Over the past few years we have worked successfully on numerous projects. Some of those we will present here.


In the BMVI funded project GUW+ a controllable reversible DC substation has been developed which connects the existing infrastructure for the energy supply of light rails and trams with charging stations for electric buses. In addition, a battery storage unit by 2nd-Use automotive batteries of electric buses is installed in GUW+. This storage is used to avoid peak loads, temporarily store excess braking energy from trams or light rails and provide energy on demand.

In this project a GUW+ is implemented together with the Hannoversche Verkehrsbetriebe (ÜSTRA) in Hannover Döhren demonstrating and evaluating certain functionalities.

M&P provides systems for a compact charging infrastructure with isolated DC/DC-converters with output capacities of 75 kW and an output switching matrix to connect several charging points. To connect the battery storage, bidirectional step-up and step-down-converters will be provided further on. Additionally, M&P contributes to the development of a control-side information network within the GUW+ with gateway and device management in a central PLC.

The GUW+ project has received funding from the Federal Ministry of Transport and Digital Infrastructure (BMVI) within the funding program Electric Mobility. The program is coordinated by NOW GmbH and implemented by Project Management Jülich (PtJ).

Rail Brake Drive and Control System 2 (RDCS 2)

The Rail Brake Drive and Control System 2 (RDCS 2) is an electric drive system for operating electrodynamic rail brakes in Marshalling systems. By providing the peak power of the electrodynamic rail brakes (simultaneously up to 4 x 400 kW) via a high-performance energy storage, the power consumption from the mains can be reduced to a maximum of 80 kVA. Because of the very low power consumption and the small required power input significant cost savings in the energy supply are given.

The power electronics of the RDCS are designed with multiple redundancies from the infeed to the power provision and thus achieved a high level of availability. In the event of a mains failure the buffer serves as a USV to ensure a safe emergency shut-down. The RDCS 2 is almost maintenance-free and reaches the safety level 1 (SIL 1). Due to the high availability and very low maintenance the costs throughout the life cycle of the plant (LCC) are very low.
