(Summary description)1. Incoming line reactor
Also known as input reactor or power supply coordination reactor, it can limit the current impact caused by grid voltage mutation and operating overvoltage, and effectively protect the inverter; it can not only prevent the interference from the grid, but also reduce the harmonic generated by the rectifier unit. The wave current pollutes the power grid and improves its power factor.

Information
1. Incoming line reactor
Also known as input reactor or power supply coordination reactor, it can limit the current impact caused by grid voltage mutation and operating overvoltage, and effectively protect the inverter; it can not only prevent the interference from the grid, but also reduce the harmonic generated by the rectifier unit. The wave current pollutes the power grid and improves its power factor.
2. DC reactor
The DC reactor is connected between the DC rectification link and the inverter link of the frequency conversion system. The DC reactor can make the inverter link run more stably and improve the power factor of the inverter. In a frequency conversion system with a DC link, connecting a DC reactor after the rectifier can effectively improve the power factor, and the power factor can be increased to 0.95 with proper coordination. In addition, the DC reactor can make the inverter run stably and limit the short circuit current.
