Dynamic Range Extender
The present invention describes a device for the recovery of electrical energy from electromagnetic radiation. To power electronic devices, there are different approaches.
Our society’s increasing energy demand requires a high degree of uninterrupted utilization of power generation plants.
Effective hydrogen production
At the Ruhr University Bochum an effective method was developed with which the coating of an electrode can be achieved with high long-term stability, especially during electrolysis such as alkaline water splitting. Due to the coating of the electrode surface with catalytically active material, a significant reduction in the required cell voltage is achieved.
Isokinetic aerosol sampling is currently only designed and used in very narrow speed ranges. However, known diffusers are only permanently adjustable and designed for a specific flow velocity.
Previous solutions or approaches to the elimination of oil spills on water surfaces consist either of actively working pumps, chemicals or materials that absorb the oil and then have to be cleaned or disposed of.
Method for current measurement in half-bridge topologies
A number of different instrument transformers are used to determine voltage and current in regulated power electronics. Current measurement becomes more and more difficult with increasing current intensity, especially since the switching frequencies increase due to the use of modern (e.g. GaN) transistors and parasitic properties of the sensors must be minimized.
The electrical power grid is undergoing a major transformation. Increasing numbers of decentralized feeders have been added in recent years and, in the future, there will be a large number of charging stations for electric vehicles that temporarily draw a large amount of electrical power from the power grid.
Fault Identification in DC Grids
The proportion of electricity generated by renewable energies is growing steadily, as is the proportion of DC power in the energy consumption.
