Large impulses of electrical power are required by various civil, industrial, and military applications; these include lasers, fusion power generators, radar systems, lightning simulators, pulse welders, and x-ray machines as well as many others. Providing thedesired electric pulses is a challenge as the common power generation methods cannot supply such rapidly spiking impulses (especially in systems isolated away from the electrical grid). In practice, the most common method for generating the pulses is to store electrical energy over a long period of time, and then release all of the stored energy in a very short period of time. The electrical storage used is usually specialist ceramic capacitors as most other types of capacitors and batteries will be damaged bylarge and rapidly transient voltages and currents.

各种民用、工业和军事应用都需要大脉冲的电力;这些应用包括激光器、聚变发电机、雷达系统、闪电模拟器、脉冲焊机和X光机以及许多其他应用。提供所需的电脉冲是一个挑战，因为普通的发电方法无法提供如此快速的尖峰脉冲（特别是在与电网隔离的系统中）。在实践中，用于产生脉冲的最常见的方法是在长时间段内存储电能，然后在非常短的时间段内释放所有存储的能量。所用的电存储通常是专业陶瓷电容器，因为大多数其他类型的电容器和电池会被大而快速的瞬态电压和电流损坏。
