About Temperature Measurement of Internal IGBT Modules with NTC Thermistor


Exsense company manufature NTC thermistor chip for 10 years. And the feature is high stability and high accuracy. It application in IGBT modules.

Let get know more about the temperature measurement of IGBT modules with NTC chip.

One of the most important parameters of power electronics is the chip temperature. However, a sensor that is mounted on a chip and even as part of thechip to measurement temprature directly.This will reduce the chip's ability to pass through an effective area.

Another feasible way is to measure chip temperature through a thermal model and on the basis of the basic temperature as measured data began to calculate the junction temperature, in many electric power module, thermistors also known as the NTC to be integrated internally as atemperature sensor, in order to convenient accurate precision temperature device design.

NTC according to near the silicon chip, in order to get a more tightly coupled heat, according to different modules, the NTC or with the silicon chip installed on the same piece of DCB, and according to the single substrate.
