VLT AAF 006 Advanced Active Filters

Danfoss Advanced Active Filters can compensate for individual VLT drives or can be installed as a compact stand-alone solution at a common point of coupling, compensating for several loads simultaneously. The extensive re-use of proven VLT components and the modular construction ensures a high reliability and at the same time offers high energy efficiency, back channel cooling and high enclosure grades without size increase.

Consequently the filter ensures optimal harmonic suppression independent of the number of loads and their individual load profile. In addition the active filter corrects the power factor and balances the phase load providing an optimal energy utilization. This improves the system efficiency and increases the grid robustness to avoid downtime. The VLT Advanced Active Filter is easily controlled via the user-friendly LCP, sharing design and programming structure with the VLT drives series.

VLT Advanced Harmonic Filter AHF 005 & AHF 010

The Danfoss AHF 005 and AHF 010 are advanced harmonic filters, not to be compared with traditional harmonic trap filters. The Danfoss harmonic filters have been specially designed to match the Danfoss frequency converters. By connecting the Danfoss harmonic filters AHF 005 or AHF 010 in front of a Danfoss frequency converter, the harmonic current distortion generated back to the mains is reduced to a minimum. AHF 010 reduces the harmonic current to less than 10% and the AHF 005 reduces the harmonic current to less than 5%.

Danfoss has created a PC based program MCT31 for calculation of harmonics with different principles for suppression. It can calculate the harmonics for danfoss frequency converters depending on actual system (transformer, cables, other loads, etc.) Danfoss harmonic filters perform excellently. The figures show the reduction of each of the sub-harmonic orders at full load.

VLT dU/dt Filter

dU/dt filters reduce the dU/dt values on the motor terminal phase-to-phase voltage - an issue that is important for short motor cables. dU/dt filters are diff erential-mode filters which reduce motor terminal phase-to-phase peak voltage spikes and reduce the rise time to a level that lowers the stress on the insulation of motor windings.

Compared to sine-wave filters, the dU/dt filters have a cut-off frequency above the switching frequency. The voltage at the motor terminals is still PWM pulse shaped, but the rise time and Upeak are reduced. They are smaller, weigh less and have a lower price compared to sine-wave filters. Furthermore, because of the smaller inductance and capacitance, the dU/dt filters introduce a negligible reactance between inverter and motor and are therefore suitable for high dynamic applications.

VLT Sine-Wave Filter

Sine-wave output filters are low-pass filters that suppress the switching frequency component from the drive and smooth out the phase-to-phase output voltage of the drive to become sinusoidal. This reduces the motor insulation stress and bearing currents. The sinusoidal motor terminal voltage from the sine-wave filter furthermore has the advantage of suppressing any bearing currents in the motor. This reduces the risk of flashover in the motor bearings and thereby also contributes to extended motor lifetime and increased service intervals.

By supplying the motor with a sinusoidal voltage waveform, the switching acoustic noise from the motor is also eliminated. The sinusoidal voltage supply to the motor reduces hysteresis thermal losses in the motor. Since the motor insulation lifetime is dependent on the motor temperature, the sine-wave filter prolongs the lifetime of the motor.
