Soon, rotating inertia of generators use for grid control must be replaced due to the growth of distributed renewable energies. Here, we propose to let also electronic loads contribute to future virtual inertia. It is suggested to use DC link capacitors of power supplies for this task. This requires 5 W, 50 J and a capacitor size of about 200 cm3 per installed kW, corresponding to the size of single...
Wireless power transmission systems can be optimized by matching the resonance frequency of a receiver. However, in certain applications, such as, e.g., a multireceiver system, it is desired to match the individual resonance frequencies of the receiver to a fixed (e.g., common) operation frequency. In this publication, a method is proposed to match the resonant frequency dynamically without changing...
