【应用】铝电解电容A704230/47用于工业电源/UPS,具有大容量,长寿命,宽温度范围等优势
工业电源和UPS通常对市电进行整流,功率因数校正,DC/DC及逆变等处理,输出单相,三相交流电,或者直流。为输出稳定的电压,降低电源纹波和噪声,在电源变换过程中都需要对电源滤波,使电源得到净化,更有利于设备供电品质的提高。
图1.UPS原理架构
如图1所示,一般中小型工业电源及UPS为开关电源,通常输入为单相220V/50Hz市电,因市电纹波,噪声及功率因数问题,通常在AC/DC变换的同时进行功率因数校正,然而通过DC/AC逆变和滤波输出频率,电压,纹波指标符合要求的220V/50Hz的高品质工业电源,在AC/DC、DC/DC及DC/AC过程中都会用到高耐压的大容量,大功率的铝电解电容。
图2. SNAPSIC系列铝电解电容在逆变电路母线电压滤波的应用
如图2所示,工业电源和UPS一般都有DC/AC逆变环节,经整流,功率因数校正后的直流电压一般较高,如单相220V/50Hz经整流后的最大直流电压可达311V,则母线最大直流电压可达311V,为逆变输出稳定,得到理想得输出电压,所以在逆变前保持母线电压得高质量,需对母线电压滤波,降低纹波。为保证电容的安全,需选择额定电压为400V-500V、电容范围100uF-470uF的电容。
本文主要推荐EXXELIA铝电解电容SNAPSIC系列产品,其中的A704230,470uF容值,额定电压450V,阻抗150mΩ;A704247的容值为470uF,额定电压为500V,阻抗250mΩ,非常适合用在这里。此外,这两款产品的直径35mm、高度为50mm,工作温度从-55°C~85°C,工作寿命为10 000 H / 85°C,寿命较长,使用稳定性较高。
该产品为直插焊接安装,安装时引脚具有自卡紧功能。在20°C下插脚和电容外壳之间的绝缘电阻为100 MΩ,自熄灭15 s(符合IEC 60 695-2-2)。该产品具有很强的抗冲击机械性能,通过严酷的冲击和振动试验。
综上,EXXELIA铝电解电容SNAPSIC系列的A704230、A704247具有大容量,长寿命,宽温度范围的特性,是工业电源/UPS滤波电容的优秀选择。
