Description

一种正反激式开关电源电路
技术领域
本发明涉及充电技术领域，尤其涉及一种正反激式开关电源电路。
背景技术
当前的铅酸蓄电池充电机都以三段充电式或者小电流恒流充电，这种充电器结构虽然结构简单，但其充电时间过长，最起码8个小时以上，其原因为其充电电流值设定的都比较小，导致充电时间太长。
发明内容
本发明的目的就是为了克服上述现有技术存在的缺陷，提供一种充电时间短的正反激式开关电源电路。
本发明的目的可以通过以下技术方案来实现：一种正反激式开关电源电路，其特征在于，该电路包括开关变压器、二极管I、二极管II、二极管III、二极管IV、电容，所述的二极管I的阴极与开关变压器的次级线圈正极连接，阳极与电路的负输出端连接；所述的二极管II阳极与开关变压器的次级线圈正极连接，阴极与电路的正输出端连接；所述的二极管III的阴极接在开关变压器的次级线圈中部，阳极与电路的负输出端连接；所述的二极管IV的阳极与开关变压器的次级线圈负极连接，阴极与电路的正输出端连接；所述的电容并联在电路输出端的两端。
电路分正向激励和反向激励：
正向激励时，开关变压器1端为正，次级同名端3端也为正，对应的4端为负。此时二极管II、二极管III导通，次级线圈的3端和4端的能量储存在电容中
反向激励时，开关变压器1端为负，次级同名端3端也为负，对应的5端为正。此时二极管II、二极管III关断，二极管I、二极管IV导通，次级线圈的3端和5端的能量储存在电容中，有效的利用了开关变压器磁芯中泄放的能量。
与现有技术相比，本发明的优点在于在开关电源上采用了正激反激方式，这样可以使电能充分利用，提高充电效率，正激时，电网的能量直接储存在电容里，反激时使电感内储存的能量有效的加以利用，减少了充电器耗电量，这种电路对电容充电的全过程无稳压要求，只对上限电压加以控制。
附图说明
图1是本发明一种正反激式开关电源电路的结构图。
具体实施方式
如图1所示，一种正反激式开关电源电路，该电路包括开关变压器T、二极管ID1、二极管IID2、二极管IIID3、二极管IVD4、电容C，所述的二极管ID1的阴极与开关变压器T的次级线圈正极连接，阳极与电路的负输出端B连接；所述的二极管IID2阳极与开关变压器T的次级线圈正极连接，阴极与电路的正输出端A连接；所述的二极管IIID3的阴极接在开关变压器T的次级线圈中部，阳极与电路的负输出端B连接；所述的二极管IVD4的阳极与开关变压器T的次级线圈负极连接，阴极与电路的正输出端A连接；所述的电容C并联在电路的输出端两边。
本发明包含电感线圈T、正激回路(D2-D3)、反激回路(D4-D1)，由开关管将能量以高频打入电感线圈T中，正激时用次级线圈的3端和4端；对电容充电；反激时用次级线圈的3端和5端，3端到5端的匝数是3端到4端匝数的两倍，对同样的输出负载来说，能充分的释放磁芯中储存的能量，并把能量转化到电容里，这样可以避免磁饱和，减少功率管故障率。
