power receiving coil 281 are still in the sensing range; In the power supply automatic adjustment program, the operating mechanism is arranged for this situation. When the power supply module 1 receives an unclear data code indicating that the induction coil is still in range, the energy output from the power supply module 1 is increased to be powered. Module 2 can receive more power to stabilize the output of power receiving module 2 when the relative distance becomes longer or the power demand becomes higher. If power supply module 1 does not receive the data code at all, it indicates that power receiving module 2 has If it is far away, the output of the power supply module 1 is immediately cut off.

The protection mechanism of the power receiving module 2 is arranged to stop the transmission of the data code and cut off the output of the power receiving module 2 to protect the back end device from being excessively high when the voltage of the power receiving detecting terminal 222 is too high. Damaged, when the power receiving module 2 stops transmitting, it will be judged that the device is far away from the power supply module 1, and the power transmission will be cut off immediately. Under this arrangement, the power receiving module 2 will not be unclear in the data transmission. Under the condition, the power module 1 does not increase the power output and damages the components on the power receiving module 2.

The protection mechanism on the power supply module 1 is to limit the maximum power output by detecting the amplitude of the power supply coil 171 to avoid damage to the parts. The output power is changed by the frequency variation on the power supply driving unit 12 to change the amplitude output on the power supply coil 171; In the program initialization, the maximum amplitude limit is defined. When the frequency is decreased and the amplitude is increased, if the amplitude is detected to have reached the upper limit, the frequency will be stopped, and the upper limit will be preset according to the circuit demand, but at high power. In the case of inductive power supply, the amplitude of the power supply coil 171 may be reduced by the coupling of the power receiving coil, so that in some cases, the frequency may have reached the maximum resonance point, but the preset upper limit has not been reached and the frequency is stopped. Decreasing the amplitude after the frequency passes through the maximum resonance point will cause the power to become smaller, so there is another mechanism to check the amplitude change of the coil once the frequency is lowered, and the amplitude is reduced if the frequency is reduced. That is to say stop to reduce the frequency, this mechanism will complete the coupling in different coils And can automatically adjust the power protection circuit will not output excessive power from being damaged.

Therefore, the above description is only a preferred embodiment of the present invention, and is not limited to the patent scope of the present invention. The method for automatically adjusting the power of the high-power inductive power supply of the present invention is powered by the power supply module. The processor, the power automatic adjustment program built in the power receiving module of the power receiving module, can achieve the purpose, so that the power receiving module can automatically adjust the power output of the power supply module under the change of the sensing distance and the power demand, so that the power module can automatically adjust the power output of the power supply module. The high-power inductive power supply can transmit stable power to the power receiving module, and establish a complete protection mechanism for the power supply module and the power receiving module, so that the circuit will not be damaged due to excessive power, and the utility model can achieve the aforementioned effects. The process, the implementation method, and the like, and related equipment and devices are all covered by the present invention. Such simple modifications and equivalent structural changes are all included in the scope of the patent of the present invention and are combined with Chen Ming.
