SCMT型 单个或双个IGBT突波吸收密封盒装电容器 Type SCMT Single/Dual IGBT Snubber Capacitor Modules 用途 Applications 使用SCMT型目的就像是放电限制分离耦合，是保护双IGBT模块。 Use style SCMT as a discharge restrictive de-coupling to protect dual IGBT modules from overvoltage, Figure 1. Style SCMT 如图1，SCMT型也是有“N”型或“P”型突波吸收电容，各对一个IGBT.。 may also be used as an “N” or “P” type snubber component for a clamp snubber where single IGBT modules are used, Figure 2. 特点 Highlights 可直接安装在IGBT上 • Mount directly to the IGBT module • Low inductance 一条或者两条引线可连接到电阻上 • UL94VO阻燃环氧树脂封装 低电感 • Low Loss • Hyperfast diodes integrated into package 放电限制分离偶合 Other terminal pitches and capacitance values available. 使用环保材料 内装快恢管 • Flame resistant case and epoxy, meets UL 94VO 各种间距的电容器可供选择 低损耗 • 1 or 2 wire taps for connecting external resistor • RoHS Compliant RCD吸收回路 Discharge Restrictive De-coupling RCD Clamp 在图1中的线路中操作上与放电限制分离耦合一样， 这种突波吸收功能就像一个夹子，如图2，在关断时， The circuit in Figure 1 operates on the same principles as the de-coupling capacitor, but only The function of this snubber is similar to a clamp, Figure 2. At turn-off, the snubber diode is forward 但只有在关閉转换时， 于是就产生了突波吸收的作用。感性线圈中产生的能量 during turn-off switching. As the IGBT turns biased and the snubber is activated. The energy off, energy trapped in the loop inductance is trapped in the stray inductance is absorbed by the 当IGBT关的时候，感性线圈中的能量被转移到电容上。 被突波吸收电容吸收了. 当打開时，突波吸收电容 transferred to the capacitor. The diode blocks snubber capacitor. During turn-on the snubber oscillations from occurring and excess charge on caps that were fully charged to bus voltage have 从充电到充电过于饱和，通过电容内部电阻，二极管阻止了振荡。 通过母线电压充至饱和，放电回路二极管的正向偏置， the capacitor is discharged through the external a discharge path through the forward biased resistor. free-wheel diode, the IGBT, and the snubber IGBT，突波吸收电容电阻。这样会减少反向瞬间电压. resistors. This reduces the reverse recovery voltage transient. CDE Cornell Dubilier•1605 E.
