Product application

 

The harmonic filter is designed to substantially eliminate the harmonic current distortion caused by pulse rectifier, the harmonic flter is a passive series of inductor capacitor connecting with low-pass filtering wave, which is used to remove the low frequency harmonic wave with special grade 5,7,11,13 generated by the three-phase full wave frequency inverter load. lt does not require a single regulation or phase shift according to the single adjustment or different harmonic source. The highest harmonic content can be controlled within 8%.The harmonic filter is usually used in three-phase electronic devices, such as the speed adjustable DC motor driver, welding machine, battery charger, uninterruptible power supply (UPS), induction heating equipment, servo driver and other electronic equipment. Being different from the other harmonic filters technology, the harmonic filter can guarantee the filtering results. In AC frequency conversion and variable torque drive application (fan and water pump), the harmonic flter can definitely satisfy that the maximum THIlD (total harmonic current distortion) under the full load is not higher than the guaranteed percentage.In addition, the harmonic filter will not cause the resonance of the power system or absorb the harmonic wave from other nonlinear loads.

Output Reactor

It is installed at the output end of the inverter, which is used to limit the capacitive charging current of the inverter and the motor connecting cable, and inactivate the voltage rise rate of PWM wave output by the inverter. When the length of motor cable exceeds a certain value, it is recommended to insert a motor reactor between the inverter and the motor, which is used to compensate the recharging current of capacitor in case of the long wires. The maximum length depends on the rated value of the frequency converter and the type of the motor cable.
