Grid Emulators
Grid emulators are an essential component of modern power electronics test environments. They enable the complete simulation of an electrical grid, including all variations and disturbances that may occur in real-world conditions.
Instead of relying on a fixed, stable grid, developers and test engineers can use a grid emulator to precisely determine how equipment responds to changes in voltage, frequency, harmonics, or imbalance. This makes these systems indispensable for testing EV charging stations, inverters, UPS systems, energy storage systems, and other grid-connected converters.
The TT&MS product range includes regenerative, programmable grid emulators from Cinergia and ITECH. These systems combine accurate grid reproduction with an efficient 4-quadrant architecture, allowing energy to be fed back into the grid during testing. This reduces operational costs and minimizes heat generation in the laboratory. The emulators can simulate both stable grid conditions and complex dynamic scenarios, ranging from simple voltage variations to complete sequences with dips, swells, flicker, and harmonic distortion. Most grid emulators in our portfolio are also suitable for Power Hardware-in-the-Loop (PHIL) applications via analog control. The power range extends from 2 kVA to >1 MVA
Cinergia offers a wide range of configurations, from single-phase to three-phase, and also provides combined systems that can function as grid emulators, DC power supplies, bidirectional DC power supplies, AC loads, or DC loads.
ITECH offers the IT7900 series, modular, scalable 4-quadrant solutions available in standard, high-voltage, and EP variants. The EP models are particularly suitable for test setups where both grid emulation and regenerative loading are required in a single system.
