Swedish research and technology easily end up outside the country's borders. Through the acquisition of MagComp AB's unique and patented inductor technology Magchoke, Comsys AB ensures that the technology is protected and developed further.

When MagComp, a Swedish company with roots in Lund University, decided to sell the part of the company that focuses on inductors, Comsys made sure to win the negotiations.

MagChoke- With the acquisition of MagComp's inductor operations, we ensure that Swedish research, technology and expertise stay in the country. We also secure a key component in our existing products, at the same time we gain access to resources to further develop the technology, says Marcus Löfgren, CEO of Comsys.

The patented technology MagChoke® is about replacing the conventional magnetic core with inductors with metal powders that are mixed in epoxy and then moulded around the coils, giving unique properties at the same time as the manufacturing cost is lower.

The power electronics company Comsys, with the product ADF Power Tuning, has a solution that delivers the right power quality to industrial customers all over the world. An important ingredient in the ADF is precisely inductors, which act as "shock absorbers" for quick changes in the electric current.

Today's society is becoming increasingly dependent on electronic equipment, while the quality of the electricity network is falling and the vulnerability is increasing, component damage, disruptions and long power outages are becoming increasingly common.

- The increasing use of electricity also creates a risk for energy shortages and an infrastructure that is not related to the rapid development. When, for example, a car or bus is to be charged in a very short time, parts of the electricity grid do not cope with the load, but there the ADF helps the technology and relieves the process. 
The need for energy storage and micro networks increases and the inductor technology in MagChoke® will continue to be important building blocks in our products in these areas, continues Marcus Löfgren.

Manufacturing and personnel are transferred to Tramo ETV in Eslöv, a well-reputed company that for more than 30 years has built up a solid experience through the manufacture of just inductive components.

Through a share swap, Comsys AB, the creator of ADF Power Tuning, has acquired Netpower Labs in order to become a full-service supplier for the next generation power grid

Through a share swap, Comsys AB, the creator of ADF Power Tuning, has acquired Netpower Labs in order to become a full-service supplier for the next generation power grid. Netpower Lab’s CEO Stefan Lidström will continue as Product Manager within Comsys.

Marcus Löfgren, CEO of Comsys ABThe acquisition of Netpower Labs, means that Comsys now will be able to offer a complete toolbox for system integrators to create the next generation power grid.

Marcus Löfgren, CEO of Comsys AB, explains why they made the move to acquire Netpower:

We saw a great fit in Netpower as we move into battery storage, EV, and solar applications. We were impressed with the breadth of development, as well as the quality of the products from Netpower. 380 V DC enables extreme power savings while eliminating many power quality issues such as unbalances and THD that we are commonly addressing with our current ADF technology.

Globally, Comsys sees immense potential in the area of energy savings - which Netpower Labs can facilitate. For Example, the data center industry is an extreme power cunsomer and growing constantly. It currently consumes 3% of global power*. With potential energy savings in the 15-30% range, it is extremely profitable to implemant 380 V DC in new projects, and there is also significanty less drain on resources and the environment. Data center power losses in particular are becoming a more urgent problem going forward. Data will cost significantly more, in terms of power, thus rerquiring efficient solutions. 

“The power grid is changing fast, as renewables and EV-mobility are adapted at an exponential rate. The development puts great strain on the power infrastructure. The combined solutions of Comsys and Netpower Labs enable highly efficient solutions for microgrids, peak shaving, grid stabilization, as well as integrated solar, so called DC charging”, Marcus Löfgren says.

The telecom industry is also moving towards the next generation mobile netowrks, 5G. This shift will require new types of power feed where Netpower has ready solutions for base stations in buildings and blocks.

Stefan Lidström, CEO of Netpower Labs AB, why the chose to join Comsys:

“We saw a big opportunity in using Comsys’ network to reach out with our DC-current solution. DC power is in many circumstances simpler and more robust than AC power and 380 V DC can be used directly in today’s products for LED-lights, computers, battery storage, solar and EV chargers. Together with Comsys’ know-how in AC applications and their global partner network, we will be able to serve large commercial installations”, Stefan Lidström says

Comsys will use its global ADF Partner Network to offer Netpower’s DC solutions worldwide.

This year we celebrate 10 years since the launch of the ADF P300.DSC04599 1

The launch of the ADF P300 marked two important ventures for Comsys:  it was the first fully standardized product from Comsys, designed with key industrial applications in mind; and it was the first truly modular active harmonic filter with general commercial availability. 

With an integrated web based user interface (WUI and ADF Dashboard), the ADF P300 raised the bar for user-friendliness and ease-of-use in advanced active filtering solutions. This, combined with the ability to handle not only harmonics but also reactive power, unbalance and flicker, made the ADF P300 the ultimate power quality tool box.

“We would like to use this anniversary as an opportunity to say thank you to our loyal customers,” says Jonas Persson, Head of Products & Services. “The ADF P300 is the benchmark product to beat in power quality. We will keep innovating to provide the best power quality solutions for the next 10 years as well.”

Since its inception many have followed, but the ADF P300 has not stood still. Originally launched as air-cooled, the ADF P300W – the liquid cooled variant of the ADF P300 – was launched in 2008. It featured increased power density, with an IP54 rating. At that time, it featured the highest power density of any active filter, saving space for the customer. This unit was also the second active filter to the market that provided 690V as an option from the start, but it was the first with modularity and 690V.

ADF P300Befitting Comsys’ project heritage, the ADF P300 has been used in a number of medium voltage applications, connected to the grid via a step-up transformer.

The ADF P300 has undergone various changes, from voltage adjustments to grid compatibility, but today it remains the most flexible and complete power quality solution on the market.  With ABS-approval for marine applications in 2015 and the newly added capability of Sensor-less control, it is now an even more versatile tool.

Over the years, the ADF P300 series has found applications in segments from industrial applications, variable speed drives, water treatment, electric arc furnaces, oil & gas (both land drilling and off-shore), marine applications, data centers, airports, STATCOM applications, numerous flicker applications, inductive heating, automotive industry, and many more. Although it’s just 10 years old, the ADF P300 has an unbeatable track record.


ADF Power Tuning was developed by Comsys AB in Lund, Sweden. Working with their global network of partners, the ADF Partner Network provides active filter solutions to industry leaders worldwide, enabling them to increase productivity, and simultaneously save money while reducing their carbon footprint.
