To test power electronic devices such as electric drives, energy storage or utility interfaces, the process has to be supported by Hardware in the Loop (HIL) systems based on electronic emulators.

For such applications EGSTON POWER ELECTRONICS offers galvanically isolated high-speed interfaces allowing dynamic control with minimum latency.

HIL simulators are used in power system and power electronic applications to test protection equipment and electronic controllers. The device is connected to a simulator that runs the electric circuit using low levels of power, voltage and current. This concept is also used to test power components that require high power flows. It is called Power Hardware-In-the-Loop (P‑HIL) and must be interfaced and connected using voltage and power amplifiers.

EGSTON – and you’ve got the power!

P‑HIL simulation is a scenario where a simulation environment virtually exchanges power with real hardware like power converters, generators, FACTS and so on, in contrast to the usual hardware-in-the-loop simulation, which creates signal exchange only. EGSTON provides turn-key Power Electronic Test Benches based on P‑HIL technology in a power range from 100 kVA up to 2 MVA.

Applications and emulation models run on real-time FPGA and standard HIL platforms that are an integrated part of the test benches. The high voltage bandwidth is 5 kHz at 440 VRMS and harmonics up to 20 kHz can be generated. This technology can be used as AC source/sink, DC source/sink, smart grid‑, aerospace grid‑, PV-module‑, battery- or electrical machine emulator and even more.
