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.

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.

IGBT Module Static Parameters

VCES: Collector-Emitter Voltage Of The IGBT The highest allowable off-state collector-emitter voltage in the gate-emitter short circuit condition within the usable junction temperature range. In the manual, VCES is specified at a junction temperature of 25°C, and VCES will decrease as the junction temperature decreases. The relationship between the reduction range and the temperature change can be approximately described by the following formula: .
