In this embodiment, there is provided a control method of a server power supply system operating on the mobile terminal, where the server power supply system includes a boost energy storage circuit and a DC-DC converter electrically connected to the boost energy storage circuit, and fig. 2 is a flowchart of a control method of the server power supply system according to an embodiment of the present application, as shown in fig. 2, and the flowchart includes the following steps:
step S202, determining whether an input signal of the DC-DC converter is in a first signal range, and controlling the boost tank circuit to operate when the input signal of the DC-DC converter is in the first signal range;
Specifically, at the time of system power-up, initialization starts, and a first signal range is set. The DC-DC converter is a direct current-direct current converter, which is a circuit for converting electric energy or an electromechanical device, and can convert a direct current power supply into a direct current (or approximately direct current) power supply with different voltages. Its power can range from very small (small battery) to very large (high voltage power supply conversion). Some dc-dc converters have the same reference point for their output voltage and input voltage, while some dc-dc converters have their output voltage isolated from the input voltage. The DC-DC converter is used to convert a high voltage input signal to a server power system into a low voltage output signal, for example 12V or 54V. The boost tank circuit mainly comprises: the power supply comprises a direct current power supply, an energy storage inductor, a switching tube, a Schottky diode, an energy storage capacitor and a load. The boost tank circuit is used for providing a power-down maintaining function for the server power supply. The controller of the server power system samples the input signal of the DC-DC converter at fixed time intervals and determines whether the input signal of the DC-DC converter is in a first signal range, and if the input signal of the DC-DC converter is in the first signal range, the boost tank circuit may be enabled.

Specifically, a second signal range is set, the controller of the server power supply system samples the output signal of the boost tank circuit at fixed time intervals, and determines whether the output signal of the boost tank circuit is in the second signal range, and the DC-DC converter is enabled when the output signal of the boost tank circuit is in the second signal range.
Through the steps, the electric signals of some nodes of the server power supply system are detected and judged, such as the input signals of the DC-DC converter and the output signals of the boost energy storage circuit. Through the judgment of the value range, whether the DC-DC converter and the boost energy storage circuit in the server power supply system are in a normal state or not can be determined, and under the condition that all conditions are met and the normal state is determined, all links of the server power supply system are controlled, so that the boost energy storage circuit and the DC-DC converter work in sequence. The method can increase the reliability of the power on of the server power supply, so that the server power supply can enter a steady state operation stage more stably.
The main body of execution of the above steps may be a terminal, but is not limited thereto.
In an exemplary embodiment, the step 204 further includes: step S206, determining whether the output signal of the DC-DC converter is in a third signal range, and determining that the power-on of the server power system is successful when the output signal of the DC-DC converter is in the third signal range.
Specifically, the third signal range is set, the controller of the server power system samples the output signal of the DC-DC converter at fixed time intervals, and determines whether the output signal of the DC-DC converter is in the third signal range, and if the output signal of the DC-DC converter is in the third signal range, it may be determined that the server power system is successfully started.
In an exemplary embodiment, the step S204 may be implemented in other manners, for example: step S2042, determining whether the output signal of the boost tank circuit is within the second signal range; step S2044 of determining whether the temperature of the DC-DC converter is within a first temperature range; step S2046, controlling the DC-DC converter to operate when the output signal of the boost tank circuit is in the second signal range and the temperature of the DC-DC converter is in the first temperature range.
Specifically, in addition to the above signal range determination, the temperature of the server power supply may also be determined. The controller of the server power system may sample the temperature of the DC-DC converter using a thermistor or a temperature sampling chip and determine whether the temperature of the DC-DC converter is in a first temperature range, and may enable the DC-DC converter when the output signal of the boost tank circuit is in the second signal range and the temperature of the DC-DC converter is in the first temperature range.
In an exemplary embodiment, after including the above steps S2042 to S2046, further includes: and step S2048, outputting a first fault signal and controlling the DC-DC converter to stop working when the temperature of the DC-DC converter is greater than the maximum value of the first temperature range, wherein the first fault signal is used for representing that the DC-DC converter breaks down.
Specifically, the controller of the server power system may sample the temperature of the DC-DC converter using a thermistor or a temperature sampling chip, determine whether the temperature of the DC-DC converter is in a first temperature range, report an over-temperature fault of the DC-DC converter when the temperature of the DC-DC converter is not in the first temperature range, and turn off an enable signal of the DC-DC converter.
In an exemplary embodiment, after step S202, step S201 is further included to control the operation of the hot plug circuit.
In particular, hot plug-and-hot plug refers to that a module and a board card are inserted into or pulled out of a system without influencing the normal operation of the system under the condition that a system power supply is not closed, so that the reliability, the quick maintainability, the redundancy, the timely recovery capability to disasters and the like of the system can be improved. For a high-power modularized power system, the hot plug technology can replace a power module with a fault under the condition of maintaining the voltage of the whole power system, and ensure that other power modules in the modularized power system normally operate. The hot plug circuit is used for preventing the problem of overcurrent peak of input current when the server power supply is plugged in and plugged out, and enables the hot plug circuit under the condition that the input signal of the DC-DC converter is in the first signal range.
In an exemplary embodiment, the step S201 further includes outputting a second fault signal if the input signal of the DC-DC converter is not in the first signal range, where the second fault signal is used to indicate that the hot plug circuit of the server power system fails.
Specifically, when the input signal of the DC-DC converter is lower than the first signal range or higher than the first signal range, a fault is reported to the hot plug circuit.
In an exemplary embodiment, on the basis of the step S202 and the step S204, the method further includes a step S203, outputting a third fault signal when the output signal of the boost tank circuit is not in the second signal range, and controlling the boost tank circuit to stop working, where the third fault signal is used to indicate that the boost tank circuit fails; and step S205, outputting a fourth fault signal and controlling the DC-DC converter to stop working when the output signal of the DC-DC converter is not in the first signal range, wherein the fourth fault signal is used for representing that the DC-DC converter fails.
Specifically, the controller of the server power supply system samples the output signal of the boost energy storage circuit at fixed time intervals, compares the output signal with the normal signal range set by initialization, and judges that if the sampled signal is higher than the preset signal range or lower than the preset signal range, the controller reports the fault of the boost energy storage circuit and closes the enabling signal of the boost energy storage circuit.
In an exemplary embodiment, in addition to the step S202 and the step S204, a step S207 is further included, and in the case of determining whether the input signal of the DC-DC converter is in the first signal range, the unidirectional conductive circuit of the server power supply system is controlled to stop operating.
Specifically, the Oring circuit is a single-phase conductive circuit and is mainly used for ensuring that the single power supplies are mutually independent and no reverse filling phenomenon occurs. The unidirectional conductive circuit is used for preventing the load end of the server from influencing the power supply, and can be an MOS tube. When judging the input signal of the DC-DC converter, the unidirectional conducting circuit is closed, so that the influence of the starting-up process of the server power supply system on the subsequent server is prevented.
In an exemplary embodiment, the above step S206 may also be implemented by: and controlling the unidirectional conductive circuit to work.
Specifically, in the case where the output signal of the above-described DC-DC converter is in the above-described third signal range, the unidirectional conductive circuit is further enabled.
In order to enable those skilled in the art to more clearly understand the technical solutions of the present application, the implementation procedure of the peak-to-valley period determining method of the novel power system of the present application will be described in detail below with reference to specific embodiments.

specifically, at the time of system power-up, initialization starts, and a first signal range is set. The DC-DC converter is a direct current-direct current converter, which is a circuit for converting electric energy or an electromechanical device, and can convert a direct current power supply into a direct current (or approximately direct current) power supply with different voltages. Its power can range from very small (small battery) to very large (high voltage power supply conversion). Some dc-dc converters have the same reference point for their output voltage and input voltage, while some dc-dc converters have their output voltage isolated from the input voltage. The DC-DC converter is used to convert a high voltage input signal to a server power system into a low voltage output signal, for example 12V or 54V. The boost tank circuit mainly comprises: the power supply comprises a direct current power supply, an energy storage inductor, a switching tube, a Schottky diode, an energy storage capacitor and a load. The boost tank circuit is used for providing a power-down maintaining function for the server power supply. The controller of the server power system samples the input signal of the DC-DC converter at fixed time intervals and determines whether the input signal of the DC-DC converter is in a first signal range, and if the input signal of the DC-DC converter is in the first signal range, the boost tank circuit may be enabled.

Specifically, a second signal range is set, the controller of the server power supply system samples the output signal of the boost tank circuit at fixed time intervals, and determines whether the output signal of the boost tank circuit is in the second signal range, and the DC-DC converter is enabled when the output signal of the boost tank circuit is in the second signal range.
By the device, the electric signals of some nodes of the server power supply system are detected and judged, such as the input signals of a DC-DC converter and the output signals of a boost energy storage circuit. Through the judgment of the value range, whether the DC-DC converter and the boost energy storage circuit in the server power supply system are in a normal state or not can be determined, and under the condition that all conditions are met and the normal state is determined, all links of the server power supply system are controlled, so that the boost energy storage circuit and the DC-DC converter work in sequence. The device can increase the reliability of the power on of the server power supply, so that the server power supply can enter a steady state operation stage more stably.
In an exemplary embodiment, the second determining module further includes: and the third determining module is used for determining whether the output signal of the DC-DC converter is in a third signal range or not, and determining that the power-on of the server power supply system is successful when the output signal of the DC-DC converter is in the third signal range.

Specifically, in addition to the above signal range determination, the temperature of the server power supply may also be determined. The controller of the server power system may sample the temperature of the DC-DC converter using a thermistor or a temperature sampling chip and determine whether the temperature of the DC-DC converter is in a first temperature range, and may enable the DC-DC converter when the output signal of the boost tank circuit is in the second signal range and the temperature of the DC-DC converter is in the first temperature range.
In one exemplary embodiment, on the basis of including the first determination submodule, the second determination submodule, and the third determination submodule, further including: the output submodule is used for outputting a first fault signal and controlling the DC-DC converter to stop working under the condition that the temperature of the DC-DC converter is larger than the maximum value of the first temperature range, wherein the first fault signal is used for representing that the DC-DC converter breaks down.
Specifically, the controller of the server power system may sample the temperature of the DC-DC converter using a thermistor or a temperature sampling chip, determine whether the temperature of the DC-DC converter is in a first temperature range, report an over-temperature fault of the DC-DC converter when the temperature of the DC-DC converter is not in the first temperature range, and turn off an enable signal of the DC-DC converter.

For a high-power modularized power system, the hot plug technology can replace a power module with a fault under the condition of maintaining the voltage of the whole power system, and ensure that other power modules in the modularized power system normally operate.

Specifically, the controller of the server power supply system samples the output signal of the boost energy storage circuit at fixed time intervals, compares the output signal with the normal signal range set by initialization, and judges that if the sampled signal is higher than the preset signal range or lower than the preset signal range, the controller reports the fault of the boost energy storage circuit and closes the enabling signal of the boost energy storage circuit.

Specifically, the Oring circuit is a single-phase conductive circuit and is mainly used for ensuring that the single power supplies are mutually independent and no reverse filling phenomenon occurs. The unidirectional conductive circuit is used for preventing the load end of the server from influencing the power supply, and can be an MOS tube. When judging the input signal of the DC-DC converter, the unidirectional conducting circuit is closed, so that the influence of the starting-up process of the server power supply system on the subsequent server is prevented.
