[0026] For the purpose of simplicity and illustration, the principles of the embodiments are mainly described by reference to examples. In the following description, many specific details are proposed to provide a thorough understanding of the embodiments. However, it is obvious that for those of ordinary skill in the art, these embodiments may not be limited to these specific details in practice. In some instances, known methods and structures are not described in detail to avoid making these embodiments unnecessarily difficult to understand. In addition, all embodiments can be used in combination with each other. Example

[0027] like Figure 1-2 As shown, this embodiment provides a circuit boosting method based on a voltage conversion chip, wherein the method is applied to a circuit boosting system based on a voltage conversion chip, and the method includes: S10, sending an instruction to connect an external power supply to a boost circuit including a voltage conversion chip, initializing the switch tube in the voltage conversion chip to a closed state, reading and recording initial state information of the inductor, capacitor and load in the circuit, wherein the initial state information of the inductor includes no energy storage, the initial state information of the capacitor includes its initial voltage value, and the load is in a state of waiting for power supply; S20, according to the preset conduction trigger condition, the controller sends a control instruction to the voltage conversion chip to turn on the switch tube, thereby establishing a current path from the positive electrode of the power supply through the sampling resistor, the inductor, the first and second pins of the voltage conversion chip to the negative electrode of the power supply; The preset conduction trigger condition includes but is not limited to at least one of the following: triggering based on time interval, that is, triggering the switch tube to turn on every fixed time period; triggering based on circuit status monitoring, triggering the switch tube to turn on when the voltage across the capacitor is monitored to be lower than the set threshold; triggering based on load demand signal, triggering the switch tube to turn on when a high power demand signal from the load is received.

[0028] S30, during the establishment of the current path, the controller continuously monitors and regulates the current passing through the inductor, and based on the electromagnetic induction characteristics of the inductor, causes the inductor to store energy; S40. During the energy storage process of the inductor, the controller calculates and controls the discharge current of the capacitor to the load according to Ohm's law based on the initial voltage value and capacitance value of the capacitor and the equivalent resistance of the load, so as to ensure that the load obtains continuous power supply.

[0029] The temperature during the charging process is monitored, and when the temperature exceeds the preset safety threshold, cooling measures are taken; cooling measures include reducing the charging current, activating the heat dissipation device, and other measures that can achieve cooling.

[0030] S50, according to the preset disconnection trigger condition, the controller sends an instruction to the voltage conversion chip to turn off the switch tube, triggering the inductor to generate self-induced electromotive force based on the characteristic that the current cannot change suddenly, so that the polarity of the electromotive force at both ends of the inductor is reversed, and it is connected in series with the power supply to build a new power supply path; The preset disconnection trigger conditions include but are not limited to at least one of the following: triggering based on time interval, that is, the switch tube automatically disconnects after being turned on for a predetermined time; triggering based on inductor energy storage status monitoring, when the energy stored in the inductor is monitored to reach a set upper limit value, the switch tube is triggered to disconnect; triggering based on load voltage feedback, when the voltage across the load is monitored to be higher than the preset safety upper limit value, the switch tube is triggered to disconnect.

[0031] S60. After the new power supply path is constructed, the controller monitors and regulates the power supply current to the load after the power supply and the inductor are connected in series, and at the same time monitors and controls the charging process of the capacitor so that the voltage across its two ends gradually increases.

[0032] Furthermore, the switch tube is repeatedly turned on and off according to the preset operating frequency; in each cycle, the on time, off time and operating frequency of the switch tube are dynamically optimized and adjusted according to the time constant of the load and the real-time operating status, so as to achieve precise control of the boost effect and DC output stability.

[0033] Furthermore, during the cyclic operation, the controller continuously monitors the voltage across the load, compares it with the preset stable voltage range, and uses a filtering algorithm or feedback adjustment mechanism to smooth the voltage fluctuations in real time, ensuring that the load obtains a continuous and stable DC voltage supply on a macro level to meet its normal working requirements.

[0034] When the switch tube in the voltage conversion chip is turned on, the power supply is grounded through the sampling resistor, inductor, and one and two pins of the voltage conversion chip. At this time, the inductor begins to store energy, and the capacitor provides energy to the load.

[0035] When the switch is turned off, the power supply and inductor provide energy to the load and capacitor at the same time. During the energy release period, the polarity of the electromotive force at both ends of the inductor is the same as that of the power supply, which is equivalent to two power supplies in series, so the voltage obtained on the load is higher than the power supply voltage. The frequency of the switch on and off is called the operating frequency of the chip. As long as this frequency is high enough relative to the time constant of the load, a continuous DC voltage can be obtained on the load.

[0036] During the establishment of the current path, the controller of the present application continuously monitors and regulates the current passing through the inductor, and based on the electromagnetic induction characteristics of the inductor, causes the inductor to store energy; during the energy storage process of the inductor, the controller calculates and controls the discharge current of the capacitor to the load according to Ohm's law based on the initial voltage value, capacitance value and equivalent resistance of the capacitor, thereby ensuring that the load obtains a continuous supply of electrical energy, thereby achieving the technical effect of a small size and being applicable to a variety of application scenarios, and solving the technical problem that the traditional boost method is large in size and cannot be applied to a variety of application scenarios.
