PQE hMF – hybrid Modular Filter
modular and flexible
The power quality toolbox for the assessment of active and passive filters
Our product portfolio for optimizing power quality
Thanks to the fully modular design of our PQE hMF filters, suitable filter solutions can be set up quickly and easily for all typical mains disturbances:
Harmonics – Interharmonics – Supraharmonics – Clock frequencies – Resonances – Reactive power – Unbalance – Transients – Common mode disturbances – Differential mode disturbances…
Depending on the application, a hybrid Modular Filter PQE hMF can consist of several identical or also different filter modules. The standard filter cabinet hMF-CAB is available in widths of 400, 600 and 800 mm with a height of 2000 mm. Protection classes from IP20 to IP54 and water cooling enable a wide range of applications.

hMF CAB Filter module cabinet
The PQE hMF hybrid modular active filter is a ready-to-connect solution for compensation of mains perturbations in commercial and industrial grids. It is modularly constructed from individual filter modules and can be easily expanded if the performance is increased or requirements change.
As with all common active filters on the market, the filter control operates current-controlled. Depending on the control principle, current transformers must be installed either in the supply of the distribution (closed loop) or in the output of the load to be compensated (open loop). As a special feature, the PQE hMF can also operate voltage-controlled on its own. When operating with “Voltage Control”, no current transformers need to be installed.
For each task, active and passive filter modules can be combined with the hybrid filter system.
hMF CAB-UL filter module cabinet
The hybrid modular active filter PQE hMF-UL is a UL-certified, ready-to-connect solution for compensating for network perturbations in industrial networks. It has a modular design consisting of individual filter modules and can be easily expanded if performance increases or requirements change.
Active and passive filter modules can be combined with the hybrid filter system of the PQE hMF-UL for every task. In addition, this cabinet is specially adapted to the requirements of the US market in order to meet the needs and standards of this market. This system can be conveniently operated on site via the 10-inch display and also enables remote access for remote maintenance, allowing maintenance work and adjustments to be carried out remotely.
PPM Active filter module
The powerful active filter module PPM (power processor module) compensates harmonics, load unbalances and reactive power with high reaction speed. The robust design predestines the PPM for industrial use.
PPM-W Filter module with water cooling
The powerful active filter module PPM-W (power processor module water cooling) compensates harmonics, load unbalances and reactive power with high reaction speed. The robust design predestines the PPM for industrial use.
Modules for connection to existing water cooling system
AHM Active hybrid filter module
The active hybrid filter module AHM is constructed in loss-reduced silicon carbide technology and has 50 % less losses compared to conventional active filters. In addition, it enables local energy recycling of harmonics using a patented process. The voltage-controlled filter module can be used to reduce mains perturbations both selectively and over a broad band. The modular design allows the filter to be expanded quickly and simplifies service. All connections are provided at the bottom of the cabinet. The operation is carried out via a web server.
Application areas of the AHM with a compensation current of 120 A:
ABM Active broadband filter module
The unique driving band filter module with true voltage regulation. Response times in the microsecond range allow optimal compensation results even with highly dynamic disturbance variables. By means of a power electronic simulation of ohmic-inductive or ohmic-capacitive loads, the filter is able to selectively change the grid impedance. This provides an elegant way of damping grid resonances. The increasing problem with supraharmonics (harmonics > 2.5 kHz) can be solved effectively.
FCM/FCS Harmonic filter module
The voltage-controlled harmonic filter module is a cost-effective solution for reducing individual harmonics. Due to its design, it fits seamlessly as a filter module into our hybrid modular filter series hMF. Wall mounting is also possible for single applications.
One master module FCM can control up to 5 slave modules FCS with the same or also different tuning frequency. This makes it very easy to set up filter circuit systems of greater capacity and expand them later. Parallel operation of the FCM and FCS modules with active filter modules is possible.
UBM Universal Broadband Module PQE
Grid disturbancies in the frequency range above 2 kHz, such as interference from inverter clock frequencies, commutation dips, or high-frequency signal levels, is an increasing and serious problem. These feedback effects are often amplified by resonance effects.
The universal broadband filter module is a cost-effective solution for reducing interference up to 20 kHz. Due to its design, it fits seamlessly as a filter module into our hybrid modular filter series hMF. Wall mounting is also possible for single applications.
The PQE UBM filters interference between the phases and phase against N/PE. This means that both common-mode and push-pull interference can be eliminated with one filter module.
