The Cinergia GE+ vAC/DC series comprises 13 models from 7.5 kW to 160 kW and offers "Same Power in AC and DC". Each device can freely specify grid characteristics such as voltage, frequency, phase angle and (inter)harmonics up to the 50th order per phase; THDi on the grid side < 3 % at cos φ > 0.98 ensures a clean feed-in. The 30 kHz control loop and extensive interference profiles (including IEC 61000-4-11/-13/-14/-28, LVRT, SEMI-F47) enable reproducible tests. Applications range from electromobility & charging infrastructure to energy storage, PV/PV emulation, smart grids and power HiL.
- Generation of global grids: 3-phase/1-phase/split-phase, independent phase parameters incl. harmonics & ramps.
- Disturbance & standard tests: Dips, flicker, frequency jumps, (inter-)harmonics; editor & ready-made IEC profiles (pre-compliance).
- DC multichannel: Up to three independent bidirectional DC channels (common ground), CV/CC/CP/CR modes, battery test/emulation & PV emulation optional.
- Regenerative & parallelizable: regenerative for energy recovery; master/slave via LWL for power/voltage increase.
- Operation & integration: 4.3″ touch, open Modbus TCP interface (LAN), analog/digital I/Os, data acquisition.
Variant in focus: GE+ 200 vAC/DC
The GE+ 200 vAC/DC model offers a rated power of 160 kW - identical in AC and DC - and is therefore the top variant in the series. It addresses high-performance test environments in development, validation and production, e.g. traction inverters, large HV battery systems, fast charging infrastructure, stationary storage, grid converters and power HiL test benches with realistic transient profiles. In AC mode, the device delivers up to ≈233 A (3-channel) or ≈699 A (1-channel parallel mode). In DC mode, ±≈233 A (3-channel) and ±≈699 A (1-channel) are available. The regenerative architecture reduces energy and cooling costs in continuous operation, while the fast control ensures reproducible results in standard and fault tests.
Comparison with the other models in the series
- Power/scaling: At 160 kW, the GE+ 200 vAC/DC is the most powerful series version and significantly outperforms the GE+ 160 model. Master/slave operation with up to eight units is possible for even higher total outputs.
- Currents: The high rated currents (AC and DC) enable tests on large inverters, high-current chargers and DC distribution grids with wide load windows and steep ramps.
- Design: Large cabinet design for stationary test benches (typically approx. 850 × 900 × 2000 mm, ~680 kg) with powerful airflow for continuous operation under high load.
- Functionality: Full standard scope including grid simulation, (inter)harmonics, flicker/dips, frequency jumps, sequencer and optional battery & PV emulation and DC multichannel.
