Working Principle

The MUBW25-12T7 is an IGBT module that works based on the principle of insulated gate bipolar technology. IGBTs use an electrically insulated gate to control the flow of current. This gate allows current to flow if it is switched on, but prevents current from flowing when the gate is switched off. When the gate is switched on, the IGBT allows current to flow, which is then controlled by the gate voltage. The gate voltage is essentially the power source that switches the IGBT on and off. If the gate voltage is increased, the IGBT will allow more current to flow, while a decrease in the voltage will cause the IGBT to switch off. This makes the IGBT a highly efficient and reliable switching solution for applications such as motor drives and power supplies.

Conclusion

The MUBW25-12T7 is an industrial-grade IGBT module designed for a wide range of applications, including motor drives, power supplies, motor starters and general-purpose inverters. It offers high power efficiency and reliable operation in harsh environments. The working principle of this IGBT module is based on the insulated gate bipolar technology, which uses an electrically insulated gate to control the flow of current. This makes it a highly efficient and reliable switching solution for applications that demand high power efficiency.
