[0050] Refer to the following Figures 1 to 5 A power supply device output control method, electronic device, power supply device and apparatus according to an embodiment of the present application are described.

[0051] The present application embodiment provides a power supply device output control method, which is applied to the MCU300 of the power supply device, such as Figure 1 to Figure 2 As shown, the method includes:

[0052] Step S100: Generate a one-way linked list;

[0053] Step S200: inserting multiple nodes into the one-way linked list in sequence, the multiple nodes corresponding to multiple working steps of the power supply device, the waveform types output by the multiple working steps are different, each node includes a pointer, a waveform parameter corresponding to the working step and a preset waveform running time corresponding to the working step, and the pointer of each node is used to point to the address of the next node;

[0054] Step S300: outputting waveform signals according to the waveform parameters of multiple nodes and the preset waveform running time.

[0055] In the embodiment of the present application, the waveform of the corresponding step can be fitted according to the waveform parameters of the node and the preset waveform running time, without storing the step description data of each data point information of multiple waveforms. The waveform parameters and preset waveform running time of multiple nodes in the one-way linked list are read in sequence, and multiple waveforms of multiple steps can be fitted and output in sequence.

[0056] In the above step S200, the preset waveform running time indicates the output duration of the waveform corresponding to the node. The waveform parameters of the node can be determined according to the waveform output by the corresponding step, for example, the waveform parameters include waveform type, amplitude, offset, phase angle and frequency, etc. According to the waveform parameters, the waveform can be fitted by the algorithm to obtain the output waveform signal, and then the waveform signal is continuously output based on the preset waveform running time.

[0057] In some embodiments of the present application, the waveform types include sine wave, triangle wave, pulse wave and arbitrary waveform. When the waveform output by the process step is a sine wave, the waveform parameters include waveform type, amplitude, offset, phase angle and frequency. When the waveform output by the process step is a triangle wave and a pulse wave, the waveform parameters include waveform type, amplitude, offset, phase angle, frequency and duty cycle.

[0058] Some implementation methods of the present application, such as Figure 5 As shown, the MCU300 of the power supply device is connected to a Field Programmable Gate Array (FPGA), and the FPGA310 is connected to multiple output channels 330. The MAC is connected to the SDRAM320. The MCU300 is used to execute the power supply device output control method. The SDRAM320 is used to expand the RAM, provide cache, and cache data. The FPGA310 is responsible for forwarding the communication data between the MCU300 and the output channel 330, and synchronously forwards the voltage value or current value configured by the MCU300 to the multiple output channels 330 after receiving it, and performs output synchronization control between the output channels 330 at the same time. After receiving the voltage value or current value, the output channel 330 actually outputs and outputs a waveform signal.

[0059] In one embodiment of the present application, the step S300 of “outputting waveform signals according to waveform parameters of multiple nodes and preset waveform running time in sequence” is further described. The step S300 includes:

[0060] Step S310: acquiring the real-time waveform operation time of the power supply device according to a preset time interval;

[0061] Step S320: Starting from the first node of the one-way linked list, using the real-time waveform running time as the running reference time, executing a search strategy on the node to confirm the target node, the search strategy includes: obtaining the preset waveform running time of the node; comparing the running reference time with the preset waveform running time of the node, if the running reference time is less than the preset waveform running time of the node, confirming the node as the target node;

[0062] Step S330: Output a waveform signal according to the waveform parameters of the target node and the running reference time.

[0063] In this embodiment, the real-time waveform running time of the power supply device is obtained once every preset time interval, and the real-time waveform running time indicates the cumulative time that the power supply device has continuously output the waveform signal. Since the one-way linked list can only read the data of each node in turn, and fit the waveform corresponding to each node in turn for output, based on the real-time waveform running time, by comparing the preset waveform running time of each node, it is possible to find which node the power supply device is outputting the waveform signal corresponding to, thereby determining the target node. The target node is the node that is outputting the waveform.

[0064] In some implementations of the present application, the search strategy further includes:

[0065] Step S321: if the running reference time is greater than or equal to the preset waveform running time of the node, subtract the preset waveform running time of the node from the running reference time to obtain a new running reference time;

[0066] Step S322: According to the new running reference time, the search strategy is executed on the next node of the node until the target node is confirmed.

[0067] In this embodiment, when the running reference time is greater than or equal to the preset waveform running time of the node, it indicates that the waveform of the current node has been outputted, so the running reference time is subtracted from the preset waveform running time of the node to obtain a new running reference time. The new running reference time is used to determine whether the waveform of the next node has been outputted, until the target node is found.

[0068] The running reference time corresponding to the target node actually indicates the length of time the waveform of the target node has been output. Based on the waveform parameters of the target node and the corresponding running reference time, the waveform point of the waveform signal currently output by the power supply device can be determined, and then the waveform signal of the target node can be fitted and output from this waveform point.

[0069] In some implementations of the present application, before "inserting multiple nodes into the one-way linked list in sequence" in step S200, the following steps are also included:

[0070] Step S210: inserting a head node into the one-way linked list, where the head node includes the number of loops;

[0071] The step S300 of “outputting waveform signals according to the waveform parameters of the plurality of nodes and the preset waveform running time in sequence” includes:

[0072] Step S310: Obtain the number of cycles;

[0073] Step S320: Based on the number of cycles, based on the number of cycles, the waveform signals are cyclically output according to the waveform parameters of the multiple nodes and the preset waveform running time.

[0074] In this embodiment, by inserting a head node in the one-way linked list and setting the number of loops of the head node, the number of operations of the one-way linked list is set. For example, if the number of loops in the head node is 3, the one-way linked list is read three times in a loop, and the waveform signals of multiple nodes in the one-way linked list are output three times in a loop.

[0075] In some implementation modes of the present application, the head node also includes the number of nodes in the one-way linked list and output attributes, and the output attributes are used to indicate whether the output waveform is a voltage or a current.

[0076] In one embodiment of the present application, when there is a target step among the multiple steps, the target step is a step of outputting an arbitrary waveform, and the method further includes:

[0077] Step S400: Setting a data buffer in SDRAM 320;

[0078] Step S500: obtaining information of multiple data points of an arbitrary waveform;

[0079] Step S600: storing information of a plurality of data points into a data buffer;

[0080] The waveform parameters of the node corresponding to the target process step also include the address information of the data point information in the data buffer.

[0081] In this embodiment, since the arbitrary waveform cannot be fitted by an algorithm, it is necessary to store multiple data point information of the arbitrary waveform in the data buffer. When the node corresponding to the target step is the target node, by running the reference time and frequency, it is possible to determine which data point of the arbitrary waveform is output, find its address information in the data buffer, find the data point signal of the corresponding address according to the address information, and output the waveform signal according to the data point signal.
