High-performance programmable power supplies and converters engineered for hardware-in-the-loop (HIL) emulation, aerospace grid testing, and industrial power system validation.
Unlocking deep hardware-in-the-loop performance, multi-quadrant energy recovery, and transient modeling for global grid testing requirements.
Modern electrical grids are undergoing their most significant structural shift since the Industrial Revolution. The rapid integration of variable renewable energy (VRE) assets, such as photovoltaic array fields and offshore wind farms, combined with the exponential deployment of electric vehicle (EV) charging facilities and battery energy storage systems (BESS), introduces unprecedented dynamic complexity. Conventional testing approaches are no longer sufficient to guarantee safety and performance. This is where high-precision power system simulators become critical infrastructure components.
A power system simulator goes beyond standard power delivery. It emulates dynamic grid impedances, voltage dips, phase interruptions, frequency fluctuations, and high-frequency harmonic injections. By creating a controlled replica of localized or national transmission networks, researchers, utility operators, and hardware manufacturers can stress-test physical equipment under extreme conditions without risking damage to the actual utility grid. For instance, when validating utility-scale solar inverters, a grid simulator must accurately replicate low-voltage ride-through (LVRT) and high-voltage ride-through (HVRT) anomalies according to international grid compliance standards like IEEE 1547 and UL 1741.
"A modern power system simulator acts as the critical bridge between mathematical modeling and physical hardware validation. Without realistic, high-speed emulation, the microgrid networks of tomorrow cannot be verified for transient stability."
Our programmable AC power supplies and high-power bidirectional DC systems provide the necessary performance and speed. Featuring low Total Harmonic Distortion (THD < 0.5%) and ultra-fast transient response times (under 1-2 milliseconds), our simulators allow engineers to run high-fidelity simulations. This ensures that safety relays, distributed generation controls, and automotive drivetrains respond safely to complex grid events.

Exploring the control architectures and hardware innovations that drive high-precision grid emulation.
Our grid simulators utilize Active Front-End technology, allowing power to flow bidirectionally. Energy generated by the device under test (DUT) is returned to the local utility grid with over 92% efficiency, reducing overall thermal footprints and operational utility costs.
Equipped with high-speed Digital Signal Processors (DSP), our simulators achieve ultra-fast transient responses (<1ms). This ensures precise tracking of custom waveforms, sudden phase jumps, and complex voltage fluctuations during grid-fault emulation.
Engineers can program and inject specific grid harmonics (up to the 50th order) to evaluate how equipment behaves under poor power quality conditions. This capability is essential for IEC 61000-3-2 and IEC 61000-4-11 compliance testing.
