Compensating for Leakage current
Efficient charging of traction batteries is a key technology for the success of electric vehicles on the market. To this end, concepts for transformerless on-board chargers are currently being increasingly considered. Interfering high leakage currents to ground can be prevented or compensated for by this invention.
Optimized Amplifier Circuit
Shunt current measurement techniques are used in electric cars and in the charging stations. Special control of the circuit allows amplifiers to be ramped up to the operating point very quickly, safely and reliably. The amplification factor can be adjusted over three orders of magnitude.
Smart charging for electric vehicles
There is a growing trend for electric vehicles. Their drive batteries require charging at high power from the available AC power grid. Three-phase on-board chargers (OBCs) are used for this purpose at high power outputs of at least 11 KW.
Synthetic Image Data
Almost all car manufacturers are currently developing camera-based autonomous or semi-autonomous vehicles.
Intelligent charging for electric vehicles
Short charging times are essential for the acceptance of battery-powered vehicles. As a result, three-phase on-board chargers are increasingly being installed in electric vehicles as they significantly reduce charging times compared to single-phase charging circuits.
DC-DC resonant converter
Flexible chargers for batteries (especially in the field of e-mobility), fuel cell applications or flexible photovoltaic battery combinations all contain switch-mode power supplies with DC converters, DC-DC converters in short.
