Bipolar amplifier.
A bipolar amplifier is distinguished from a ‘normal’ power supply, because it has the ability to operate in multiple quadrants.
The bipolar, two-quadrant model can supply power at positive or negative voltage. A common application is to enhance the output power of an (arbitrary) function generator (quadrant 1 and 2). However, a bipolar two-quadrant model may also be structured so that it is able to supply or dissipate electricity at a positive voltage. Such units are ideal for, for example, charging and discharging batteries or supercapacitors (quadrant 1 and 4).
A four-quadrant bipolar amplifier is capable of both supplying current (power supply) and absorbing current (load). All of which, of course, at both positive and negative voltage. A good example is the control of RCL networks, at which the capacity or coil generates energy back into the power supply when it is disconnected.
In our product range we carry Höcherl&Hackl amplifiers, Toellner, NF Corporation Cinergia, and Newtons4th with power up to 200kVA, voltages up to 750V, but also frequencies up to 50MHz.

ABB
"The ABB Power Grids Jumet organisation is an innovative development and production facility of ABB that manufactures active filters and battery energy storage systems to support a stable grid. To test these systems we have acquired two Cinergia GE/EL +120kVA eplus units capable of doing grid emulation (AC + DC), operating as an electronic load (AC +DC) and being a battery emulator. We have experienced very good support from TTMS in obtaining these two Cinergia units. This included organising an on-site demonstration and supplying loan systems prior to the delivery of our final systems. This way we could start testing as early as possible. TTMS also organised training for the operators from the original manufacturer. This support allowed us to introduce the first battery energy storage systems even prior to the full delivery of the Cinergia systems."

“At the Energy and Environment department of the Faculty of Science, Technology and Medicine (FSTM) of the University of Luxembourg we do have different research projects related to green energy contributing to the development of eco-cities. As a long-standing partner of our research unit, TT&MS has proven that they are able to answer even the most complex questions in a professional manner. They have shown that they are always up to date with the latest technology and do not spare any effort to look at the application and even the situation on site. The exchange of ideas was always very pleasant and took place quickly. We look forward to further years of fruitful cooperation.”
