This paper proposes an improved bidirectional LLC resonant topology with a new control scheme. All the switches in the proposed topology can achieve soft switching. Compared with traditional isolated bidirectional dc-dc converters such as dual active bridge converter, the reverse energy and turn-off loss are reduced dramatically, and the conversion efficiency can be much improved. With the ...
This paper proposes a new LLC resonant DC-DC topology with bidirectional power flow capability. All the switches in the proposed topology can achieve zero voltage switching (ZVS) at turn on, and zero current switching (ZCS) is achieved for the output side switches at turn off. Compared with the traditional bidirectional dual active bridge (DAB) converter, the turn off current is greatly ...

你好,借楼问个问题,我目前项目需要一个±5v的电压轨,选择的方案是tps65131+tps7a4901+tps7a3001,经过电容、电感滤波,输出电压高频开关噪声峰峰值在两个轨都在40mv的水平,由于我运放最终输出在100mv的水平,我觉得这样的电压轨噪声应该会对我的结果产生影响,但是并不确定会有多大的程度。

在设计开发板的过程中,我们的电子元件经常要使用到各种电压,这些电压一般情况下由更高的电压降压获得,比如我们有电源 12v,想获得 5v 和 3.3v 电压,就可以使用降压芯片来降压获得,但电源设计时也需要注意一些要点,注意一下降压芯片和降压电路使用场景。

有办法让移动电源实现12v1a的输出吗,路由器圆口的接口一般5v2a输出的移动电源,外接升压器可以提供12v直流电,但最多只能转换到0.75a左右。要达到12v1a足流,须选用输出5v3a以上的移动电源,或者将两个移动电源输出并联。升压器...
