Equipment used from the portfolio of Schulz-Electronic:
- 2 bidirectional DC power supplies type TC.GSS 400.400.S in racks, including BatSim- and BatControl software
The Flight Research Project.
Research on electric drives for motor gliders.
The Challenge
For a research contract in the field of aerospace, existing battery trolleys needed to be replaced by DC sources – so-called high energy sources – suitable for flexible uses.
A university in Baden-Württemberg issued a public call for tender when looking for a partner for this project – and found Schulz-Electronic …
The Solution
Particularly in the area of research, inexperienced students can cause dangerous situations with battery trolleys that have voltages up to 500 V DC and outputs that are sometimes in excess of 30 kWh. Here no risks can be taken. However, a high voltage source needs to be available which is mobile and – unlike battery trolleys – does not need recharging after every experiment.
For this reason Schulz-Electronic used source-sink devices by Regatron. The bidirectional TC.GSS power supplies are used to operate a two-part system which delivers either 800 V / 100 A or 400 V / 200 A, depending on how it is connected (in series / in parallel). Thanks to two separate mobile racks, each subsystem can be operated independently.
Additionally software packages are integrated into the plant that enable it to be operated as a battery simulator or as a battery test system. To do this, for ease of connection the Slave’s AC plug can be connected to the Master.
Especially important: numerous specially developed and implemented protection mechanisms ensure that students can also use the system without danger.
