    What are the application fields of fast recovery diode FRD devices?

    Fast recovery diodes, namely power semiconductor devices, are the bridge between weak current control and strong current operation, between information technology and advanced manufacturing, and are an important foundation of the national economy. With the increasingly urgent demand for energy saving and emission reduction in countries all over the world, power semiconductor devices have moved from traditional industrial control and 4C (communication, computer, consumer electronics and automobile) to new energy, rail transit, smart grid, frequency conversion Home appliances and many other industries.

    How to quickly check the fault of the IGBT module?

    Due to the unbalanced output voltage of the frequency converter (VFD), the motor shakes and the speed is unstable. In general, it is difficult to determine which drive is at fault without experience. At this time, the 2hz of the VFD can be started, and the voltage values of p-u, p-v, p-w and u-n, v-n and w-n can be measured respectively with the DC voltage range of the multimeter. These six voltages will be different at this time, and the higher voltage will be different. The following is a simple measurement method for IGBT modules.
