【应用】适用于交流电源线应用的高功率半导体撬棒保护器
电源输入线的风险和保护
交流电源线干扰是许多设备发生故障的主要原因。这种损坏可能会像偶尔发生的数据丢失一样难以捉摸,或者像电源,LED照明,工业系统和消费设备(如烤箱或冰箱和电视机)的破坏一样引人注目。
电源线干扰有许多名称,如瞬变、浪涌、尖峰、毛刺等。但是,无论具体名称如何,了解其特性和各种可用保护元件的操作对设计有效的保护电路都是必需的。
这些电源输入线有一些比较流行的保护组件。最常见的过电压保护元件是MOV(金属氧化物压敏电阻),高功率TVS(瞬态电压抑制)二极管和GDT(气体放电管)。在本文将讨论一种新颖的创新方法,使用称为SIDMAT®的保护晶闸管硅撬棒组件用于交流电源线的主要过电压保护解决方案。
浪涌保护
浪涌保护器件可分为两种基本类型:撬棒型器件,如GDT和保护晶闸管型SIDACtor组件和钳位型组件,如TVS二极管,MOV等。
钳位型组件具有更快的响应时间,但其电流处理能力有限,因为瞬态能量必须由钳位组件耗散。此外,钳位型元件两端的电压降随传导电流的增加而增加。因此,较高的钳位电压阈值分量将具有较低的峰值电流能力。(特定系列中的所有组件的额定功率保持不变,但由于功率是电压和电流的乘积,因此增加的电压需要降低电流)。
撬棒型元件可以处理更高的浪涌电流,因为在导通状态下,元件两端的电压非常低。这些撬棍组件充当“近短路值”路径,将暂态能量从受保护设备中分流出去。而这种低导通电压将进一步降低受保护电路的过电压。
交流电源线路保护中的SIDACtor组件
由于SIDACtor组件的特性是一个撬棒保护及其与交流电源的兼容性,因此可能会产生问题。本文将回顾为交流电源线路保护选择SIDACtor组件的设计参数。请注意,关于SIDACtor组件使用的讨论仅限于交流电源线; 它与大电流直流电源端口不兼容。 对于AC信号,SIDACtor组件将在每个半周的零交叉处的AC端口上复位。但是,对于大电流直流电源线,如果可用短路电流高于其保持电流参数,则SIDACtor组件不会复位。
LITTELFUSE Pxxx0FN和Pxxx0ME系列SIDACtor组件
Littelfuse Pxxx0FN和Pxxx0ME系列高能量SIDACtor组件具有撬棒特性,可提供低于传统GDT电弧电压的低导通电压值,并且其电压门限比MOV的钳位电压低得多。与钳位硅TVS二极管相比,Pxxx0FN和Pxxx0ME SIDACtor器件可处理更高的浪涌电流,因为其导通电压非常低。与GDT,MOV或TVS组件相比,它还为高dv/dt或高di/dt事件提供更低的过冲特性。
Pxxx0FN和Pxxx0ME系列具有58v至450v的组件工作电压(VDRM)(也称为断态电压)。参考IPP浪涌电流和ITSM表格,Pxxx0ME提供5000A 8/20 IPP(峰值脉冲电流额定值)和最小400A ITSM用于50/60Hz AC单周期正弦波浪涌事件,Pxxx0FN提供3000A 8/20 IPP和用于50/60Hz AC单周期正弦波浪涌事件的最小300A ITSM。

Pxxx0FN和Pxxx0ME是传统GDT的改进解决方案,其提供:
•低通状态电压条件下长期工作的低热量积累
•在高dv/dt事件期间降低过冲
•没有磨损机制
•在不牺牲过冲特性的情况下,更接近于某些国家交流电源线的隔离值选择(较低电压GDT使用不同气体/较高电压版本的较低气压,因此导致特性变慢和过冲更高)

Littelfuse Pxxx0ME系列SIDACtor组件
图二显示了一个SIDACtor组件P3800MEL,与电源线保险丝一起使用,然后串联一个过电流保险丝保护器。在正常工作条件下,SIDACtor组件和系列保险丝不会对电源线产生干扰和透明工作。当交流电压或浪涌感应电压超过P3800MEL组件的VDRM时,它开始切换到低电阻状态。电源线熔断器用于保护SIDACtor组件,使其在重复正弦交流电源事件中不超过电流ITSM值。
这种组合将为该电源端口提供协调的过流和过压保护解决方案。图二(右)中为设计人员提供了一个专用于SIDACtor的增强型过电流保护的选项。这种与SIDACtor组件相连的系列保险丝可以保护SIDACtor组件免受过载或过应力的影响。该解决方案的主要区别在于电源线保险丝必须按照SIDACtor+系列保险丝组合。SIDACtor+系列保险丝可为电源保险丝和后续电源电路提供浪涌保护,同时电源保险丝可保护交流线路电流和电源电路。如果电源电路需要敏感的过电保护,这一点显得尤为重要,因为此电源保险丝不需要考虑提供高浪涌能力。请注意,上述保护拓扑结构是一些示例。实际的保护方案将需要在实际环境中进行测试和验证。
图三 有不同的熔丝拓扑选项以及SIDACtor的演示板
图四展示了SIDACtor组件对3kA 8/20浪涌的响应(没有连接到交流电源)。橙色线显示3kA 在8/20的浪涌波形,蓝色线显示SIDACtor组件响应曲线。这个P3800MEL在撬棒之前的初始峰值为272V,并将电压限制在30V以内。
图四 SIDACtor组件对3kA 8/20浪涌的响应
图五,当SIDACtor组件响应交流电压线上的3kA浪涌时,施加于SIDACtor组件的交流电流(278A)有很大的跟随。由于P3800MEL ITSM额定值为最小400A(50/60 Hz,单周交流电流额定值),可以安全地处理,因此该半周期高交流电流不会损害SIDACtor组件。该限制动作是线路阻抗和/或电源电流额定值的函数。
图五 P3800MEL触发后的交流电流跟随
将SIDACtor组件与其他MOV夹紧装置一起使用
Littelfuse Pxxx0FN和Pxxx0ME系列还可以与MOV串联,为较高的钳位电压损坏的电路创建低钳位保护。
MOV和SIDACtor组件组合的导通阈值必须高于稳态交流线路电压,但一旦激活该组合,使用撬棒组件的钳位电压将低于MOV自身可提供的钳位电压。
图六展示了一个较低的工作电压SIDACtor组件P2300MEL(DC 180V),与一个Littelfuse MOV V20E130P(AC 130V)串联连接,后面是一个保险丝。这个完整的电路为交流线路提供过流和过压保护。
图六 P2300MEL+V20E130P低钳位解决方案
图七展示了SIDACtor组件+MOV组合在3kA 8/20浪涌事件期间产生的最大钳位电压为425V,比仅低于导通状态电压30v的SIDACtor组件高。较高的钳位电压是由于V20E130P MOV钳位电压与P2300MEL SIDACtor器件一起加在状态电压上产生的,因此钳位电压大于30V,如上例所示。但是,如果单独使用MOV,对于这条240v交流电线路,所需的MOV将是V20E275P,钳位电压将高达900V以上,这可能会损坏下面的电子设备。仅SIDACtor组件,SIDACtor组件+MOV组件和MOV组件解决方案的组合之间的钳位电压差异显示出三种截然不同的保护解决方案结果。
图七 P2300MEL+V20E130P的3kA 8/20浪涌响应
在图八中,在3kA 8/20浪涌触发SIDACtor组件+ MOV组合后,交流跟随电流测量值为43.2A。 与独立的SIDACtor解决方案相比,添加MOV可以降低AC跟随电流。另一方面,SIDACtor+MOV组合还可以提供比独立MOV解决方案更低的泄漏电流,从而提高MOV的使用寿命。因此,SIDACtor可以为交流线路电源保护中的传统MOV解决方案带来互利。对于一些敏感的设计或合规性目的,应该在生产线中增加一个电流中断设备(熔断器组件)以符合安全列表要求。
图八 交流电流在P2300MEL+V20E130P以3kA浪涌(240V AC耦合)触发后继续运行
在图九中,SIDACtor+MOV组合设备在逆变器驱动电路的输入线一侧形成了过压保护解决方案。它旨在允许交流电压运行时进入功率开关(如IGBT/IGBT模块/MOSFET),同时钳位/吸收这些不需要的瞬态噪声和干扰。它可以分别使用1个或3个SIDACtor+MOV组件设计为单相或三相模式。这种保护拓扑广泛应用于EV电动车辆和HEV混合动力电动车辆应用中。
图九 EV/HEV直流充电器浪涌保护3相交流电源线(左)
交流电源线逆变器浪涌保护(右)
如图十所示,SIDActor+MOV在光伏电池输出端被差分连接(L-N),以避免任何不需要的瞬态电压。太阳能电池板产生的电流由高压开关MOSFET调节到所需的交流电流。实际的SIDACtor和MOV组合取决于PV转换器设计的浪涌和保护要求。
图十 光伏光电转换器保护
保险丝额定浪涌电流和交流跟随电流值的计算
需要保险丝的中断额定值大于3kA 8/20浪涌事件和交流跟随电流的总和,但低于SIDACtor组件的ITSM额定值。这样可以防止保险丝引起不良开口,但可以适当打开以保护SIDACtor组件。保险丝中断值可以通过其I2t值进行最佳估计。
这里举例说明如何在组合MOV+SIDACtor组件电路的3kA 8/20事件期间计算正确熔断器选择的I2t总值。
对于浪涌:3kA 8/20浪涌电流I2t约为1/2x Ipeak x Ipeak x t = 1/2 x 3000 x 3000 x 20 x 10-6 = 90A2s。
对于交流电:半周期交流电跟随电流I2t将为1/2x Ipeak x Ipeak x t = 1/2 x 43 x 43 x 0.01 = 9.245A2s。
总I2t将为90 + 9.245 = 99.245 A2s。
图十一 保险丝I2t降额曲线
请注意,需要考虑预期的应用环境温度条件和预期脉冲数量的保险丝降额。例如,如果熔断器需要100,000个脉冲,则应考虑0.22倍(请参考熔断器降额曲线,如图十一所示)。请注意,对于浪涌保护应用,通常需要考虑几十个脉冲,因此0.48降额因子就足够了。
如上所述,熔丝I2t需要大于99.245/0.22 = 451A2S。半周期交流SIDACtor组件的I2t值为1/2 x 400 x 400 x 0.01 =800A2S。(400A是P3800MEL的最大ITSM)。显然,降额I2t(451 A2S)小于半周期SIDACtor组件I2t(800 A2S),以确保熔断器在ITSM SIDACtor额定值超出前打开。
对于MOV,通常我们会根据交流电流能量来计算其MOV参数是否足够。在这种情况下,通过MOV V20E130P的总电流能量为3kA 8/20加上43A半周期交流电流。所以总能量是0.71x250x3000x20x10-6 + 0.71x250x43x0.007 = 10.65 + 53.43 = 64.08J。该值小于V20E130P 100J数据表规格。
因此,所选择的保险丝的I2t额定值将大于3kA 8/20浪涌电流,和交流跟随电流能量,从而确保OVP解决方案按照设计运行时不会导致开路。
然后,具有AC 250V额定值和I2t值为451的保险丝是保护SIDACtor组件+MOV组件的最佳选择,同时保持正常操作,但为SIDACtor组件+MOV组件提供保护。
几种满足451 A2S要求的Littelfuse保险丝类型
如图十二所示,Littelfuse还提供具有集成热保护熔丝的TMOV产品,以缩短电路设计周期。
图十二 集成热保护熔丝的TMOV产品
图十三是针对CATV 90伏正弦波供电方案的典型浪涌保护解决方案。
图十三 有线电视放大器中的SIDACtor组件
在图十三中,使用了P1900MEL,因为峰值关闭状态(VDRM = 155v)电压远高于CATV电源的峰值电压(90x1.414 = 127v)。请注意所需的补偿电感电路,以防止关闭状态的SIDACtor元件电容干扰CATV RF信号。
结论:
Pxxx0ME SIDACtor组件非常适用于交流电源线路保护。它具有低导通状态撬棒阈值,快速导通特性,低过冲,高浪涌电流,精确的工作电压值,并且不会因其浪涌额定值内的重复激活而磨损。在SIDACtor组件之前使用合适的保险丝/过电流元件,它可以为交流电源线提供出色的保护解决方案。再次注意,这只适用于交流电源线上的短期浪涌,而不适用于大电流直流电源线,除非直流电流限制在低于保持电流参数的SIDACtor元件的电平或直流电源识别短路负载条件并自动关闭。
