摘要
为了探究换流器件IGBT的开关特性,设计一套用于中压IGBT动态特性测试的实验平台。该测试平台采用双脉冲测试的方法,以计算机为核心,通过充电电容提供母线电压,通过DSP提供双脉冲,以高效能示波器实现数据的采集和存储。借助实验所得的电压、电流波形曲线及存储的数据,可估算IGBT的开关特性参数和损耗。通过对FF50R12RT4(1200V/50AIGBT)的开关特性的测量,从而验证了该平台的实用性。
In order to test the switching characterization of IGBT in value state,an off-line insulated gate bipolar transistor （IGBT） switching characteristics measurement system was designed. The control of test platform is based on computer, the bus voltage is provided by the charging capacitor, the double pulse used to test is controlled by DSP, and the high-performance oscilloscope is adopted for the data acquisition and storage, computer is used for post-data processing. With the waveforms of voltage and current during switching transients and the data restored, the switching characteristics parameters and loss can be estimated. The switching characteristics of FFSOR12RT4 （1200V/50A IGBT） were tested, so as to verify the practicability of the platform.
