今天我们就来说一说有关IGBT的一项比较重要的测试——双脉冲测试(Double Pulse Test) 当然,网上可以找到很多关于IGBT双脉冲测试的资料,不同厂家的都有,基本的测试过程都是差不多的,其目的也是一致的(为了验证IGBT的性能是否过关)。双脉冲测试的必要性在现在的行业中是显而易见的,其决定了对应的IGBT是否会被选用,...
功率电子双脉冲Double Pulse Test方案 来源:深圳市优测科技有限公司2024年08月12日 17:48 功率电子双脉冲测试方案 在功率电子学中,开关器件的理想状态是“开”和“关”,但是在实际应用中,由于寄生电容 / 电阻(体二极管)对于功率器件的影响,开关过程中会有功耗产生。为了评估开关器件的性能,工程师需要测量各种...
In addition, if the current pulse is long, then the chip temperature can increase by more than a few °C, again affecting the switching performance.• The inductor should be mounted well away from the test setup to prevent EMI interference or magnetic field coupling into any gate drive ...
The development of a power electronic assembly requires several steps. One of these involves the dynamic characterization of the switching behavior of the power semiconductors. For this purpose, a double-pulse test setup is used which includes: a capacitive energy storage device, also known as a d...
while doing the double pulse test, I found that the Ids current oscillates badly during switching, which makes it impossible to estimate the switching loss and other parameters. May I ask what could be the cause of this? The measured waveforms are shown below, the blue Vm channel is the ...
4 The double pulse test application on the AFG31000 does not have two channel functionality, so a low/high side double pulse test requires a manual test setup. Tektronix is ISO 14001:2015 and ISO 9001:2015 certified by DEKRA. 61W-73888-5About...
Figure 1: Basic Double Pulse Test Setup We’ve added additional detail to the diagram from April’s article to highlight several important considerations. All measurement instrumentation is referenced to earth ground. Oscilloscope inputs are single-ended when using conventional probes, with ...
功率半导体Double Pulse Test方法 实施双脉冲测试,不仅能精准测量功率设备的开关特性和损耗,而且能进一步优化电力转换过程。通过示波器上的WBG-DPT应用软件,可以通过自动化测试流程,显著提高测试效率和结果的可靠性。本篇将详细介绍WBG-DPT的优势,如缩短测试时间、提高测量的重复性,以及按照JEDEC/IEC标准或自定义参数进行...
The gate of the device under test (DUT) is driven by the AFG31000 Arbitrary/Function Generator.Figure 2shows a high-current power supply driving VDDwhich is a typcal double pulse testing setup. However, for this low-current example, a Keithley triple output power supply was used to power ...
