宇阳科技推出的车规级谐振电容器,具有优良的温度特性、极低的ESR与损耗、优良的耐压特性,满足电动汽车需求
近年来,电动汽车(EV和PHEV等)的渗透率快速提高,但续航里程一直是制约其发展的关键问题。因此提高其续航能力,降低OBC(车载充电器)的DC-DC转换器损耗,提高其电力转换效率就变得至关重要。而采用LLC谐振型电路恰有助于提高DC-DC转换器的效率。
图1 LLC谐振的DC-DC模块电路
LLC转换器采用PFM方式,脉冲幅度需保持一定,并且通过开关频率进行控制,因此谐振电容器(Cr)要求拥有优良的温度特性与频率特性。据此,宇阳科技依据市场需求开发了谐振电容器。
宇阳产品优势
●优良的温度特性
在谐振电路的工作过程中,电容器需要在温度发生变化时表现出非常稳定的容值特性,这一点极为重要。宇阳车规级谐振电容器系列采用1类陶瓷材料(C0G),具备稳定的温度特性,满足温度范围内±30ppm/℃的容量变化率。
●极低的ESR与损耗
由于大电流会流经谐振电容器,使电容器产生热量,而宇阳车规级谐振电容系列的极低ESR只会损耗极低的能量,因此可减少发热,确保电路整体的稳定性。
●优良的耐压特性
LLC转换器适用于功率较大的电源,因此要求谐振电容器具备高耐压的特性。宇阳谐振电容系列可满足630Vdc~2000Vdc的高额定电压需求,可靠性试验耐电压能力可达到1.2~1.5Ur(依具体型号而定,参见宇阳规格书)
●优良的可靠性水平
宇阳谐振电容系列依托IATF16949体系,产品通过AEC-Q200认证测试,满足85℃-85%RH-额定电压-1000h、温度循环1000次等严苛环境可靠性测试要求。
材质特点
1类陶瓷MLCC(如C0G)相比于2类陶瓷MLCC(如X7R等)、薄膜电容器具备更优的温度特性与高频特性,非常适用于LC、LLC等谐振电路。
表 1
宇阳产品范围
宇阳车规级谐振电容系列的典型尺寸、静电容量、耐压等参数上限范围达到国际先进水平。
表2 宇阳车规级谐振电容系列产品范围
随着电动汽车市场的不断增长,谐振电容器的用量将会持续增加。宇阳科技凭借雄厚的技术实力与对产品应用的深入理解,推出的车规级谐振电容器系列已通过汽车行业龙头客户的测试与认证,批量向客户供应。未来,宇阳科技将持续拓展车规级电容器产品范围,满足车规市场需求。

【经验】多层陶瓷电容器(MLCC)常见失效模式之机械裂失效应对方法
在消费类电子中,经常会碰到电容短路失效的情况,电容常见失效模式分布中,机械应力裂占比最高,本文宇阳就机械应力裂这个模式做分享。导致电容失效的机械应力有很多种,但常见的主要是PCBA的弯曲、弯折及扭曲产生的应力及电容两焊端锡膏不一致对电容产生的应力。
