Description

Technical Field

[0001] This utility model relates to the field of DC-DC converter technology, and specifically to a fast response device for a step-down DC-DC converter. Background Technology

[0002] A DC-DC converter, also known as a direct current converter, uses a controllable switch (such as a MOSFET) to perform high-frequency switching, storing the input electrical energy in a capacitor (inductor). When the switch is turned off, the electrical energy is released to the load to provide power. Its output power or voltage capability is related to the duty cycle (the ratio of the switch's on time to the entire switching cycle). Switching power supplies can be used for boost and buck converters.

[0003] Currently, DC-DC converters lack voltage regulation and power input processing structures, thus failing to improve their response speed. Therefore, a fast response device for a buck DC-DC converter is proposed. This device processes the input voltage through a voltage regulator, a power transmission module, and a metal-oxide-semiconductor field-effect transistor, enabling the current to enter the DC-DC converter body stably and quickly, thereby improving the DC-DC converter's response speed. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a fast response device for a step-down DC-DC converter. By processing the input voltage through a voltage regulator, a power transmission module, and a metal-oxide-semiconductor field-effect transistor, the current can enter the DC-DC converter body stably and quickly, which helps to improve the response speed of the DC-DC converter.

[0005] The technical solution adopted by this utility model to solve its technical problem is a fast response device for a step-down DC-DC converter, including a DC-DC converter body, a power input component, a ventilation component and a ventilation box. The ventilation component is disposed on the top of the DC-DC converter body, and the power input component is disposed on the top of the DC-DC converter body located at one end of the ventilation component. The power input component includes a protective box body that is fixed to the top of the DC-DC converter body by bolts. Inside the protective housing, a voltage regulator is installed via a mounting bracket. A circuit board is fixed to the top of the voltage regulator with bolts. A power transmission module is soldered to the top of the circuit board. A metal-oxide-semiconductor field-effect transistor is soldered to the top of the circuit board on one side of the power transmission module. A digital voltmeter is embedded in the top of the protective housing.

[0006] By adopting the above technical solution, the voltage regulator performs voltage regulation on the incoming current, and then the current is controlled by the power transmission module to be delivered to the DC-DC converter body through the metal oxide semiconductor field-effect transistor. The digital display voltmeter can display the incoming voltage.

[0007] Specifically, the ventilation assembly includes a ventilation box that is bolted to the top of the DC-DC converter body, and cooling fans are mounted on both ends of the ventilation box via mounting brackets.

[0008] Specifically, through holes are provided at equal intervals between the ventilation box and the DC-DC converter body, and a dustproof mesh is fixed inside the ventilation box located on top of the cooling fan by bolts.

[0009] Specifically, a connector is embedded on one side of the protective box.

[0010] Specifically, both the protective box and the ventilation box are made of fiberglass material.

[0011] The beneficial effects of this utility model are: The present invention discloses a fast response device for a step-down DC-DC converter. The external current is processed and stabilized by a voltage regulator before being transmitted to the power transmission module. The power transmission module controls the current to be delivered to the DC-DC converter body via a metal-oxide-semiconductor field-effect transistor. The metal-oxide-semiconductor field-effect transistor has a fast switching speed and low loss, which helps to improve the response speed of the DC-DC converter body.

[0012] The present invention discloses a fast response device for a step-down DC-DC converter. The cooling fan draws external air into the ventilation box through a dust filter and blows it into the DC-DC converter body through multiple through holes. This can dissipate heat from the DC-DC converter body, prevent it from being in a high-temperature state, and prevent the response speed from being affected by high temperature.

Figure 1-4 As shown, the present invention provides a fast response device for a step-down DC-DC converter, comprising a DC-DC converter body 1, a power input component 2, a ventilation component 3, and a ventilation box 301. The ventilation component 3 is disposed on the top of the DC-DC converter body 1, and the power input component 2 is disposed on the top of the DC-DC converter body 1 at one end of the ventilation component 3. The power input component 2 includes a protective box 201 fixed to the top of the DC-DC converter body 1 by bolts. Inside the protective housing 201, a voltage regulator 202 is installed via a mounting bracket. A circuit board 203 is fixed to the top of the voltage regulator 202 by bolts. A power transmission module 204 is soldered to the top of the circuit board 203. A metal oxide semiconductor field-effect transistor 205 is soldered to the top of the circuit board 203 on one side of the power transmission module 204. A digital display voltmeter 206 is embedded in the top of the protective housing 201.

[0017] In use, the voltage regulator 202 regulates the voltage of the incoming current, and then the power transmission module 204 controls the current to be delivered to the DC-DC converter body 1 through the metal oxide semiconductor field effect transistor 205. The digital display voltmeter 206 can display the incoming voltage.

[0018] For example, such as Figure 3 As shown, the present invention also includes a ventilation assembly 3 comprising a ventilation box 301 fixed to the top of the DC-DC converter body 1 by bolts, wherein cooling fans 302 are mounted on both ends of the ventilation box 301 by mounting brackets.

[0019] When in use, the cooling fan 302 operates to dissipate heat from the DC-DC converter body 1.

[0020] For example, such as Figure 3 As shown, the present invention also includes a through hole 303 that is equidistantly provided between the ventilation box 301 and the DC-DC converter body 1, and a dustproof mesh 304 is fixed inside the ventilation box 301 located on the top of the cooling fan 302 by bolts.

[0021] When in use, the opening of the through hole 303 facilitates the blowing of the gas drawn into the ventilation box 301 into the DC-DC converter body 1, and the dustproof net 304 can prevent dust and other objects from entering the ventilation box 301.

[0022] For example, such as Figure 2 As shown, the present invention also includes a connector 207 embedded on one side of the protective box 201.

[0025] When in use, the protective box 201 and ventilation box 301, made of fiberglass material, have high strength, good insulation and corrosion resistance.

[0026] In use, the power supply is connected to connector 207. The external power supply is processed and stabilized in voltage regulator 202 and then transmitted to power transmission module 204. Power transmission module 204 controls the power supply to be transmitted to DC-DC converter body 1 via metal oxide semiconductor field-effect transistor 205. Metal oxide semiconductor field-effect transistor 205 has fast switching speed and low loss, which helps to improve the response speed of DC-DC converter body 1. Digital display voltmeter 206 can display the voltage of the current entering voltage regulator 202. Turning on the cooling fan 302 draws external air into the ventilation box 301 through the dust filter 304, and blows it into the DC-DC converter body 1 through multiple through holes 303. This can dissipate heat from the DC-DC converter body 1, prevent it from being in a high-temperature state, and prevent the response speed from being affected by high temperature.
