The ITECH Electronics IT7900 Regenerative Grid Simulator High Voltage Series is a high-performance programmable AC grid simulator engineered for advanced power electronics testing, renewable energy validation, and grid compliance applications. Designed for demanding laboratory and industrial environments, the IT7900 series operates as a full four-quadrant regenerative grid simulator and power amplifier, enabling both power sourcing and sinking with energy recovery capability.

The system supports AC, AC+DC, and three-phase output modes with voltage ranges up to 700 VL-N and 1050 VL-N, making it suitable for testing photovoltaic inverters, PCS systems, energy storage systems (ESS), V2X/BOBC systems, microgrids, and Power Hardware-in-the-Loop (PHiL) simulations. With up to 88% energy regeneration efficiency, the IT7900 series reduces power consumption and cooling requirements during high-power testing.

The integrated touch-screen interface, built-in oscilloscope, harmonic analysis, programmable output impedance, and arbitrary waveform generation capabilities allow engineers to simulate real-world grid disturbances including voltage sag, surge, frequency variation, phase jump, LVRT, and harmonic injection scenarios. The platform also supports regulatory and immunity testing based on IEC61000 standards.

The IT7900 series is widely used in renewable energy laboratories, EV powertrain testing, aerospace power electronics validation, battery energy storage development, and industrial R&D applications requiring accurate and repeatable AC power simulation.
