Power Quality from MBS-MP
Chokes and filters from MBS-MP ensure trouble-free and long-lasting operation of motors in converter-controlled drive systems. Our engineering team uses its expertise to provide a choke or filter solution that is perfectly tailored to your drive train.
With our experience, expertise and high level of vertical integration, we are able to develop, design and manufacture customised chokes and filters specifically for your application. We always guarantee standard-compliant design in accordance with EN 61558-2. Our choke range includes motor chokes, mains chokes and common mode chokes.
In the field of filter applications, we specialise in dU/dt filters and sine filters, among other things. Our specialists always find the right solution for a wide variety of applications and sometimes highly complex requirements: single-phase or three-phase, for DC, 50/60 Hz or even for high-frequency requirements, up to 5,000A rated current. Our aim is to always offer you the technically and economically optimised product solution: copper wire or tape winding, magnetic sheets or ferrite cores. Flexibility is our strength.

Single-phase and three-phase input chokes, especially mains chokes, protect the converter input by smoothing the current flow and ensure that unwanted mains feedback (current distortion) caused by commutation during converter operation is limited. Input chokes from MBS-MP optimise the performance of the converter and ensure power quality. In addition, the input choke limits high inrush currents to protect the connected converter.
Single-phase and three-phase output chokes, especially motor chokes, limit the voltage slope in long cables between the converter output and the motor and ensure trouble-free motor operation. Output chokes from MBS-MP reduce interference and errors alike and protect connected drives. They ensure performance optimisation of the drive system.
By combining inductance (choke) and capacitance (capacitors), we can also offer you our chokes as input or output filters.
Output filters are particularly relevant here. These include all filters, such as du/dt or sine filters, which are connected downstream on the output side of frequency converters in order to convert the disruptive clock frequency components of the frequency converter into a compatible sine wave voltage form. The downstream motors are protected from damage by the steep voltage edges.
The use of a sine filter is particularly important for long motor cables, older motors or standard motors. Filtering the high-frequency interference signals also improves EMC immunity. In addition, the sinusoidal voltage induced by the sine filter prevents disruptive motor noise.
Typical converter-controlled applications: Conveyor systems, crane systems, machine and plant construction, precision machines with typical operating conditions due to long motor cables, operation of standard motors on frequency converters, increased EMC requirements, special network conditions.
