Description

Technical Field

[0001] This utility model relates to a dynamic voltage regulation power supply motherboard. Background Technology

[0002] The dynamic voltage regulation power supply motherboard is the core power supply unit of a computer hardware system. By adjusting the output voltage in real time to match the processor's load requirements, it directly affects system stability and energy efficiency. This technology involves key technical areas such as multiphase power supply topology, closed-loop feedback control, and power semiconductor drive, and is the energy management hub of modern high-performance computing equipment.

[0003] Traditional designs employ a fixed-phase voltage regulation mode, which results in high response delays during sudden load changes, leading to significant fluctuations in the processor's power supply voltage. Furthermore, the lack of a temperature compensation mechanism causes capacitor bank capacitance decay under high-temperature conditions, resulting in resonant point shifts and a surge in output ripple. More seriously, the coordination efficiency between the overload protection circuit and the voltage regulator is low, frequently triggering protective power-offs and causing data loss.

The filter capacitor is located at the right center of the top of the circuit board. The central processing unit slot is located at the right side of the top of the circuit board.

[0007] Based on the above technical solution, the dense component area includes a V-cut, an overload protection relay, a resistor, and a firmware storage chip.

It effectively suppresses voltage surges by adopting real-time current sampling and phase interleaving technology, and maintains a stable capacitance value of the filter capacitor bank through thermal coupling design.

Detailed Implementation

[0013] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0014] like Figure 1-3 As shown, a dynamic voltage regulation power supply motherboard includes a circuit board 1, a parallel port interface 2, a main power interface 3, a battery 4, a main control area 5, a dense component area 6, and surface mount capacitors 7. The parallel port interface 2 is located on the left side of the circuit board 1, the main power interface 3 is located on the left side of the front of the circuit board 1, the battery 4 is soldered to the front center of the top of the circuit board 1, the main control area 5 is located on the right side of the top of the circuit board 1, the dense component area 6 is located behind the center of the top of the circuit board 1, and multiple surface mount capacitors 7 are soldered to the right side of the front center of the top of the circuit board 1.

[0015] The main control area 5 includes field-effect transistors 8, dynamic voltage regulators 9, filter capacitors 10, and central processing unit slots 11. Multiple field-effect transistors 8 are soldered to the edge of the circuit board 1. The dynamic voltage regulators 9 are located at the rear right side of the top of the circuit board 1. The filter capacitors 10 are located at the right center of the top of the circuit board 1. The central processing unit slots 11 are located at the right side of the top of the circuit board 1.

[0016] The dense component area 6 includes a V-cut 12, an overload protection relay 13, a resistor 14, and a firmware storage chip 15. The V-cut 12 is located behind the top center of the circuit board 1. The overload protection relay 13 is soldered to the right side behind the top center of the circuit board 1. The resistor 14 is soldered to the top center of the circuit board 1. The firmware storage chip 15 is soldered to the left side of the top center of the circuit board 1.

[0017] The working principle of this utility model is as follows: When the central processing unit is inserted into the slot (11), the dynamic voltage regulator (9) collects the load current in real time through the resistor (14) and monitors the input status of the battery (4) and the main power interface (3) at the same time. Based on the algorithm model preset by the firmware storage chip (15), the controller drives the field effect transistor (8) group to output the pulse width modulation signal in a phase-interleaved manner. After being purified by the multi-level filter network composed of the chip capacitor (7) and the filter capacitor (10), it is sent to the processor. When an overcurrent is detected, the overload protection relay (13) quickly cuts off the power supply circuit. At this time, the low impedance path formed by the V-cut (12) layout quickly discharges the residual charge. The whole system achieves millisecond-level dynamic voltage regulation through the cooperation of the main control area (5) and the dense component area (6).

[0018] The above description is a preferred embodiment of the present utility model. For those skilled in the art, any changes, modifications, substitutions and variations made to the implementation methods without departing from the principles and spirit of the present utility model, based on the teachings of the present utility model, still fall within the protection scope of the present utility model.
