Grid emulators are specially designed for emulate grid disturbances. Each equipment integrates VSC modules and DSP control boards equipped with all necessary power components, electrical protections, auxiliary electronics and security elements. The power electronics unit of each emulator is a back to back topology formed by 2 voltage source converters connected in series. It is a multifunctional AC-AC converter that shows a wide range of applications. Grid emulators are specially designed for emulate grid disturbances. All the range of our Grid Emulators allows great flexibility to evaluate all type of scenarios. They can generate different type of grids and its common faults and disturbances.

Generates different types of grid:
• Three phase power grid (3F+N) from 0 to 440Vac.
• Power grid with variable frequency from 0 to 800Hz.
• DC Voltage Source from -750 to 750Vdc
Generates common grid defects as:
• Power grid with voltage harmonics control up to 15th (50-60Hz)
• Flickers (programmable amplitude and frequency) and overvoltage
• Generation of interruptions and voltage dips (type A, B, C and D)
• Three phase power grids with programmable variations in frequency
• o Impedance of grid variable
