Fuji Electric looks forward to carrying out in-depth communication with you according to the publicity and education content of this seminar, so that everyone can have a good understanding of Fuji Electric.

In order to meet the market demand for miniaturization and high reliability of IGBT modules, Fuji Electric has developed RC-IGBTs (Reverse-Conducting IGBTs), which combine IGBTs and FWDs as single chips. The combination of the 7th generation "X series" chip technology and packaging technology with RC-IGBT technology makes the 7th generation ...

When we are repairing the inverter, we often encounter the inverter that triggers the overvoltage protection, at this time, I often wonder, can the overvoltage protection measures be different because of the overvoltage? (1) For the interrupting overvoltage of the phase-shifting transformer, the resistor-capacitance absorption network and oxygen ...

Fujifilm servo motor has many precautions in use, and the following is a brief introduction 　　Fujifilm servo motors can be used in places where water or oil droplets are attacked, but they are not completely waterproof or oil-resistant. Therefore, servo motors should not be placed or used in water or oil environments. If you serve ...

In order to achieve a more efficient and controllable operation of the motor, and avoid the waste of power of the motor drive system, the inverter came into being. However, due to the variety of motor load types, the functional requirements for the equipped inverter are also different, so how to choose the right transformer for the motor...

Instrumentation spreads through all sectors of the national economy and penetrates into all corners of people's lives. For example, in the machinery manufacturing industry, the static and dynamic performance of the product is tested, the processing process is controlled and monitored, and the fault diagnosis in the operation of the equipment is diagnosed. In the electric power, chemical, petroleum industries, ...

After the inverter runs uninterrupted for a long time, the high temperature generated inside has serious hidden dangers to the operation of the inverter, especially in summer. The ultimate operating temperature of the inverter inside the inverter is generally 125 °C, and the temperature of the inverter inverter module and IGBT can sometimes reach 110 °C.
