电流尖峰 meaning in English

current spike

Thirdly , the snubbers are designed to compress the switching voltage transient . when igbt is abruptly turned off , trapped energy in the circuit stray inductance is dissipated in igbt , causing a voltage overshoot and damaging igbt . this paper analyzes the principle of the snubber and discusses the impact of the parameters of the snubber on voltage overshoot
针对igbt工作过程中出现的电压尖峰、电流尖峰和大的开关损耗问题，本文首先从理论上详细分析了igbt逆变桥缓冲电路的工作原理，推导出缓冲电路各元件的参数计算公式，讨论了缓冲电路各元件参数对关断电压波形的影响并进行了仿真分析。
