UPFC功率模块状态检测和评估方法
|
摘要
设计统一潮流控制器(UPFC)功率模块测试平台,在不同绝缘栅双极型晶体管(IGBT)结温条件下通过实验对功率模块关断感应电压VeE进行采样,再从感应电压中提取关断延迟时间toff和最大关断感应电压负峰值VeE_NP。实验结果表明:当集电极-发射极电压VCE与集电极电流IC确定不变时,随着IGBT功率模块结温的增大,toff变大,最大关断感应电压负峰值VeE_NP的绝对值逐渐变小。最后得出基于最大关断感应电压负峰值VeE_NP和关断延迟时间toff的UPFC功率模块状态检测与评估方法。
Through designing the UPFC power module test platform,the power module switching induction voltage VeEwas sampled under different IGBT temperature conditions,then the turn-off delay time toffand the maximum turn-off induction voltage VeE_NPwere extracted from the inductive voltage. The experimental results show that,when the collector and emitter voltage VCEand collector current ICare fixed and immovable,the toff of the IGBT power module increases gradually,the toffbecomes larger gradually,and the absolute value of the maximum turn-off inductive voltage VeE_NPgradually becomes smaller. Finally,the state detection and evaluation method of UPFC power module based on the maximum turn-off induction voltage VeE_NPand the turn-off delay time toffwas obtained.
