Description

一种具有Type-C接口的充电器 技术领域
本发明涉及充电器，具体涉及一种具有Type-C接口的充电器。
背景技术
随着移动终端功能越来越多，在日常生活中被使用得越来频繁，耗电量很大，电池的容量是有限的，如何实现快速充电，尽快地将电池充满，是各大厂商的研发重点。一般来说，充电功率超过10W才能称之为快速充电。对于功能机，手机耗电都不是很大，USB的5V 0.5A就可以满足需求；当智能机出现之后，由于对性能的大幅度渴求导致功耗上升，0.5A已经满足不了需要了；于是定义了一个增强的USB充电识别标准：BC 1.2，将充电电流扩展到5V 1.5A。然而对于3000毫安时以上的智能手机，这个时候就算是5V 1.5A也不能满足需求了，于是充电电流再次扩展到5V 2A，也就是高通的QC 1.0技术。
然而充电电流并不能被在无限制地被扩展，当达到5V 2A之后，电流再增加势必造成接口和数据线无法承受。一般来说只能在2A的电流下保证安全高效的传输，极限的情况下最大可至3A。在负载不变的情况下为了提高充电功率，便转而提高充电器到USB接口的电压。高通QC2.0上设计了两种方案----A类和B类，手机使用的A类可以提供输出5V、 9V、12V三种电压，实际上基本上都只用9V这个档位。平板或笔记本使用的B类方案电压将支持到5V、9V、12V、20V四种电压，功率可以达到60W。进一步，高通QC3.0以200mV增量为一档，使得电压从3.6V到20V电压可灵活选择。
另外，现在的快充技术，各大厂商都有自己的识别协议，但并不是没有大一统的识别协议，USB推广小组早在2012年7月份就制定了USB PD充电协议，全称“USB Power Delivery Specification”。USB PD根据可供给的电力设定了10W、18W、36W、60W、100W五级规格。PD技术不仅充电功率强悍，而且可以实现双向充电。
前面提到，电流再增加势必造成接口和数据线无法承受，由于Type-C接口的触点数量数倍于Type A接口，这就使得它能承受的电流强度大大增加，同样的电流下，Type-C充电电流损失也更小。然而，目前市面上的移动终端大多还是以USB 2.0标准为主流，Type-C不能兼容现有Type A设备。

当所述墙插变压部分1被单独使用，第一身份识别模块19用于与移动终端进行身份识别。当移动终端通过第一接口母头11与墙插变压部分1相连接，主控制器17利用USB PD的电源IC(即电源的脉宽控制集成)从所述第一接口母头11获取移动终端的参数信息，判断移动终端能够接受的最高电压(大于5V)、最大电流值和脉宽以及移动终端的类型。若身份识别成功，主控制器17进行逻辑控制，使得变压器10输出所述移动终端能够接受的最高电压，通过所述第一接口母头11对移动终端进行快速充电；若身份识别不成功，主控制器17发出逻辑控制指令，使得变压器10输出5V(2A)电压，通过所述第一接口母头11对移动终端进行5V2A的普通充电。所述身份识别的协议符合QC3.0协议，并通过中间两线(D+D-)上加载电压和密钥来识别。
所述主控制器17分别与所述整流器16、所述PWM控制器18、变 压器10和所述第一接口母头11相连接进行逻辑控制。根据所述主控制器17输出的逻辑控制指令，所述整流器16将交流市电整流为高压直流电压。优选地，整流器16前还连接有第一滤波器101，对输入的交流市电滤波，滤除交流电压的高频谐波、畸变和噪声；整流器16后还连接有第二滤波器102，对整流后的高压直流电压滤波，滤除高压直流电压的高频谐波、畸变和噪声，使得整流器16输出的高压直流电压无谐波、无噪声、质量更好。
所述墙插变压部分1还包括光电感应器112，所述主控制器17通过控制所述调节光电感应器112的导通强弱来设定所述PWM控制器18的脉宽，使所述PWM控制器18输出的脉宽稳定在与移动终端相匹配的范围。根据所述PWM控制器18输出的脉宽范围，所述变压器10将高压直流电压降压为低压直流电压，实现DC/DC变换。
优选地，还将利用同步整流控制器103对经所述变压器10降压后的低压直流电压进行同步整流，即采用通态电阻极低的专用功率MOSFET，降低整流损耗，大大提高变压器的DC/DC变换效率，所述同步整流控制器103与所述变压器10相连接。
所述墙插变压部分1还包括电压反馈模块113，所述主控制器17通过所述电压反馈模块113对所述变压器10输出的低压直流电压进行反馈 调节,以校正变压器10输出的低压直流电压值。
所述低压直流电压经过所述第一接口母头11输出，可实现对移动终端的充电。优选地，所述墙插变压部分1还包括，在所述第一接口母头11与所述变压器10之间，连接有主回路开关114，所述主控制器17控制所述主回路开关114的导通或断开来决定是否为移动终端充电。当充电器检测到充电过程中过流(即超过所述最大电流)或过压(即超过所述最大电压)时，根据USB PD技术的电源IC，主控制器17将断开主回路开关114，立即停止对移动终端充电，对充电器和移动终端予以保护，待电流或电压恢复正常时,再恢复对移动终端充电。
如图5所示是本实施例提供的一种具有Type-C接口的充电器的接口转换部分结构框图，所述接口转换部分2包括第一接口公头21、接口转换模块28、第二身份识别模块29、第二接口22和第三接口23。
所述第二接口22或所述第三接口23通过接口转换模块28与所述第一接口公头21相连接。当所述第一接口公头21与所述第一接口母头11对接，使得所述墙插变压部分1和所述接口转换部分2相连接，所述墙插变压部分1和所述接口转换部分2被组合起来用于对移动终端充电。
所述第二接口22与所述第三接口23并联，二者为Type-C接口、Type A接口或Type B接口，且二者之中至少有一个是Type A接口。
当所述墙插变压部分1和所述接口转换部分2被组合起来用于对移动终端充电时，移动终端通过第二接口22或第三接口23与所述接口转换部分2相连接。所述第二身份识别模块29先与所述墙插变压部分1的第一身份识别模块19进行身份识别，若身份识别成功，主控制器17利用USB PD技术的电源IC从所述第二接口22或所述第三接口23获取移动终端的参数信息，判断移动终端能够接受的最高电压(大于5V)、最大电流值和脉宽以及移动终端的类型。之后，第二身份识别模块29再与移动终端进行身份识别协议识别，若身份识别再次成功，主控制器17进行逻辑控制，使得变压器10输出所述移动终端能够接受的最高电压，通过所述第二接口22或所述第三接口23对移动终端进行快速充电；若有一次身份识别不成功，主控制器17进行逻辑控制，使得变压器10输出5V(2A)电压，通过所述第二接口22或所述第三接口23对移动终端进行5V2A的普通充电。所述身份识别协议符合QC3.0协议，并通过中间两线(D+D-)上加载电压和密钥来识别。
综上所述，由于所述墙插变压部分既可独立使用又可与所述接口转换部分相连接后组合使用，使得本申请所述充电器灵活方便、可进行多模式使用，在组合使用时兼容了Type-C接口、Type A接口或Type B接口；由于所述充电器具有的Type-C接口符合USB3.1标准以及USB PD 协议，使得所述充电器可根据移动终端能够接受的最高电压、最大电流值和脉宽以及移动终端的类型对充电设备快速充电,其充电功率最高可达100W，同时使得所述充电器具有快速的数据传输速度，其数据传输速度可达10Gps；由于具有身份识别协议，并通过中间两线(D+D-)上加载电压和密钥来识别，使得充电器能够对移动终端充电更安全，识别成功时对移动终端快速充电，识别不成功时对移动终端普通充电，既让移动终端能够获得充电又保障了移动终端免于受到过高电压、电流的损害。
以上应用了具体优选实施例对本发明进行阐述，只是用于帮助理解本发明，并不用以限制本发明。对于本领域的一般技术人员，依据本发明的思想，可以对上述具体实施方式进行变化。
