WEET Tells You What should we pay attention to in the selection of a right rectifier bridge parameters?


按照现在电源行业：1、比例1:3的配比，也就是说整流桥电流选型应当大于实际工作电流的三倍。 例如设计一款小功率充电器，工作电流为300毫安大小的电路，那么选型整流 桥的电流则可以选择ASMEI半导体的DB107整流桥。倘若实际工作电流超过500 毫安，那么需要用DB207整流桥。与电路 工作电压不相同。2、整流桥其实就是由四个整流二极管芯片构成的桥式电 路，二极管芯片反向时受大功率电容放电与电路电压叠加产生的高压冲击，一 旦超过整流桥的承受范围，就会引发炸机的情况发生。设计电路时一定需要计 算到电路的叠加电压总和，已便于选择反向耐压更高的整流桥产品例如ASEMI 半导体DB107整流桥的反向耐压为100V，则电路中反向冲击电压不能超过1000V。总之选择整流桥额定电流必须是工作电流的三倍左右、

According to the current power industry: 1:3 ratio, that is to say, rectifier bridge current selection should be three times greater than the actual working current.

For example, if a low-power charger is designed with a working current of 300 mA, the DB107 rectifier bridge of WEE Technology can be selected as the current of the selected rectifier bridge. If the actual working current exceeds 500 mA, then DB207 rectifier bridge is needed. It is different from the working voltage of the circuit.

The rectifier bridge is actually a bridge circuit consisting of four rectifier diode chips. When the diode chip is reversed, it will be impacted by high voltage caused by the superposition of high power capacitor discharge and circuit voltage. Once it exceeds the endurance range of the rectifier bridge, it will trigger the explosion of the machine. When designing a circuit, it is necessary to calculate the sum of the superimposed voltage of the circuit.

It is convenient to choose a rectifier bridge product with higher reverse voltage withstand, such as WEE DB107 rectifier bridge whose reverse voltage withstand is 100V, and the reverse impulse voltage in the circuit can not exceed 1000V. In short, the rated current of the rectifier bridge must be about three times of the working current.
