Detailed Explanation of IGBT Module Parameters - Thermal Resistance

The power dissipation and rated current of the IGBT module are meaningless regardless of the temperature and thermal resistance of the IGBT module. Therefore, in order to compare the performance of different power devices, it is necessary to analyze their thermal characteristics. The heat generated by the power loss of the IGBT module will increase the junction temperature inside the device, thereby reducing the performance of the device and IGBT converter and shortening its life. It is very important to dissipate the heat generated from the chip junction to reduce the junction temperature. The transient thermal impedance Zthjc(t) describes the heat dissipation ability of the device. The thermal resistance Rth is defined as the value of the junction temperature rise relative to the temperature of the external specified point caused by the unit power consumption when the silicon chip consumes power and reaches thermal balance. It is a key factor to measure the heat dissipation capability of the IGBT.

Safe operation of IGBT module/IPM

When the IGBT is turned off, the operating range of the VCE-IC that works safely is called the reverse bias safe operating area (RBSOA: Reverse Bias SafeOperation Area), also known as the switch safe operating area, which refers to the maximum allowable instantaneous voltage during repeated shutdown operation current.

The Main Components Of UPS Power Supply

In terms of structure, UPS power supply can be mainly composed of several main parts such as rectifier, inverter, bypass switch, battery, etc. The working principle of each part is different. This article will analyze the composition of UPS power supply and each component in detail Analysis of the principle function.

2023 World Power Supply Industry Expo Grand Opening

2023 World Power Supply Industry Expo Grand Opening Take advantage of the "dual carbon" trend to welcome new energy business opportunities. Anchoring the current steady growth of the power supply market environment, on August 8, the 2023 World Power Supply Industry Expo (formerly the 13th Asia-Pacific International Power Supply Products and Technology Exhibition) hosted by Guangdong Hongwei International Exhibition Group was held at the Guangzhou Canton Fair. The grand opening was held on the third floor of Area B of the pavilion. With "electricity" as the source of business, we joined hands with merchants in the power supply industry at home and abroad to draw a new blueprint for the power supply industry.
