Product Description
Active harmonic filters (AHFs/APF) are typically stand-alone devices that reduce the high levels of harmonics produced by energy efficient non-linear loads.They work by injecting harmonics into the electrical system in equal and opposite measure to the existing system harmonics.As previously mentioned, harmonic filters are used to eliminate harmonic distortion caused by excess currents in and out of appliances. It can prevent large quantities of harmonics from causing damage to equipment, downtime of operation, and preventing an increase in operating costs.
The Active power filter monitors the load current real-time through the external current transformer CT, and extracts the harmonic component of the load current through the internal DSP computing, then sends it through the PWM signal to the internal IGBT, the inverter produces a current equal to the load harmonic and opposite to the harmonic direction and injects the current into the grid to compensate the harmonic current realizing the function of harmonic control.System parameters | |
