为了解决背景技术中提及的问题，根据本实施例的一方面，提供了一种相位同步工作电路的实施例。
下面将结合具体实施方式，对本实施例提供的一种相位同步工作电路进行详细的说明，图1为负载控制框图，如图1所示，相位同步工作电路包括：包括直流电源、逆变器、电子开关模块组和控制器(图中未画出)。直流电源的直流输出端与逆变器的直流输入端相连，逆变器包括第一交流输出端AC1和第二交流输出端AC2，第一交流输出端AC1与电子开关模块组的输入端相连接，第二交流输出端AC2包括至少两个输出端A1和A2，且电子开关模块组的每个输出端均与逆变器的第二交流输出端AC2组成一个负载连接端组，这样构成至少两个负载连接端组，负载连接端组用于连接负载。控制器的输出端与电子开关模块组的控制端相连接，能够控制电子开关模块组的开闭，以通过电子开关模块组对每个负载连接端组进行的供电或断电。
本申请将多个负载的开关使能(电子开关模块组)放在逆变器的后端，即多个负载连接端组采用同一个逆变器控制，逆变器输给每个负载连接端组的信号相位都是一样的，那么多个负载在开启时不存在相位差，提高负载工作效果。
可选地，相位同步工作电路还包括至少一个负载，每个负载与任意一个负载连接端组相连接，在电子开关模块组闭合时负载进行工作。
其中，多个负载采用同一个电子开关模块组进行控制。
在一种实施例中，电子开关模块组可以只包括一个电子开关模块，全部负载对应一个电子开关模块，这样电子开关模块组闭合时，多个负载连接端组同时供电，多个负载会同时工作，由于多个负载的相位差相同，不会产生不好的影响，例如共振噪声。
在另一种实施例中，电子开关模块组还可以包括多个电子开关模块，每个负载对应一个电子开关模块，控制器可以控制部分电子开关模块闭合，还可以控制电子开关模块在不同的时刻闭合，从而控制不同的负载连接端在不同时刻供电，这样即使多个负载在不同时刻开始工作，由于采用共同的一个逆变器，多个负载的相位差也是相同的，提高负载工作效果。
图2为不同负载在不同时刻开启时的驱动波形示意图，图中位于上方的波形为第一个开启负载的驱动波形，图中位于下方的波形为第二个开启负载的驱动波形，第二个负载在任意时刻开启其相位都能和第一个负载的相位保持一致。
在本实施例中，电子开关模块包括继电器、三极管、第一偏压电阻和第二偏压电阻，继电器的输入端与逆变器的第一交流输出端连接，继电器的输出端与负载的一端连接，继电器的线圈的一端连接直流电源。三极管的集电极和继电器的线圈的另一端连接，三极管的发射极接地。第一偏压电阻的一端连接控制器的输出端，第一偏压电阻的另一端连接三极管的基极。第二偏压电阻的一端与第一偏压电阻的另一端和三极管的基极均连接，第二偏压电阻的的另一端接地。
图3为两个负载控制原理框图，可以看出，直流电源的直流输出端与逆变器的直流输入端相连，逆变器的第一交流输出端AC1分别与继电器K1、继电器K2的公共开关端相连，逆变器的第二交流输出端AC2与负载1的另一端、负载2的另一端相连，继电器K1的非常闭 触点A1与负载1的一端相连、继电器K2的非常闭触点A2与负载2的一端相连，继电器K1的线圈的一端、继电器K2的线圈的一端连接直流电源，继电器K1的线圈的另外一端、继电器K2的线圈的另外一端分别与三极管Q1、三极管Q2的集电极相连，三极管Q1、三极管Q2的基极通过第一偏压电阻R1与MCU的GPIO(General-Purpose Input/Output Ports，通用I/O端口)相连，还通过第二偏压电阻R2接地。
具体地，在三极管的基极检测到高电平的情况下，三极管导通。继电器用于在三极管导通时上电吸合，以使负载通过继电器与逆变器的第一交流输出端连通。这样，控制器MCU控制三极管的基极为高电平，此时三极管导通，继电器在三极管导通时上电吸合，负载通过继电器与逆变器的第一交流输出端AC1连通。在电子开关模块闭合时，逆变器的第一交流输出端和第二交流输出端输出频率相同、相位差为180度的两个方波，第一交流输出端和第二交流输出端加在负载的两端形成交流信号，从而驱动负载工作。示例性地，逆变器的两个交流输出端都输出50zH的相位差为180度的方波，两个交流输出端加在负载的两端形成一个50zH的交流信号。
作为一种可选的实施方式，本申请还提供了一种相位同步工作方法，相位同步工作方法包括：发送闭合信号至电子开关模块组，以使逆变器的两个交流输出端经过闭合的电子开关模块组后在负载的两端形成交流信号，以驱动负载工作，其中，电子开关模块组和逆变器的至少一个交流输出端连接，至少两个负载的驱动相位均相同。
具体地，控制器发送闭合信号至电子开关模块组，电子开关模块组中的电子开关模块闭合，逆变器的两个交流输出端经过闭合的电子开关模块组后在负载的两端形成交流信号，以驱动负载工作，由于电子开关模块组和逆变器的交流输出端连接，同一个逆变器输出的相位差相同，因此负载的驱动相位均相同，不会产生共振噪声。
作为一种可选的实施方式，电子开关模块组包括多个电子开关模块，每个负载对应一个电子开关模块，发送闭合信号至电子开关模块组的步骤包括：根据控制指令确定待启动的至少两个负载；确定待启动的负载对应的电子开关模块；控制电子开关模块中的三极管导通，以使和三极管连接的继电器上电吸合。
具体地，控制器确定待启动的至少两个负载后，确定每个负载对应的电子开关模块，然后控制电子开关模块中的三极管导通，继电器由于三极管导通从而上电吸合，该负载和逆变器的交流输出端连通，逆变器的两个交流输出端在负载两端形成交流信号，负载开始工作。
具体地，每个负载配置一个电子开关模块，控制器通过对每个负载的电子开关模块进行单独控制，可以避免电子开关模块组损坏导致全部负载都无法使用。
基于相同的技术构思，本实施例还提供了一种相位同步工作装置，该相位同步工作装置包括：
发送模块，用于发送闭合信号至电子开关模块组，以使逆变器的两个交流输出端经过闭合的电子开关模块组后在至少两个负载的两端形成交流信号，以驱动负载工作，其中，电子开关模块组和逆变器的至少一个交流输出端连接，至少两个负载的驱动相位均相同。
在一个可选的实施例中，电子开关模块组包括多个电子开关模块，每个负载对应一个电子开关模块，发送模块用于：
根据控制指令确定待启动的至少两个负载；确定待启动的负载对应的电子开关模块；
控制电子开关模块中的三极管导通，以使和三极管连接的继电器上电吸合。
