Our fields of activity cover many areas of electronics. They range from consumer electronics to renewable energies. In the view below, some of our cases and the associated competences are listed to illustrate the range of our work.
One of the biggest problems in the rapidly growing e-mobility market is the insufficient charging infrastructure. There are already not enough possibilities to charge the existing number of electric vehicles. The need for new, functioning ways to solve this problem is enormous.
More and more charging columns for electric vehicles are being deployed. All in line with the idea of a green future and the switch from the combustion engine to the electric motor. This is an area that is enjoying rapid technological progress.
In this project, we have developed an innovative control and management unit for a charging station to be used worldwide for the booming e-mobility market. The product uses a cellular module to enable the end customer to use the system in an innovative and elegant way all over the world. The product was therefore developed to use the respective frequencies of the country and to be continuously online.
Electromobility is currently determining the future of the entire automotive industry and it's prioritized developments. The EU's decision that no new vehicles with combustion engines may be registered after 2035 and the advantages of buying an electric car support this enormously.
Electric and hybrid vehicles are highly technological machines that are not or only partially based on classic technologies. These vehicles require state-of-the-art power electronics to function and ensure safe driving.
In this project, therefore, new power electronics were developed for the latest generation of hybrid and electric vehicles. The innovation here was to optimize the control of the charging management in order to lead the technology into the future. We developed the power electronics up to the pre-series stage, accompanied them, and carried out an extensive derating.
The distributors of electrical equipment are subject to the legislators in the EU. In Germany, for example, they are subject to the law on electromagnetic compatibility of equipment, which requires them to comply with the corresponding protection requirements, which are laid down in the relevant standards in the form of limit values for immunity to interference or emitted interference. Complex electronic devices or machines generate electromagnetic fields that can be in a destructive relationship to each other. To ensure functionality, the design must be adapted regarding the electromagnetic fields.
This contract development included hardware simulation, hardware testing, and documentation management in the automotive field.
In the field of high-performance vehicles, partial electrification is becoming more and more important to achieve the increasing goals and offer customers a further increase in this area. The physical limits of combustion engines are slowly reaching their limits. Here, development is taking the step of supporting the combustion engine with additional electric power. This is a perfect combination of an internal combustion engine with it's typical characteristics and one or more electric motors that provide the missing support for the internal combustion engine at the right moment.
This project, therefore, involved a complete hardware redevelopment from layouting to prototyping to 0-series.
Everyday life is becoming increasingly fast-paced. People want to organize their time more efficiently and are therefore looking for ways to make everyday life easier. For this reason, the household and all the work around the house are increasingly supported and simplified by modern technologies. A vacuum wiper is a product that fits exactly into these times and serves to facilitate floor cleaning, as it combines several work steps.
In this project, work was therefore done on the technical development of an innovative control unit for a new cleaning device coming onto the market, with a suction and wiping function for private use. The development included all steps of hardware development from hardware design, circuit development, elaboration, and development of the entire software to prototype construction and production of the O-series. In addition, the project was coordinated and completed by MMD within the framework of an agile working method.
People want simpler and simpler solutions to everyday problems. For this reason, the field of household cleaning appliances is large and highly competitive. With this type of consumer electronics, the trend is strongly moving towards being able to use the devices independently of a power supply unit. Therefore, rechargeable batteries are finding a place in more and more of these devices, as they can be used more flexibly without a cable.
In this project, we developed the electronics for an innovative battery-powered "floor cleaner". The development encompassed the entire hardware development including layout, testing and prototype construction. The key point was a particularly intelligent charging and control management for this floor cleaner.
In the entire field of consumer electronics, the trend is to be able to use one power supply unit for many devices. These modular systems are more efficient, cheaper and save resources.
For the use of modern household appliances, the given power supply in the form of a power supply unit should also be used efficiently. The safety aspect must always be included.
In this project, the development of the entire appliance, including PCB and testing, was carried out using an agile working method.
Due to the shortage of components, the electronics industry is facing enormous challenges. In some areas, the crisis is becoming a serious problem as entire supply chains are under threat.
The current ongoing chip crisis started in the early 2020s and is caused by a combination of several factors:
A triggering factor was the Covid-19 pandemic resulting in lockdowns in China and pandemic-related outages in Malaysia.
A cold spell in February 2021 with heavy snowstorms in parts of the USA had an aggravating effect.
These caused production losses at semiconductor factories in Texas.
As a result of power outages, production at some key factories could not be shut down in a controlled manner, damaging machinery, and equipment in addition to production.
Shortly afterwards, there was a major fire at a Japanese semiconductor plant.
The market for semiconductors is now in a situation where increased demand for many semiconductor products is being met with limited inventory.
Since the manufacturing processes are sometimes very demanding, the production capacities cannot be increased arbitrarily and, above all, not quickly.
As for the causes, it must be borne in mind that production capacities for advanced semiconductor products were already well utilized before the crisis.
This brings us to an outlook on the situation for the coming years:
At best, experts expect the crisis to ease slightly in the course of 2023 and assume that the critical situation on the semiconductor market will continue until at least 2024.
We already prepared for these challenges at the beginning of the chip crisis and expanded the area of critical parts management. We will find the desired component for you or look for alternatives to maintain production.
We provide a solution even for seemingly hopeless component problems.

This contract development of a microphone control unit was implemented, including hardware testing and simulation.
In addition, tasks around the critical parts management were added, as there was a shortage of certain components.
Industrial roller doors are used in a variety of ways and must be adapted to a wide range of conditions.
Large exterior openings of commercially used properties are often closed with industrial sectional doors. They are used, for example, in logistics centers, warehouses, fire brigade bases, workshops, car dealerships or in agriculture. Modern roller doors should provide a safe, robust and durable closure.
In this project, work was done on the technical and theoretical development of a unit to control any type of industrial roller doors. The most important components of the innovation are formed by the implementation of intelligent automatic functions including novel memory modules. The unit uses the latest wireless technologies such as Bluetooth and Wi-Fi to be prepared for the future in the long term. The product has been developed according to appropriate standards and guidelines to be usable and certifiable worldwide.
Pumps are used in many areas of industry, from medical technology to the food industry to chemical applications. In this area, particularly precise pumps and the associated controls are required.
We took over the project management of the overall device development and certification of a precision mechanical dosing pump for industrial and medical use.
In this project, we developed a highly efficient and novel dosing pump for fine dosing requirements from many areas of industry. The most important aspect in this project was the highly efficient control of the pump, which covers several PCBs. Due to the current situation in the field of component management, many novel solutions were developed to be production-safe in the long run. Additionally, the device was developed to obtain the UL certification, which is important for the US market.
The energy crisis has shown us that we can no longer rely on fossil fuels in the short term. The industry has been trying to find alternatives to nuclear and coal power for a long time. A rethink of energy production puts the focus on the almost inexhaustible energy of the sun.
Energy production must be converted more and more to renewable technologies as quickly as possible, whereby energy production is subject to complex processes and a regulated flow of electricity must be generated in the process.
This contract development of a hardware for a new photovoltaic inverter generation was carried out, including tests of the pre-series boards.
