图5是根据本申请实施例提供的电源装置的控制方法的流程图，如图5所示，该方法包括如下步骤：
步骤S501，在第一输入电源20供电的情况下，控制第一继电器S1的第一接入点和第一继电器S1的第三接入点闭合，第一继电器S1的第二接入点和第一继电器S1的第四接入点闭合，第三继电器S3的公共接入点与第三继电器S3的第一接入点闭合，第四继电器S4的公共接入点与第四继电器S4的第一接入点闭合。
例如，在第一输入电源20正常供电时，闭合第一继电器S1的第一接入点和第一继电器S1的第三接入点，闭合第一继电器S1的第二接入点和第一继电器S1的第四接入点，闭合第三继电器S3的公共接入点与第三继电器S3的第一接入点，闭合第四继电器S4的公共接入点与第四继电器S4的第一接入点，即将第一输入电源20接入电路中。第一输入电源20通过第一继电器S1，第三继电器S3和第四继电器S4为负载60供电。
步骤502，检测第一输入电源20是否存在异常情况，其中，异常情况至少包括以下之一：过压情况，欠压情况和掉电情况。
例如，在第一继电器S1，第三继电器S3和第四继电器S4导通期间检测第一输入电源20是否有异常情况，该异常情况包括过压情况(Over Voltage)，欠压情况(Brown out)和掉电情况(Dropout)。
步骤S503，当第一输入电源20存在异常情况时，控制第一继电器S1的第一接入点和第一继电器S1的第三接入点断开，第一继电器S1的第二接入点和第一继电器S1第四接入点断开，第三继电器S3的公共接入点与第三继电器S3的第二接入点闭合，第四继电器S4的公共接入点与第四继电器S4的第二接入点闭合，第二继电器S2的第一接入点和第二继电器S2的第三接入点闭合，第二继电器S2的第二接入点和第二继电器S2的第四接入点闭合。
例如，当检测出第一输入电源20存在异常情况时，断开第一继电器S1的第一接入点和第一继电器S1的第三接入点，断开第一继电器S1的第二接入点和第一继电器S1的第四接入点，闭合第三继电器S3的公共接入点与第三继电器S3的第二接入点，闭合第四继电器S4的公共接入点与第四继电器S4的第二接入点，闭合第二继电器S2的第一接入点和第二继电器S2的第三接入点，闭合第二继电器S2的第二接入点和第二继电器S2的第四接入点，即将输入电源由第一输入电源20切换至第二输入电源30。第二输入电源30通过第二继电器S2，第三继电器S3和第四继电器S4为负载60供电。
综上所述，通过自动转换开关10中的继电器的闭合与断开，自动实现输入电源的切换工作，避免采用双路冗余供电模式，降低了电源装置的成本问题。
可选地，在本申请实施例提供的电源装置的控制方法中，在控制第一继电器S1的第一接入点和第一继电器S1的第三接入点断开，第一继电 器S1的第二接入点和第一继电器S1的第四接入点断开之前，该方法还包括：关闭用于驱动功率因数校正电路40工作的驱动信号；在控制第二继电器S2的第一接入点和第二继电器S2的第三接入点闭合，第二继电器S2的第二接入点和第二继电器S2的第四接入点闭合之后，该方法还包括：检测功率因数校正电路40的输入电压值与第二输入电源的电压值是否相符，在功率因数校正电路40的输入电压值与第二输入电源的电压值相符的情况下，恢复用于驱动功率因数校正电路工作的驱动信号。
具体地，在检测到第一输入电源20存在异常时，首先要关闭驱动功率因数校正电路40工作的驱动信号，然后进行第一继电器S1的断开工作。闭合第二继电器S2之后，检测功率因数校正电路40的输入电压值与第二输入电源的电压值是否相符，这里的相符是说两个电压值相等或者近似相等。当功率因数校正电路40的输入电压值与第二输入电源的电压值相符时，再恢复驱动功率因数校正电路40工作的驱动信号。这样的操作是为了保证第二继电器S2已完全闭合，即第二输入电源30第二输入电源30已成功接入电路中，避免功率因数校正电路40作无用功。
可选地，在本申请实施例提供的电源装置的控制方法中，在控制第二继电器S2的第一接入点和第二继电器S2的第三接入点闭合，第二继电器S2的第二接入点和第二继电器S2的第四接入点闭合之后，该方法还包括：检测第一输入电源20是否恢复至正常情况；当第一输入电源20恢复至正常状态时，控制第二继电器S2的第一接入点和第二继电器S2的第三接入点断开，第二继电器S2的第二接入点和第二继电器S2的第四接入点断开，第三继电器S3的公共接入点与第三继电器S3的第一接入点闭合，第四继电器S4的公共接入点与第四继电器S4的第一接入点闭合，第一继电器S1的第一接入点和第一继电器S1第三接入点闭合，第一继电器S1的第二接入点和第一继电器S1第四接入点闭合。
例如，在第二输入电源30供电期间，检测第一输入电源20是否恢复至正常情况。当第一输入电源20恢复至正常状态时，自动切换开关就开始启动将输入电源切换回第一输入电源20的操作。断开第二继电器S2的第一接入点和第二继电器S2的第三接入点，断开第二继电器S2的第二接入点和第二继电器S2的第四接入点，闭合第三继电器S3的公共接入点与第三继电器S3的第一接入点，闭合第四继电器S4的公共接入点与第四继电器S4的第一接入点，闭合第一继电器S1的第一接入点和第一继电器S1的第三接入点，闭合第一继电器S1的第二接入点和第一继电器S1的 第四接入点，实现通过第一输入电源20进行供电。
在第一输入电源20处于正常状态时，可以自动实现将输入电源由第二输入电源30切换回第一输入电源20，保证通过第一输入电源20为负载60工作，提高电源装置的可靠性。
可选地，在本申请实施例提供的电源装置的控制方法中，在控制第二继电器S2的第一接入点和第二继电器S2的第三接入点断开，第二继电器S2的第二接入点和第二继电器S2的第四接入点断开之前，该方法还包括：关闭用于驱动功率因数校正电路40工作的驱动信号；在控制第一继电器S1的第一接入点和第一继电器S1的第三接入点闭合，第一继电器S1的第二接入点和第一继电器S1的第四接入点闭合之后，该方法还包括：检测功率因数校正电路40的输入电压值与第一输入电源的电压值是否相符，在功率因数校正电路40的输入电压值与第一输入电源的电压值相符的情况下，恢复用于驱动功率因数校正电路40工作的驱动信号。
具体地，在检测到第一输入电源20恢复正常时，首先关闭用于驱动功率因数校正电路40工作的驱动信号，然后断开第二继电器S2，闭合第一继电器S1之后，检测功率因数校正电路40的输入电压值与第一输入电源的电压值是否相符，当功率因数校正电路40的输入电压值与第一输入电源的电压值相符，再恢复驱动功率因数校正电路40工作的驱动信号。这样的操作是为了保证第一继电器S1已完全闭合，即第一输入电源20已成功接入电路中，避免继电器正在切换过程中，功率因数电路就开始发波，导致继电器带载切换，容易造成继电器损坏。
本申请实施例提供的电源装置的控制方法，通过在第一输入电源20供电的情况下，控制第一继电器S1的第一接入点和第一继电器S1的第三接入点闭合，第一继电器S1的第二接入点和第一继电器S1的第四接入点闭合，第三继电器S3的公共接入点与第三继电器S3的第一接入点闭合，第四继电器S4的公共接入点与第四继电器S4的第一接入点闭合；检测第一输入电源20是否存在异常情况，其中，异常情况至少包括以下之一：过压情况，欠压情况和掉电情况；当第一输入电源20存在异常情况时，控制第一继电器S1的第一接入点和第一继电器S1的第三接入点断开，第一继电器S1的第二接入点和第一继电器S1第四接入点断开，第三继电器S3的公共接入点与第三继电器S3的第二接入点闭合，第四继电器S4的公共接入点与第四继电器S4的第二接入点闭合，第二继电器S2的第一接入点和第二继电器S2的第三接入点闭合，第二继电器S2的第二接入点和 第二继电器S2的第四接入点闭合，解决了相关技术中采用双路冗余供电模式，双路冗余供电模式下需要配置两套电源装置，导致成本比较高的问题。通过控制自动转换开关10中的继电器的闭合与断开，实现两路输入电源的切换工作，避免采用双路冗余供电模式，进而达到了降低成本的效果。
图6为根据申请实施例提供的可选的第一输入电源20出现欠压情况(brown out)时的控制时序图。Brown-out代表输入电压低于预设值；以交流为例，通常176V～300Vac认为是正常值，低于176V就可以认为是Brown-out了。
具体控制方法为：t0时刻，第一输入电源20开始上电，第一继电器S1闭合，第三继电器S3的公共接入点与第三继电器S3的第一接入点闭合，第四继电器S4的公共接入点与第四继电器S4的第一接入点闭合，PFC和DCDC开始发波；
