Description of this 315KW to 500KW Economical inverter with reactor and low price frequency inverter from Powtech
 
In order to reduce the interference of the inverter to other equipment and the power grid, and to prevent the interference from other interference sources of the power grid to the inverter, it is necessary to add anti-interference devices such as filters and reactors at the input and output ends of the inverter. It is convenient for users to use filters, reactors, braking resistors and braking units with different specifications of inverters.
1. AC reactor
It is connected in series on the input side of the power supply and the inverter to suppress the high-order harmonics of the input current, reduce the impact of the power surge on the inverter, improve the imbalance of the three-phase power supply, and improve the power factor of the input power supply (up to 0.75- 0.85). It is recommended to use an input AC reactor under the following conditions:
The ratio of the power supply capacity to the inverter capacity used by the inverter is 101 or more;
A thyristor device or a power factor compensation device with switch control is connected to the same power source;
The voltage imbalance of the three-phase power supply is large (≥3%);
Due to the large volume and high cost of the AC reactor, the AC reactor is considered when the inverter power is >30kW.
2. DC reactor
The DC reactor is connected in series in the DC intermediate link bus (between terminals P1 and P+). Mainly to reduce the high-order harmonic components of the input current, improve the power factor of the input power supply (to increase to 0.95). This reactor can be used simultaneously with an AC reactor, and configuration is only considered when the inverter power is >30kW.
