【应用】大功率无感电阻TR20系列提升功率开关器件RCD缓冲吸收性能

时间： 2020-01-26 来源：世强

技术问答

功率开关器件的开通和关断一般都是瞬间完成，而实际在逆变电路中，功率开关器件关断时刻下降的电流和上升的电压有重叠时间，因此会有较大的损耗。为了使功率开关器件在关断电压能够得到有效的抑制并减小损耗，通常都会增加缓冲吸收电路。

对于缓冲吸收电路的当要求一般尽量减小主回路的电感，如图1所示是一个典型的MOS管的RCD缓冲系数电路，其电阻应采用低感最好是无感的吸收电阻，二极管应选用快开通和快速回复的二极管，以免产生开通过电压和反向恢复引起较大的振荡过电压。其参数计算选型可以参考：

首先计算电容参数C=IDS(tr+tf)/Vds，其中IDS为功率开关管上的电流，tr和tf为上升和下降时间，Vds为DS两端电压，然后根据电容参数计算电阻参数R=ton/3C；

图1 功率MOS管典型RCD缓冲吸收电路示意图

针对这一应用，推荐光颉科技（Viking）TR20系列大功率无感电阻。其采用一种平面工艺功率无感电阻，采用TO-220厚膜封装，相对传统电阻，电阻本身电感值很小，频率响应特性优异，广泛用于中、高频电路中，如RCD吸收电路；其伏安特性为线性，电气性能稳定，有良好的绝缘特性，用于检测设备内的分压电阻；同时过载能力强，特别适用于间歇式供电和脉冲大电流电路，机械强度高，可耐冷和热冲击。

TR20系列大功率无感电阻特点：

·符合RoHS标准

·工作温度范围均为-65~150°C

·温度系数（TCR）最小值为±50PPM/°C，最大值为±300PPM/°C

·均采用TO-220封装方式

·厚膜电阻

·无感电阻设计
