What is sulfation of batteries?
Sulfation is the formation or deposit of lead sulfate on thesurface and in the pores of the active material of the batteries'lead plates. If the sulfation becomes excessive and forms largecrystals on the plates, the battery will not operate efficientlyand may not work at all. Common causes of battery sulfation arestanding a long time in a discharged condition, operating atexcessive temperatures, and prolonged under or over charging.
What are some of the major types of lead acid batteries?
Batteries are divided in two ways, by application (what they areused for) and construction (how they are built). The majorapplications are automotive, marine, and deep-cycle. Deep-cycleincludes solar electric (PV), backup power, and RV and boat "house"batteries. The major construction types are flooded (wet), gelled,and AGM (Absorbed Glass Mat). AGM batteries are also sometimescalled "starved electrolyte" or "dry", because the fiberglass matis only 95% saturated with Sulfuric acid and there is no excessliquid. Flooded may be standard, with removable caps, or theso-called "maintenance free" (that means they are designed to dieone week after the warranty runs out). All gelled are sealed and afew are "valve regulated", which means that a tiny valve keeps aslight positive pressure. Nearly all AGM batteries are sealed valveregulated (commonly referred to as "VRLA" - Valve RegulatedLead-Acid). Most valve regulated are under some pressure - 1 to 4psi at sea level.
什么是电池的硫酸化？硫酸化是指在电池铅板的活性物质表面和孔隙中形成或沉积硫酸铅。如果硫酸化变成了在板上形成大的晶体，电池将不能有效地工作，甚至可能根本无法工作。电池硫酸化的常见原因是长期处于放电状态，在过高的温度下工作，在充电下或充电过久。铅酸蓄电池的几种主要类型是什么？电池分为两种方式，根据应用(它们是什么)。(用于)和构造(它们是如何建造的)。主要应用是汽车，船舶，和深循环.深层循环包括太阳能(Pv)、备用电源、rv和船屋电池。。主要建筑类型有水淹(湿)、胶凝和AGM(吸收玻璃垫)。agm电池有时也被称为“饥饿电解液”或“干电池”，因为玻璃纤维垫只有95%s。在硫酸下饱和，没有多余的液体。淹水可能是标准的，带有可移动的盖子，或者所谓的“免维护”(这意味着它们的设计是在战后一周内死去的)。放屁)。所有的胶都是密封的，少数是“阀门调节”的，这意味着一个微小的阀门保持一个轻微的正压力。几乎所有的AGM电池都是密封阀调节的(通常是重新调整)。推测为“阀控铅酸”。大多数阀门是在一定的压力下调节的-1到4 psi在海平面。
当模块化UPS系统中的某一个功率模块发生故障，那么故障模块就需要及时退出系统，以减少该故障功率模块对模块化UPS系统的影响，进而保证输出电压稳定。
在模块化UPS的研发过程中，会进行各种单一故障测试，以保障UPS功率模块在发生单一故障时，才能保证模块化UPS系统的稳定运行。其中逆变IGBT短路单一故障对模块化UPS系统的输出稳定性提出了较大的挑战。
IGBT短路检测功能
针对上述问题，逆变电源加入了独有的IGBT短路检测功能电路，结合软件算法，能快速检测出IGBT短路状态，主动控制功率模块退出系统，从而保证模块化UPS系统在单一功率模块逆变IGBT短路故障发生时，能维持逆变供电，并且不需要切换到旁路供电模式，且间断时间小于10ms。
