Description

具太阳能充电功能的不间断电源
技术领域
本发明涉及一种不间断电源。
背景技术
所谓不间断电源(Uninterrupted Power Supply，UPS)，就是当停电时能够接替外接电源持续供应电力的设备，其电力来自于其内部的蓄电池。
如图1为现有的一种不间断电源的工作原理框图，一外接电源10’通过一滤波电路20’分别与一电源转换开关30’的一输入端及一外接电源充电电路40’的输入端相连，所述外接电源充电电路40’的输出端依次通过一蓄电池50’及一逆变器60’后与所述电源转换开关30’的另一输入端相连，所述电源转换开关30’的输出端与一用电设备70’(如电脑)的电源端相连。当所述外接电源10’正常工作时，所述电源转换开关30’控制所述外接电源10’直接给所述用电设备70’供电，同时所述外接电源10’通过所述外接电源充电电路40’给所述蓄电池50’充电，当外接电源10’发生故障或停电时，所述电源转换开关30’将控制所述蓄电池50’直接给所述用电设备70’供电，从而保证了用电设备70’可在外接电源10’短时间出现故障时仍可继续工作。
但是，当外接电源长时间出现故障或停电而蓄电池的电能又不能满足用电设备时，将会导致用电设备不得不停止工作。
发明内容
鉴于以上内容，有必要提供一种具太阳能充电功能的不间断电源，以使不间断电源长时间有效。
一种具太阳能充电功能的不间断电源，包括一蓄电池、一用于给所述蓄电池充电的外接电源充电电路、一太阳能板、一太阳能充电电路及一充电转换开关，所述太阳能板连接于所述太阳能充电电路的输入端，所述外接电源充电电路及太阳能充电电路的输出端连接于所述充电转换开关的输入端，所述充电转换开关的输出端与所述蓄电池充电端相连，所述充电转换开关控制所述外接电源充电电路及太阳能充电电路对所述蓄电池充电的转换。
相较现有技术，所述不间断电源增加了所述太阳能板及太阳能充电电路，并通过所述充电转换开关来实现外接电源与太阳能对蓄电池充电的转换，进一步提供了一种对蓄电池充电的方式，从而可实现更长时间为用电设备供电。
附图说明
下面参考附图结合具体实施方式对本发明作进一步的说明。
图1为现有一种不间断电源的工作原理框图。
图2为本发明具太阳能充电功能的不间断电源的较佳实施方式的工作原理框图。
具体实施方式
请参考图2，本发明具太阳能充电功能的不间断电源的较佳实施方式包括一滤波电路20、一电源转换开关30、一外接电源充电电路40、一蓄电池50、一逆变器60、一充电转换开关80、一太阳能板90及一太阳能充电电路100。
所述滤波电路20的输入端用于连接一外接电源10，其输出端分别连接所述电源转换开关30的一输入端及所述外接电源充电电路40的输入端，所述电源转换开关30的输出端用于连接一用电设备70，所述太阳能板90连接所述太阳能充电电路100的输入端，所述外接电源充电电路40的输出端及所述太阳能充电电路100的输出端连接于所述充电转换开关80的输入端，所述充电转换开关80的输出端与所述蓄电池50的充电端相连，所述蓄电池50又通过所述逆变器60连接于所述电源转换开关30的另一输入端。
当所述用电设备70通过所述具太阳能充电功能的不间断电源与所述外接电源10相接后，在所述外接电源10正常工作时，所述电源转换开关30将控制所述外接电源10直接给所述用电设备70供电，此时，所述充电转换开关80的初始状态为控制所述外接电源充电电路40给所述蓄电池50充电，当所述外接电源10出现故障或停电时，所述电源转换开关30将控制所述蓄电池50给所述用电设备70供电。如果所述外接电源10长时间处于故障或停电状态而使所述蓄电池50电量不足时，所述充电转换开关80将控制所述太阳能充电电路100给所述蓄电池50充电，从而可使所述蓄电池50持续给所述用电设备70供电。
本实施方式中，所述充电转换开关80还通过一微控制器120与一网络监控设备110(如服务器)相连，所述网络监控设备110可通过所述微控制器120强制控制所述充电转换开关80在所述外接电源充电电路40与所述太阳能充电电路100之间进行转换，当所述外接电源10正常工作时，用户可根据实际情况，通过所述网络监控设备110强制控制所述充电转换开关80控制所述太阳能充电电路100给所述蓄电池50充电，这样可在一定程度上节约能源。本处使用所述网络监控设备110来强制控制所述充电转换开关80是为了方便用户可进行远程控制，当不需要远程控制时，仅需设置一手动转换开关(未示出)来强制控制所述充电转换开关80的转换即可，所述手动转换开关连接于所述微控制器120的一控制引脚，可根据具体应用的微控制器来设置。
