Description

Technical Field

[0001] This utility model relates to the field of voltage conversion, and in particular to a drive circuit, electronic device and mobile platform. Background Technology

[0002] With the continuous development of technology, many electronic devices require boost circuit modules to achieve high-voltage output and realize corresponding functions. Boost circuit modules can convert the power supply voltage into a higher voltage for output, among which the most commonly used is the open-loop boost circuit module. In existing solutions, an open-loop boost circuit module, in conjunction with a switch connected in parallel across the output capacitor of the open-loop boost circuit module, can supply the load with the output voltage.

[0003] However, in existing solutions, to ensure that the output voltage (i.e., the voltage of the output capacitor) across the load remains consistent, after the load operates once, to allow the load to operate again, the energy of the output capacitor needs to be discharged by closing a switch (so that the voltage of the output capacitor drops to zero), and then the output capacitor is recharged based on the open-loop boost circuit module, so that the output voltage returns to the previous level. This results in a considerable amount of energy being wasted in the output capacitor, leading to low drive efficiency. Utility Model Content

[0037] The present application will be further described in detail below with reference to the accompanying drawings.

[0038] This invention provides a driving circuit, electronic device, and mobile platform for improving driving efficiency.

[0039] Many existing electronic devices require boost circuit modules to achieve high-voltage output. This is also true for the lasers in LiDAR systems. Current solutions utilize open-loop boost circuit modules as the boost circuit, along with a switch connected in parallel across the output capacitor in the open-loop boost circuit module to supply the output voltage. However, in existing solutions, to ensure a consistent output voltage across the load (i.e., the voltage across the output capacitor), after each load operation, the switch needs to be closed to discharge the energy from the output capacitor (causing the voltage to drop to zero) before the load can operate again. Then, the output capacitor is recharged using the open-loop boost circuit module, returning the output voltage to the previous level. This results in a significant amount of energy being wasted in the output capacitor, leading to low drive efficiency. Furthermore, since at least two switches are involved, timing control is complex. Under these inefficient conditions, the temperature of the electronic device rises rapidly, reducing its reliability. To address the aforementioned issues, this application provides a drive circuit, electronic device, and mobile platform that ensures a consistent output voltage for each load, prevents energy leakage to ground, requires only the switch in the boost circuit module without additional switches, simplifies timing control, increases efficiency, and slows down the temperature rise of the electronic device, thereby improving its reliability.

[0042] The following describes a driving circuit according to this application. Please refer to... Figure 1 One embodiment of the driving circuit of this application includes: a first power supply, a boost circuit module, a unidirectional conduction module, and a reference voltage supply module;

[0043] Both the boost circuit module and the unidirectional conduction module have input and output terminals. The reference voltage supply module has a reference voltage signal terminal and a ground terminal. The negative terminal of the first power supply and the ground terminal of the reference voltage supply module are both grounded. The positive terminal of the first power supply is connected to the input terminal of the boost circuit module. The output terminal of the boost circuit module is connected to the output terminal of the unidirectional conduction module. The input terminal of the unidirectional conduction module is connected to the reference voltage signal terminal of the reference voltage supply module. The output terminal of the boost circuit module is used to connect to the load.

The unidirectional conduction module only conducts in a fixed direction under certain conditions.

[0044] The working principle of this embodiment will now be explained. The first power supply provides the input voltage, and the boost circuit module performs boost conversion, converting the input voltage into the output voltage. If the output voltage is lower than the reference voltage, the unidirectional conduction module is turned on, and the output voltage is pulled up and stabilized to the reference voltage. If the output voltage is higher than the reference voltage, the unidirectional conduction module is turned off, and the output voltage is supplied to the load to enable the load to work.

[0045] In this invention, the drive circuit includes a boost circuit module, a unidirectional conduction module, and a reference voltage supply module. The output terminal of the boost circuit module is connected to the load, providing an output voltage to the load. When the load is working, the output voltage continuously decreases. When the voltage drops significantly below the reference voltage provided by the reference voltage supply module, the unidirectional conduction module conducts, limiting the output voltage to near the reference voltage (i.e., the lower limit of the output voltage is always pulled to near the reference voltage). Since the energy that the boost circuit module can provide each time is fixed, the sum of the energy provided by the boost circuit module and the fixed lower limit of the output voltage is essentially fixed. No energy is discharged to ground, resulting in high drive efficiency and improved energy utilization.

The output terminal of the boost circuit module is used to connect to the load.

Specifically, the DC-DC conversion unit can be a boost unit, such as a boost unit, or a buck unit, such as a buck unit, etc., which can be set according to actual needs, and is not limited here.

[0050] In the second implementation, please refer to Figure 4 The reference voltage supply module includes: a low dropout linear stabilizing unit (i.e., an LDO unit), an input capacitor, an output capacitor, and a third power supply;

[0051] The low-dropout linear stabilizing unit is provided with an input terminal and an output terminal. The input terminal of the low-dropout linear stabilizing unit is connected to the positive terminal of the third power supply. The output terminal of the low-dropout linear stabilizing unit serves as the reference voltage signal terminal. The negative terminal of the third power supply serves as the ground terminal. One end of the input capacitor is connected to the input terminal of the low-dropout linear stabilizing unit, and the other end of the input capacitor is grounded. One end of the output capacitor is connected to the output terminal of the low-dropout linear stabilizing unit, and the other end of the output capacitor is grounded.

[0052] The boost circuit module includes: an inductor L, a switching unit, a second diode D2, and an energy storage capacitor C;

[0053] One end of the inductor L serves as the input terminal of the boost circuit module. The other end of the inductor L is connected to one end of the switching unit and the anode of the second diode D2, respectively. The other end of the switching unit is grounded. The cathode of the second diode D2 is connected to one end of the energy storage capacitor C, and the other end of the energy storage capacitor C is grounded. The cathode of the second diode D2 serves as the output terminal of the boost circuit module. Specifically, the inductor L stores energy and releases it to the energy storage capacitor C, which in turn provides the output voltage to the load.

[0054] The switching unit can have multiple implementations, as long as it can realize the switching of the corresponding branch to achieve voltage boosting. No specific limitation is made here; three implementations are described below. In the first implementation, the switching unit includes: a short-circuit switch S1;

[0055] One end of the short-circuit switch S1 is connected to the anode of the second diode D2, and the other end of the short-circuit switch S1 is grounded.

[0056] In the second embodiment, the switching unit includes: an NMOS transistor and a controller;

[0060] For ease of understanding, this embodiment will be described using the first implementation method.

[0061] Furthermore, to ensure the stability and reliability of the drive circuit operation, please refer to the following for details. Figure 5 The driving circuit further includes: a power supply capacitor and a supply capacitor;

[0062] One end of the power supply capacitor is connected to the positive terminal of the first power supply E, and the other end of the power supply capacitor is grounded. The power supply capacitor can stabilize the input voltage and prevent fluctuations in the input voltage from affecting the normal operation of the load.

[0063] One end of the supply capacitor is connected to the reference voltage signal terminal of the reference voltage supply module, and the other end of the supply capacitor is grounded. The supply capacitor can stabilize the output voltage and prevent fluctuations in the output voltage from affecting the normal operation of the load.

[0064] The working principle of this embodiment will now be illustrated with an example. When the drive circuit is turned on, the first power supply E provides the input voltage. The boost circuit module converts the input voltage into an output voltage and outputs it to the load. During each output, the voltage of the energy storage capacitor C (i.e., the output voltage) gradually decreases. When the output voltage decreases and causes the first diode D1 to conduct, the reference voltage supply module provides energy, keeping the voltage of the energy storage capacitor C near the reference voltage. At this time, the next boost is performed, controlling the short-circuit switch S1 to close. The first power supply E enables the inductor L to store energy. After a period of time, the short-circuit switch S1 opens, and the energy from the first power supply E and the inductor L is transferred to the energy storage capacitor C. The output voltage of the energy storage capacitor C increases, exceeding the reference voltage. The first diode D1 turns off, and the output voltage is supplied to the load, enabling the load to operate. The energy corresponding to the output voltage is always the sum of the energy corresponding to the reference voltage, the energy provided by the first power supply E during the period when the short-circuit switch S1 is open, and the energy stored in the inductor L, and so on.

[0065] In this embodiment, the drive circuit includes a boost circuit module, a unidirectional conduction module, and a reference voltage supply module. The output of the boost circuit module is connected to the load, providing an output voltage to the load. When the load is working, the output voltage continuously decreases. When the voltage drops significantly below the reference voltage provided by the reference voltage supply module, the unidirectional conduction module conducts, limiting the output voltage to near the reference voltage (i.e., the lower limit of the output voltage is always pulled to near the reference voltage). Since the energy that the boost circuit module can provide each time is fixed, the sum of the energy provided by the boost circuit module and the fixed lower limit of the output voltage is essentially fixed. No energy is discharged to ground, resulting in high drive efficiency, slow temperature rise of the electronic device, and improved energy utilization. In addition, the drive circuit has only one short-circuit switch S1, making timing control simple and reliable.

[0066] The above describes a driving circuit according to this utility model. The following describes an electronic device according to this utility model. Please refer to... Figure 6 An embodiment of an electronic device according to the present invention includes the aforementioned driving circuit, the driving circuit including a boost circuit module, the boost circuit module being provided with an output terminal, and the device further including: a load;

[0067] The load is connected to the output terminal of the boost circuit module.

[0068] The working principle of this embodiment will now be illustrated with an example. The driving circuit provides a suitable output voltage to the load through the output terminal, and the load operates normally based on the output voltage.

[0069] In this invention, the driving circuit includes a first power supply E, a boost circuit module, a unidirectional conduction module, and a reference voltage supply module. The first power supply E provides the input voltage. The boost circuit module converts the input voltage into an output voltage and supplies it to the load. When the output voltage is too low, the unidirectional conduction module conducts to raise the output voltage to the reference voltage. When the output voltage is high, it is supplied to the load, enabling the load to operate. This provides a suitable output voltage to the load, ensuring its normal operation and improving the stability and reliability of the electronic equipment.

[0070] The following is a detailed description of an electronic device according to this utility model. Please refer to... Figure 7 Another embodiment of the electronic device of the present invention includes the aforementioned driving circuit, the driving circuit including a boost circuit module, the boost circuit module being provided with an output terminal, and the device further including: a load;

[0071] The load is connected to the output terminal of the boost circuit module.

[0072] The load includes: a laser and a laser emission switch;

[0073] The laser has an input terminal and an output terminal. The input terminal of the laser is connected to the output terminal of the boost circuit module, and the output terminal of the laser is grounded through the laser emission switch.

[0074] The working principle of this embodiment will now be illustrated with an example. The first power supply E provides the input voltage, closing the short-circuit switch S1 to store energy in the inductor L. After a period of time, the short-circuit switch S1 is opened, and the energy from the first power supply E and the inductor L is supplied to the energy storage capacitor C, causing the output voltage to rise above the reference voltage. The first diode D1 turns off, and then the switch in the load is closed, allowing the laser to operate. As the load consumes energy, the output voltage decreases. When the output voltage falls below the reference voltage, the first diode D1 turns on, stabilizing the output voltage near the reference voltage. Then, the short-circuit switch S1 is closed again to store energy in the inductor L, and this process continues in sequence.

[0075] In this embodiment, the drive circuit includes a boost circuit module, a unidirectional conduction module, and a reference voltage supply module. The output of the boost circuit module is connected to the load, providing an output voltage to the load. When the load is working, the output voltage continuously decreases. When the voltage drops significantly below the reference voltage provided by the reference voltage supply module, the unidirectional conduction module conducts, limiting the output voltage to near the reference voltage (i.e., the lower limit of the output voltage is always pulled to near the reference voltage). Since the energy that the boost circuit module can provide each time is fixed, the sum of the energy provided by the boost circuit module and the fixed lower limit of the output voltage is essentially fixed. No energy is discharged to ground, resulting in high drive efficiency, slow temperature rise of the electronic device, and improved energy utilization. In addition, the drive circuit has only one short-circuit switch S, making timing control simple and reliable.
