具体实施方式
本发明的核心是提供一种电源缓启动的控制方法、控制装置、控制设 备及存储介质，用于提高电源缓启动过程的稳定性，减小缓启动结束时的电压波动。
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
图1为本发明实施例提供的一种电源缓启动的控制方法的流程图。
如图1所示，本发明实施例提供的电源缓启动的控制方法包括：
S101：获取电压步进值和频率步进值。
本发明实施例提供的步骤基于电源控制器实现。
在本发明实施例中，电源缓启动的过程为电压步进与频率步进的过程。电源控制器接收工作人员输入的电压步进值和频率步进值以进行电压调节和频率调节。电压步进值和频率步进值均可以采用基准值，也可以针对不同型号的电源的缓启动过程通过仿真得到合适的值。
S102：利用电压步进值控制电压调节环路进行电压反馈调节，利用频率步进值控制频率调节环路进行频率反馈调节。
在具体实施中，按电压步进值更新电压调节环路的参考电压值(VrefSoft)，同步地，按频率步进值更新脉冲宽度调制(PWM)周期寄存器的参考频率值(PTPER)。
在缓启动开始前，电源处于关机状态，则在步骤S102之前还包括：
将电压调节环路的参考电压值设置为0，将脉冲宽度调制周期寄存器的参考频率值设置为最低值，以获得最大输出频率，将脉冲宽度调制模块处于失能状态。
利用电压步进值控制电压调节环路进行电压反馈调节，即对电压调节环路的参考电压值从0开始，按一定的速率增加电压步进值，得到新的参考电压值，则电压调节环路根据新的参考电压值进行电压调节。利用频率步进值控制频率调节环路进行频率反馈调节，即对频率调节环节的参考频 率值从最低值开始，与电压步进值的控制同步地增加频率步进值，得到新的参考频率值，则频率调节环路根据新的参考频率值进行频率调节。
当系统有开机指令时，开机标志位Onflag标志位会置1。当检测到开机标志位置为1后，系统进入开机状态，缓启动开始，此时利用电压步进值控制电压调节环路进行电压反馈调节，利用频率步进值控制频率调节环路进行频率反馈调节。
S103：获取电压调节环路的电压给定值和频率调节环路的频率给定值，按预设规则将频率给定值转换为第一给定值，并将电压给定值转换为与第一给定值同一计量单位的第二给定值。
S104：当第一给定值大于或等于第二给定值时，利用电压调节环路控制缓启动输出电压；当第二给定值大于第一给定值时，利用频率调节环路控制缓启动输出电压。
在步骤S102的执行过程中，需要选择电压调节环路和频率调节环路之一来控制缓启动输出电压。电压调节和频率调节相互制衡，才能保证电源缓启动过程的稳定性，则需要设置一种机制去衡量电压调节和频率调节之间的关系。
如步骤S103所述，按预设的采样频率分别对电压调节环路的电压给定值和频率调节环路的频率给定值进行采样后，按预设规则将频率给定值转换为第一给定值，并将电压给定值转换为与第一给定值同一计量单位的第二给定值，以便对电压调节和频率调节进行对比。
如步骤S104所述，当第一给定值大于或等于第二给定值时，说明频率调节速率过快，则采用电压调节环路控制缓启动输出电压。当第二给定值大于第一给定值时，说明电压调节速率过快，则采用频率调节环路控制缓启动输出电压。
S105：当检测到缓启动输出电压大于或等于预设缓启动电压时，确定缓启动完成。
检测缓启动输出电压，当缓启动输出电压大于或等于预设缓启动电压(如服务器电源通常为12V)时，确定缓启动完成。
本发明实施例提供的电源缓启动的控制方法，将频率调节加入电源缓 启动过程，利用电压步进值控制电压调节环路进行电压反馈调节，利用频率步进值控制频率调节环路进行频率反馈调节；在调节过程中，获取电压调节环路的电压给定值和频率调节环路的频率给定值，分别转换为同一计量单位的第二给定值和第一给定值，当第一给定值大于或等于第二给定值时，利用电压调节环路控制缓启动输出电压，当第二给定值大于第一给定值时，利用频率调节环路控制缓启动输出电压，使电压调节与频率调节相互制约。现有技术中在缓启动结束时，由于脉冲宽度调制频率从最起始频率开始计算，会导致缓启动结束的时刻出现电压波动的现象，影响缓启动过程的稳定性，而本发明实施例通过在缓启动过程中介入频率调节，有效提高了电源缓启动的稳定性，减小了缓启动完成时的电压波动。
在上述实施例的基础上，在本发明实施例中，电源缓启动的控制方法还包括：
根据缓启动的执行时长和目标缓启动时长调节频率步进值和电压步进值。
为满足电源缓启动的电压稳定性要求和缓启动时长要求，对于不同类型、不同型号的电源，根据缓启动的执行时长和目标缓启动时长调节频率步进值和电压步进值。
在具体实施中，可以在电源投入使用前进行仿真测试，在电源输出端接收输出电压波形，通过示波器查看缓启动过程中输出电压的变化情况，据此对频率步进值和电压步进值进行调整。
根据缓启动的执行时长对频率步进值和电压步进值进行调试，具体可以包括：
当频率调节环路的控制时长低于第一预设时长时，缩小频率步进值，否则增加频率步进值；当电压调节环路的控制时长低于第二预设时长时，缩小电压步进值，否则增加电压步进值。
通过设置第一预设时长和第二预设时长，控制频率调节环路和电压调节环路的控制比例。第一预设时长和第二预设时长可以通过目标缓启动时长乘上一定比例得到。
此外，一种理想的频率步进值和电压步进值设置结果是，通过仿真调试，根据缓启动的执行时长对频率步进值和所述电压步进值进行调试，以使缓启动先由电压调节环路控制，后由频率调节环路控制。具体地，可以使缓启动过程的前一半时间由电压调节环路控制，后一半时间由频率调节环路控制，或设置其他的控制时间比例。
上文详述了电源缓启动的控制方法对应的各个实施例，在此基础上，本发明还公开了与上述方法对应的电源缓启动的控制装置、设备及存储介质。
