首先,对本申请涉及的若干名词进行介绍。
逆变器:是一种把直流(Direct Current,DC)电(电池、蓄电瓶)转变成定频定压或调频调压的交流(Alternating Current,AC)电的转换器。
参考图1,逆变器的工作原理包括:图中有S1~S4四个开关构成两个桥臂,开关S1和S2为同一个桥臂,S3和S4为一个桥臂。当开关S1和S4闭合,S2和S3断开,在其负载电阻上可得到Uo=Ud,当开关S2和S3闭合,S1和S4断开时,负载电阻上即可得到Uo=-Ud,这样以开关不断进行操作,在负载上就得到了交流波形,完成直流变为交流的过程。
需要说明,同一桥臂上的开关不能同时闭合,以免造成电源短路,通过改变开关的频率即可改变交流电的频率。实际上,上图中的四个开关是各种半导体开关器件的理想模型,逆变电路中常用的半导体开关器件有晶闸管、场效应管和绝缘栅晶体管(IGBT)。
上面只是逆变器的基本原理,当然实际应用中,现有的逆变器可以比图1所示的逆变器复杂,比如:参考图2所示的逆变器,该逆变器包括主电路、控制电路、驱动电路和辅助电源等,本实施例对此不作限定。
其中,主电路包括各种完成逆变的开关电路,包括直流电源(电容)、缓冲器、开关桥;路、滤波器和变压器,完成能量级别的处理。
控制电路用于采集主电路反馈量,实现控制算法和保护策略,得到开关管开关信号。
驱动电路用于根据控制板的开关信号,驱动保证场效应管等开关器件的可靠开通和关断。
辅助电源是指控制芯片、驱动芯片的辅助电源电路。
上述逆变器由于仅包括一个直流电输入接口和一个交流电输出接口,因此,该逆变器仅能够实现将直流电转换为交流电的功能,且该直流电输入接口只能适用一种接口类型的电源。在一些场景中,比如:直流电的接口类型不同,使用直流电为外设充电的场景,现有的逆变器均不适用。
基于上述技术问题,本申请对现有的逆变器进行改进。逆变器具有多个输入接口,包括:直流电输入接口,包括第一直流电输入接口和第二直流电输入接口;交流电输入接口;与直流电输入接口和交流电输入接口相连的控制组件;通过控制组件控制与直流电输入接口连通或断开的第一电路结构和第二电路结构;以及,通过控制组件控制与交流电输入接口连通或断开的第三电路结构。
第一电路结构用于将直流电转换为交流电,输入端可通断地与第一直流电输入接口或第二直流电输入接口相连,输出端为逆变器的交流电输出端。
第二电路结构维持直流电模式,输入端可通断地与第一直流电输入接口相连,输出端可通断地与第二直流电输入接口相连。
第三电路结构用于将交流电转换为直流电,输入端可通断地与交流电输入接口相连,输出端可通断地与第二直流电输入接口相连。
一方面,由于直流电输入接口包括至少两个,因此,可以根据不同的直流电源接口的类型设计相匹配的逆变器的直流电输入接口的类型,以实现将具有不同接口类型的直流电源的直流电转换为交流电。
另一方面,由于逆变器中设置有第二电路结构,该第二电路结构可以与第一直流电输入接口和第二直流电输入接口连通,第二电路结构维持直流电模式,因此,可以实现与第一直流电输入接口的第一直流电源为与第二直流电输入接口相连的第二直流电源充电,即,使用直流电为外设充电。
又一方面,由于逆变器还设置有交流电输入接口,并设置有第三电路结构,该第三电路结构具有将直流电转换为交流电的功能,因此,可以实现使用交流电提供直流电供电电源的场景。
上述的第一直流电源可以是点烟器,第二直流电源可以是电池包;交流电源可以是市电;当然,第一直流电源和第二直流电源也可以是其它类型的直流电源,交流电源也可以是其它类型的交流电源,本实施例对此不作限定。
点烟器(又称为雪茄头):是汽车中的零部件。点烟器通常与车载逆变器配合使用,以将汽车上的直流电转换为交流电,从而为移动电子设备充电,比如:为手机、平板电脑等设备充电。
电池包:是指电能储存装置,包括至少一个电池,在为用电设备供电时放点;也可以使用外界的电源给电芯充电。

另外,通过设置电压检测电路和电量指示组件,通过电压检测电路检测第二直流电源的充电电量,通过电量指示组件指示电压检测电路检测到的充电电量,可以实现通过逆变器指示充电电量的功能。
另外,通过设置照明电路结构,可以通过逆变器实现照明功能。
