This paper contains a concept for a testing device for charger. This mobile testing device affords an on-site inspection of charging stations, using the CHAdeMO protocol. Being a current sink, the dummy emulates the behaviour of an electric vehicle and communicates with the charging station. Current profiles can be requested, error scenarios can be created and the correct operation can be checked...

In this paper is shown the implementation of different layouts of a coreless planar transformer for a flyback converter. In addition, a 0.5W DC/DC converter was developed. The converter is based on a flyback converter for simple applications. The transformer is designed in a form as a spiral coil on a PCB. The special feature of the converter is that the flyback converter is laid out without a core...
The decrease of fossil energy and increase of available renewable energy places the Electric Vehicle (EV) into a new point of view as a modern transport system for individual mobility. Whether you live in a town or on the countryside different energy sources within EVs offer a wide range of usability. Anyway the resulting energy being used by the engine is electrical energy [1], [2].
In this paper the development of a 0.5 W DC/DC converter is presented. The special fearture of the converter is that the flyback converter is laid out without a core on a PCB. The paper shows a way of the implementation of the coreless planar transformer. An analysis shows some results by different geometry and frequency of the planar transformer. This DC/DC converter is adjusted for special current...
Current sensors have an important part in the technical world. A special part is by photovoltaic. The efficiency of the system can only increase by means of the MPP-Tracking with high precise current sensor. Furthermore, the inverter with the three phases should measure balance or unbalance effects. In this case, this paper will present a novel system (AC-DI module). This module has four high precise...
Simulation tools like Matlab/SIMULINK, PSpice, Multisim. etc, don't simulate the practical behavior of measurement devices and only deal with ideal characteristics. The problem of ideal current sensor is the accuracy of the calculated value. The simulated value has a high accuracy, which depends on of the processor. For example, a 32bit processor achieves an accuracy of 1/32bit =2,328.10–10. This...
Maximum power point tracking (MPPT) techniques are employed in photovoltaic (PV) systems to maximize the PV array output power which depends on solar irradiance and temperature. Most of these techniques depend on the measurement of the current sensor which needs to be simulated on the design phase. Simulation tools like Matlab/SIMULINK, PSpice, Multisim. etc, don't simulate the practical behaviour...
Compared to conventional current sensors, the proposed topology is advantageous because of its high resolution throughout its full measurement range, thus reducing offsets to a minimum. This aim is reached through active offset compensation using an analog/digital chopper/de-chopper. A further advantage is the excellent suppression of 1/f noise and a low noise density (35 nV/√Hz) down to the DC-threshold...
In this paper the development of a 1W DC/DC converter is presented. It is based on a flyback converter for simple applications. The transformer is designed in a form as a spiral coil on a PCB. The special feature of the converter is that the flyback converter is laid out without a core. The area (diameter) of a spiral coil should be bigger as a coil with a core because the air is not a good energy...
