在几乎所有的工业控制系统中，变频驱动器(VFDs)/逆变器通常安装在电机的前端，以调节速度和节约能源。根据不同的输入电压要求，逆变器通常分为低电压(110V、220V、380V等)、中电压(690V、1140V、2300V等)、高电压(3kV、3.3kV、6kV、6.6kV、10kV等)。

由于变频器/逆变器是提供电力的关键部件，因此其运行、性能和可靠性对于保持不间断的供电是至关重要的。本应用说明的重点是TVS二极管，因为即使是在不利的条件下它也可以帮助确保VFD的可靠性和运行的稳定性。

图一变频器/逆变器实物图

图二具有保护元件的典型三相VFD/逆变器拓扑结构

在图二中，橙色部分突出显示了过电流或短路保护的交流线路保险丝。有关保险丝选择的详细信息，请参阅力特（LITTELFUSE）保险丝选择指南。蓝色部分标识的是用于防止由于雷电引起的浪涌或电力线的谐波电压中断而造成损坏的瞬态抑制器。金属氧化物压敏电阻（MOV）由于其钳位性和高功率能力而被广泛应用，所需的MOV额定值将取决于预期的浪涌电流等级和所涉及的交流线路结构。例如，如果交流380V电源连接到图一中，为了满足3KA，8/20μs雷电浪涌要求，三个V20E250P（250V）UltraMOV^®高浪涌电流径向引线压敏电阻可用于线对线（差模）保护，以及单一V20E550P（550V）UltraMOV^®高浪涌电流径向引线压敏电阻可用于线路接地（共模）保护。三个MOV以星形配置连接，并与另一MOV隔开接地，这将提供线对线和线对地的保护。

在选择MOV时，还必须考虑其钳位电压。对于这种情况，当两个V20E250P压敏电阻串联连接以提供差动保护时，它们的钳位电压约为1400V。对于整流二极管、电容器和IGBT(绝缘栅双极晶体管)，电压额定值应大于此值，从而为整个系统提供足够的电压保护。

有时，为整个系统提供电压保护是非常困难的，特别是对于600V或更高的高功率线路电压应用。对于这些情况，Littelfuse提出一种附加（或二次）大功率TVS二极管，它提供精确的低电压钳位能力，为整流二极管、电容器和IGBT提供差动保护。

图三采用TVS二极管的380V三相VFD/逆变器拓扑结构

如图三中的粉红色块所示，可以增加两个AK3-380C TVS二极管，以在最大3kA，8/20μs浪涌电流期间提供差动保护。AK3-380是一种双向高功率的TVS二极管，额定功率为3kA（8/20μs），电压为380V，两个AK3-380C TVS二极管的最大钳位电压为1040V，远低于MOVs。因此，它们为6组IGBT提供了极好的浪涌保护的同时也能保持电路在正常条件下工作。添加这些TVS二极管为设计者在整流二极管和IGBT的选择方面提供了更大的灵活性。

暂时回到图二。红色块显示出了交直流整流二极管。绿色块标识了直流母线过电压的制动斩波器电路。（参阅IGBT制造商的应用说明，以指导选择这些器件的合适型号）。紫色块显示出了IGBT桥DC-AC逆变器用于负载供电。

IGBT保护：

IGBT同时具有功率晶体管和功率MOSFET的优点。它可以工作在高频率情况下，易于驱动和关闭，但它也有一个弱点。通常，需要保护两个部分以实现稳定设计：

•因为栅极是MOS结构，它可以很容易地被静电放电（ESD）、电快速瞬变（EFT）或由米勒效应所引起的过电压所损坏。

•在高功率/大电流应用中，当设备关闭时，IGBT端子C和端子E可能发生高电压涌入。

由于Miller电容器（CGC）的存在，当通过脉冲开关信号驱动IGBT的栅极时，它产生高的过电压，可能会损坏IGBT的栅极。为了在过电压事件期间保护栅极，通常使用双向600W TVS二极管，如图四所示。例如，在一个通常需要+15V偏压的设备上，一个-15V偏置关闭它，一个SMBJ16CA TVS二极管将有助于确保电压低于±20V的最大V_GE。SMBJ16CA TVS二极管的V_BR约为17.8～19.7V，最大值低于20V（正负）。在某些情况下，当IGBT由单极驱动器驱动时，使用单向TVS SMBJ16A TVS二极管代替双向TVS。

图四 IGBT栅极保护

有源钳位技术是在IGBT关断时，将瞬态过电压保持在临界限值以下。如图五所示，有源钳位的标准方法是使用连接在辅助集电极和IGBT栅极之间的TVS二极管。当集电极发射极电压超过TVS二极管击穿电压时，TVS二极管开始导通，并且该电流将增加到IGBT驱动器输出电流的值，这导致栅极发射极电压增加。因此，IGBT仍然保持在有源模式，并且延长了断开过程。随着有源钳位TVS二极管的增加，它将减缓IGBT集电极电流的变化率，这导致有限的电压过冲或减小的IGBT关断过电压δV_CE。因此，串联的TVS二级管对这种过冲电压进行了钳位。这特别适用于V_CE超过1200V的高压IGBTs。

在关断事件中，有源钳位已经被广泛地用于限制IGBT的集电极-发射极电压。当IGBT的集电极发射极电压超过预定阈值时，IGBT部分导通。然后IGBT保持在线性工作中，从而降低集电极电流的下降率，从而降低集电极发射极过电压（见图六，实线的斜率I_C更小，V_GE更长，V_CE的值更小）。

然而，如果在关断事件期间没有在IGBT集电极到栅极处放置TVS二极管，则V_GE的关断将导致集电极和栅极之间的电压突然升高，甚至到更高的电压，这将导致IGBT故障。（参见图六中的虚线）。

图五有源钳位功能

图六涌入电压比较

如图六所示，随着有源钳位电路的增加，V_CE浪涌电压降低。但是设计者如何计算提供这种浪涌保护所需的TVS二极管的数量呢？以下示例可供参考。

如图七所示，IGBT的1300V浪涌电压具有0.5μs的浪涌时间和0.5ms的间隔时间。

图七涌入电压波形

通常，对于1200V IGBT的保护，直流工作电压小于600V，因此是可以选择800V（V_BR-900V）TVS二极管组合的。同时也假设1300V涌入电压在TVS二极管将产生5A的涌入电流。(产生的电流水平也取决于R_GE和R值)

可以用下面的公式粗略估计涌流脉冲功率的水平:

平均P_D = V_BR x I_PP x t_P/T = 900 x 5 x 0.5/500 = 4.5 W

对于这个例子，是可以使用SMCJ TVS二极管的，因为它的热阻抗R_ΘJA为75°C/W，所以如果该电机工作在最大环境温度50°C，那么每个SMCJ的最大允许功率为（150～50）/75＝1.33 W。

需要计算的TVS二极管的数目通过计算4.5／1.33＝3.38pcs来确定，因此至少需要四个TVS二极管串联连接以获得足够的裕度。每个TVS V_BR应该共用900/4＝225V。因此，在这种情况下，建议四个1.5SMC220A TVS二极管。注意，TVS的选择也是基于R和R_GE的实际值。在某些情况下，较低额定电压的TVS二极管，如SMAJ或SMBJ，也可能适用，这要取决于实际的工作条件。

【经验】双向TVS管在IGBT门极驱动电路中的功能分析及选型

在IGBT的门极与发射极之间增加一颗双向TVS管，选择合适的钳位电压，可以实现对门极电压的钳位。推荐采用Littelfuse推出的双向TVS管SMBJ1xCA系列，具有出色的电压钳位能力，峰值脉冲功率可达600W，同时具有快速的响应时间，从0V到击穿电压最小值的响应时间通常小于1ps，可以保证在门极电压VGE升高时迅速反应，有效抑制门极电压的抬升。

【方案】100KW双向储能优选器件方案

描述- 对业内100KW双向储能产品而言，主功率电路多采用了六管IGBT搭建的三相应用拓扑架构。因100KW双向储能选择主功率架构器件时，规格需求通常是1200V/600A（包含裕量），驱动开关频率一般在20kHz以内，考虑到体内二极管散热等因数，功率模块一般会选用三个半桥模块来搭建六管架构。

请问IGBT，VGE最大±20V，驱动电压15V，我是应该选择15V的VC=24.4的，还是VC=20的SMBJ12CA，选型时应该以哪个参数为准呢？

您好，在驱动电压为15V情况下，标称12V的会使得TVS处于触发状态，而标称15V的处于临界值，会因电源供电不稳，导致TVS管触发；如果驱动电压为15V，建议采用标称VR=16V的TVS管，可选用力特的双向TVS 管SMBJ16CA，器件资料：Littelfuse（力特） TVS二极管SMBJ数据手册；设计可参考以下链接：【经验】双向TVS管在IGBT门极驱动电路中的功能分析及选型
