具体实施方式
为了使本发明的内容更容易被清楚地理解，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述。
如图1至图3所示，一种适用于无人机的100W电池充电器，包括：主控芯片，所述主控芯片连接升压校正，所述升压校正与主控芯片均连接反激变压器，所述反激变压器连接输出同步整流，所述同步整流连接输出滤波、红绿转指示灯、恒压恒流控制及过压过流保护，所述输出滤波连接直流输出，所述红绿转指示灯、恒压恒流控制及过压过流保护均连接反馈模块，所述反馈模块连接主控芯片，交流电通过依次通过交流输入、输入滤波输入升压校正。

当电池电压在8-10.5V时，用0.6A的小电流进行修复性充电，缓慢提高电池电压；
当电池电压达到12.8V左右时，会线性提高充电电流，直至达到6A大电流,并进入恒流充电模式，快速提高电池电压；
当电池电压达到16.5V左右时，进入恒压区域减小充电电流，直至截止充电。
充电指示：
在正常充电状态，充电电流大于0.35A，充电器指示灯为红灯，表示充电状态。
在充满电状态时，充电电流小于0.1A，充电器指示灯为绿灯，表示充满电状态。
其中0.1A-0.35A为充电显示的滞回时间，防止红绿灯不断地交替闪烁。
以上所述仅为本发明专利的较佳实施例而已，并不用以限制本发明专利，凡在本发明专利的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明专利的保护范围之内。
