We are working on a forum and a separate webpage. If you have any question please don't hesitate to contact us via email!


Superimposed HVDC/AC Voltage Supply

With growing usage of power electronic devices in electric energy networks, new test methods and test procedures are needed to ensure a safe and reliable operation. Therefore, our goal is to build a voltage source which provides high voltage (ac or dc) with a superimposed high frequency voltage ripple.

The voltage source is built with a 100 kV test transformer together with the TAPAS board on high voltage potential. The TAPAS board is controlled via a galvanic separated controller and is fed by a secondary winding of the test transformer.

The team members are: Benedikt Riegler, Oliver Pischler, Bernhard Schober and Dennis Albert.

Needed: 1 TAPAS board

    Hi Dennis,

    Thank you for your submission!

    It would be great if you could offer some more Information on how you plan to implement your Idea. 

    Out tips might help you here: 

    How you should describe your idea

    • What is the¬†goal¬†of your project?
    • How does the¬†technical set-up¬†look like?
    • How do you want to¬†implement¬†your idea? (step-by-step guide, schematics, plan, video or presentation will help!)

    Best,

    The goal of our project is to provide a highly accurate, controllable and dynamic voltage source for multi-propose use. Nowadays, more power electronic devices are added to the power grid. Therefore, is very for example important to know how the devices react to DC voltage which is superimposed with a high frequency AC voltage.

    The TAPAS board will be operated on high voltage potential (e. g. on 100 kV ac or dc) and is fed by the secondary winding of test transformer.

    In a first step we will implement the control algorithm on microcontroller and test the functionality of the TAPAS board. In a second step the TAPAS board will be connected to the test transformer via a diode rectifier, in order to supply 48 V dc to the board.

    During the third and last step, test case will be used to show the performance range of the new build voltage supply.

    Attached you can find a Matlab/Simulation with one half-bridge. Depending on the Modulation/control of the half-bridge the sinusoidal output voltage is superimposed with a high frequency signal.

    In the attached files you will also find the fft of the output voltage without any superimposed voltage (fft_output_voltage.jpg) and a fft analysis of a superimposed voltage (fft_superimposed_output_voltage.jpg). The THD is visibly increased in the second case.

    Hi Dennis,

    thanks for the details and updates! :-)
    Congrats. We will provide you one TAPAS board. One of my colleagues will message you shortly.

    Hi Susanne,

    thank you very much. We are looking forward to start our lab setup with the Siemens TAPAS Board.

    Best regards,

    Dennis

    Hey Dennis,

    thanks,That sounds good. 
    Keep on working great :-)

    Hi Nore, would you also provide the JTAG adapter to USB you sugess in the short description, in order to debug and run ower own one code on the microcontroller? Because the software which is generally on the microcontroller looks like that it is adapted for electrical machines...

    Thanks in advance for your help

    Hi Dennis,

    We don't provide any  USB JTAG debugger. The default firmware will work with TAPAS GUI .

    But is it possible to control the switches directly via the raspberry (are there any software functions in phyton for this application)?

    We only found functions for motor control applications.

    Thanks and BR

    Hi Dennis,

    You will have to program using CCS to get full control of what you need in your application and no; we don't provide any python API for raspberry PI to control TAPAS. If you go through the TAPAS quickstart guide and check out the sample demo project, you can see how to can establish communication between TAPAS and raspberry PI.

    Hi Dennis,

    Don't forget that the submission deadline for your presentation is on 24th of June! We are already curious to see the results of your project :-) Keep in mind that you still have time to work on the implementation of your idea after the submission!

    Please post your project visualization and all related documents within your idea board entry :-)

    Best,

    Jacqueline @ TAPAS Team
