Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0033] See also Figure 1 and Figure 2 , a power control circuit for an AI device, comprising:

[0034] The power processing module is used to introduce the DC power supply VCC and supply power to the voltage stabilizing output module through the first switch tube;

[0035] The fluctuation regulation module is used to adjust the conduction state of the first switch tube based on the size of the DC power supply VCC, so as to realize the integration of the soft start protection circuit and the overvoltage protection circuit;

[0036] The voltage-stabilizing output module is used to output a stable voltage through the second switch tube to supply the electrical equipment;

[0037] The first output end of the power processing module is connected to the input end of the fluctuation regulation module, the output end of the fluctuation regulation module is connected to the input end of the power processing module, and the second output end of the power processing module is connected to the input end of the voltage stabilization output module.

[0038] In this example: See Figure 1 , the power processing module includes:

[0039] The sampling output submodule is used to sample the DC power supply VCC, obtain the sampled voltage and output it to the fluctuation regulation module;

[0040] The conduction control submodule is used to introduce the DC power supply VCC, which supplies power to the voltage stabilizing output module after passing through the first switch tube; a manual switch is set;

[0041] The output end of the sampling output submodule is connected to the input end of the fluctuation regulation module, the input end of the conduction control submodule is connected to the output end of the fluctuation regulation module, and the output end of the conduction control submodule is connected to the input end of the voltage stabilization output module.

[0042] In this example: See Figure 1 The sampling output submodule includes a first capacitor C1, a second capacitor C2, a first resistor R1, a second resistor R2, a third resistor R3, and a first diode D1. One end of the first capacitor C1 is connected to one end of the second capacitor C2, one end of the first resistor R1, one end of the third resistor R3, and a DC power supply VCC. The other end of the first capacitor C1 is grounded, the other end of the second capacitor C2 is grounded, the other end of the first resistor R1 is connected to one end of the second resistor R2 and the input end of the fluctuation regulation module, the other end of the second resistor R2 is grounded, the other end of the third resistor R3 is connected to the cathode of the first diode D1 and the input end of the fluctuation regulation module, and the anode of the first diode D1 is grounded.

[0043] The DC power supply VCC is input, and the DC power supply VCC (common point A) is sampled through the first resistor R1 and the second resistor R2, and the sampled voltage is output to the fluctuation regulation module. The reference voltage (common point B) is obtained through the third resistor R3 and the first diode D1, and output to the fluctuation regulation module.

[0044] In another embodiment, the first capacitor C1 and the second capacitor C2 can be omitted. The first capacitor C1 and the second capacitor C2 are used for filtering to ensure a stable power supply.

[0045] In this example: See Figure 1The conduction control submodule includes a first switch S1, a second diode D2, a fourth resistor R4, a first transistor V1, and a second MOS transistor V2. The S pole of the second MOS transistor V2 is connected to one end of the first switch S1 and the DC power supply VCC, the other end of the first switch S1 is connected to the positive pole of the second diode D2, the negative pole of the second diode D2 is connected to one end of the fourth resistor R4 and the base of the first transistor V1, the other end of the fourth resistor R4 is grounded, the emitter of the first transistor V1 is grounded, the collector of the first transistor V1 is connected to the G pole of the second MOS transistor V2 and the output end of the fluctuation regulation module, and the D pole of the second MOS transistor V2 is connected to the input end of the voltage stabilization output module.

[0046] After receiving the control signal of the fluctuation regulation module (common point C), the second MOS tube V2 is turned on. The first switch S1 can be manually controlled to control the first transistor V1 to turn on, lowering the G pole voltage of the second MOS tube V2, so that the second MOS tube V2 is turned on.

[0047] In another embodiment, a light emitting diode may be additionally provided to detect whether the first transistor V1 is turned on and determine whether the first switch S1 is closed.

[0048] In this example: See Figure 2 , the fluctuation regulation module includes:

[0049] The differential amplifier submodule is used to obtain a differential amplification signal based on the sampled voltage of the DC power supply VCC and a preset reference voltage, and output it to the PWM signal submodule;

[0050] The PWM signal submodule is used to adjust the duty cycle of the output PWM signal based on the received differential amplified signal to change the conduction state of the first switch tube;

[0051] The input end of the differential amplifier module is connected to the first output end of the power processing module, the output end of the differential amplifier module is connected to the input end of the PWM signal submodule, and the output end of the PWM signal submodule is connected to the input end of the power processing module.

[0052] In this example: See Figure 2The differential amplifier submodule includes an eighth resistor R8, a ninth resistor R9, a tenth resistor R10, an eleventh resistor R11, a first amplifier U1, a thirteenth resistor R13, and a sixth capacitor C6. One end of the eighth resistor R8 is connected to the first output end of the power processing module, one end of the ninth resistor R9 is connected to the first output end of the power processing module, the other end of the eighth resistor R8 is connected to the inverting end of the first amplifier U1 and one end of the tenth resistor R10, the other end of the tenth resistor R10 is connected to the output end of the first amplifier U1 and one end of the thirteenth resistor R13, the other end of the ninth resistor R9 is connected to one end of the eleventh resistor R11 and the in-phase end of the first amplifier U1, the other end of the eleventh resistor R11 is grounded, the other end of the thirteenth resistor R13 is connected to one end of the sixth capacitor C6 and the input end of the PWM signal submodule, and the other end of the sixth capacitor C6 is grounded.

[0053] When the DC power supply VCC fluctuates, the voltage difference between the common points A and B changes, so that the output differential signal is filtered by the sixth capacitor C6 and then output to the PWM signal submodule after passing through the differential amplifier circuit (the eighth resistor R8, the ninth resistor R9, the tenth resistor R10, the eleventh resistor R11, and the first amplifier U1 communicate to form a differential amplifier circuit, where the ratio of the eighth resistor R8 to the tenth resistor R10 is equal to the ratio of the ninth resistor R9 to the eleventh resistor R11). The larger the DC power supply VCC, the larger the output differential signal, and the smaller the DC power supply VCC, the smaller the output differential signal.

[0054] In another embodiment, the sixth capacitor C6 and the thirteenth resistor R13 may be omitted, which may result in the output differential signal being less stable.

[0055] In this example: See Figure 2 The PWM signal submodule includes a second inverter U2, a third inverter U3, a twelfth resistor R12, and a fifth capacitor C5. The power supply end of the second inverter U2 is connected to the output end of the differential amplifier submodule, the input end of the second inverter U2 is connected to one end of the twelfth resistor R12 and one end of the fifth capacitor C5, the other end of the fifth capacitor C5 is grounded, the output end of the second inverter U2 is connected to the other end of the twelfth resistor R12 and the input end of the third inverter U3, and the output end of the third inverter U3 is connected to the input end of the power processing module.

[0056] Initially, the fifth capacitor C5 has no voltage, the input end of the second inverter U2 is at a low level, the output end of the second inverter U2 outputs a high level, and the fifth capacitor C5 is charged through the twelfth resistor R12. As the fifth capacitor C5 is charged, the input end of the second inverter U2 is at a high level, the output end of the second inverter U2 outputs a low level, and the fifth capacitor C5 is discharged through the twelfth resistor R12 and becomes a low level again, and so on and so forth. A PWM signal is formed at the output end of the second inverter U2. Since the power supply of the second inverter U2 is supplied by the differential signal, the differential signal is The larger the high level outputted from the output end of the second inverter U2, the shorter the charging time of the fifth capacitor C5, and vice versa, the longer the charging time of the fifth capacitor C5, so the larger the differential signal, the smaller the PWM signal duty cycle, the smaller the differential signal, the larger the PWM duty cycle; after passing through the third inverter U3, the larger the differential signal, the larger the PWM signal duty cycle, the smaller the differential signal, the smaller the PWM duty cycle, based on the second MOS tube V2 being a PMOS tube, that is, the larger the differential signal, the lower the conduction frequency of the second MOS tube V2, the smaller the differential signal, the higher the conduction frequency of the second MOS tube V2. The larger the DC power supply VCC, the lower the conduction frequency of the second MOS tube V2, the smaller the DC power supply VCC, the higher the conduction frequency of the second MOS tube V2. In this way, the soft start protection circuit and the overvoltage protection circuit are integrated, ensuring that under the fluctuation condition of the DC power supply VCC, a voltage with less fluctuation is output to the voltage stabilizing output module to maintain the working requirements of the voltage stabilizing output module.

[0057] In another embodiment, other devices such as a 555 timer may be used to generate a PWM signal.

[0058] In this example: See Figure 1 , the voltage regulated output module includes:

[0059] The voltage output submodule is used to output voltage to supply the electrical equipment through the second switch tube;

[0060] The feedback regulation submodule is used to sample the output voltage of the second switch tube, obtain a feedback signal, and feedback the output voltage of the voltage output submodule based on the feedback signal to construct a regulated voltage output;

[0061] The first input end of the voltage output submodule is connected to the second output end of the power processing module, the output end of the voltage output submodule is connected to the input end of the feedback regulation submodule, and the output end of the feedback regulation submodule is connected to the second input end of the voltage output submodule.

[0062] In this example: See Figure 1The voltage output submodule includes a fifth resistor R5, a third MOS tube V3, a fourth triode V4, a seventh resistor R7, and a fourth capacitor C4. The D pole of the third MOS tube V3 is connected to one end of the fifth resistor R5 and the second output end of the power processing module. The other end of the fifth resistor R5 is connected to the G pole of the third MOS tube V3, the collector of the fourth triode V4, and the output end of the feedback regulation submodule. The S pole of the third MOS tube V3 is connected to one end of the seventh resistor R7 and the base of the fourth triode V4. The emitter of the fourth triode V4 is connected to the other end of the seventh resistor R7, one end of the fourth capacitor C4, and the input end of the feedback regulation submodule. The other end of the seventh resistor R7 is grounded, and the other end of the fourth capacitor C4 is grounded.

[0063] After the voltage is input, the G terminal of the third MOS tube V3 is at a high level through the fifth resistor R5, the third MOS tube V3 is turned on, and the voltage passes through the third MOS tube V3, the seventh resistor R7, and the fourth capacitor C4 to output the voltage VOUT.

[0064] In another embodiment, the fourth transistor V4 can be omitted. The fourth transistor V4 plays a role of current expansion here, making the output current larger.

[0065] In this example: See Figure 1 The feedback regulation submodule includes a first potentiometer RP1, a sixth resistor R6, a third capacitor C3, and a controllable precision voltage regulator Z1. One end of the first potentiometer RP1 is connected to the output end of the voltage output submodule, and the other end of the first potentiometer RP1 is connected to one end of the sixth resistor R6, one end of the third capacitor C3, and a reference electrode of the controllable precision voltage regulator Z1. The other end of the sixth resistor R6 is grounded, and the other end of the third capacitor C3 is grounded. The positive electrode of the controllable precision voltage regulator Z1 is grounded, and the negative electrode of the controllable precision voltage regulator Z1 is connected to the second input end of the voltage output submodule. The model of the controllable precision voltage regulator Z1 is TL431.

[0066] The output voltage VOUT is sampled through the first potentiometer RP1 and the sixth resistor R6, and fed back to the reference electrode voltage of the controllable precision voltage stabilizing source Z1. The larger the reference electrode voltage of the controllable precision voltage stabilizing source Z1, the smaller the negative electrode voltage; the smaller the reference electrode voltage of the controllable precision voltage stabilizing source Z1, the larger the negative electrode voltage. Therefore, the larger the output voltage VOUT, the smaller the negative electrode voltage of the controllable precision voltage stabilizing source Z1, the lower the conduction degree of the third MOS tube V3, and the output voltage VOUT decreases; the smaller the output voltage VOUT, the larger the negative electrode voltage of the controllable precision voltage stabilizing source Z1, the higher the conduction degree of the third MOS tube V3, and the output voltage VOUT increases; thereby achieving voltage stabilization output.

[0067] In another embodiment, the third capacitor C3 can be omitted. The third capacitor C3 is used to avoid sudden voltage fluctuation at the controllable precision voltage regulator Z1 when adjusting the first potentiometer RP1.

[0068] The working principle of the present invention is: the power processing module is used to introduce a DC power supply VCC and supply power to a voltage stabilizing output module through a first switch tube; the fluctuation regulation module is used to adjust the conduction state of the first switch tube based on the size of the DC power supply VCC to realize the integration of a soft start protection circuit and an overvoltage protection circuit; the voltage stabilizing output module is used to output a stable voltage through a second switch tube to supply electrical equipment.

[0069] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered as exemplary and non-restrictive in all respects.

[0070] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
