Introducing the Regatron TopCon TC.ACS Full 4-quadrant grid simulators, ‘HIL mode’ 4-quadrant voltage amplifier, Programmable RLC load mode
REGATRON’s 3-in-1 full 4-Quadrant, Regenerative, Bidirectional Source & Sink Grid Simulators (Grid Simulator, Power Amplifier and AC load) of the series TC.ACS are of a precisely engineered, high quality, modular design.
The latest multi-level inverter technology for high-resolution voltage / current patterns, allows the Simulator to cover the entire fundamental frequency range from DC up to 1000 Hz and up to 5000 Hz modulation bandwidth. A specialized multi-processor core prepares all relevant voltage / current shapes in real-time to ensure a very stable phase relationship and event timing throughout.

Key Features
Programmable testing parameters
The multi-level inverter technology common with a remarkable high switching frequency opens up the way to a wide base frequency range from DC up to 1000Hz and an exceptionally high modulation bandwidth of 5 kHz. Therefore, harmonic distortion up to the 100th harmonic @ 50 Hz or the 83th harmonic @ 60Hz can be exactly reproduced, assisted by a comfortable Fourier tool. Of course, the system can easily and comprehensively be adapted to the various tasks to be carried out within the fields of R+D, laboratory, end-of-line testing and education. By means of the application software ACSControl, the user is enabled to program the following parameters:
variation of basic system voltages and frequency
settings of phase relationship
voltage drops in the whole network or individual drops per phase
micro ruptures and flickers
over- and under voltages
voltage asymmetries
superimposed harmonic and interharmonic voltage waveforms
variation of phase angles
special conditions for EMC testing
transition from feeding to refeeding operation and vice versa
analyses of energy flow
Key Benefits
Application example: TC.ACS as an element of a Test Lab equipment
Comprehensive testing equipment for solar inverters, among others, integrates not only the grid simulation but also an additional simulation system for photovoltaic cells. The programmable TopCon Quadro DC power supplies together with the optional TC.LIN postprocessors in combination with the software tool SASControl form a finely graduated modular PV simulation environment. By using this testing equipment a PV inverter device can be comprehensively tested regarding the photovoltaic issue as well as in terms of the grid feed-in aspect.
