OP1400 | 4-Quadrant Power Amplifier

4-Quadrant PHIL Amplifier

Revolutionize Your PHIL Tests with OPAL-RT’s High-Fidelity 4-Quadrant Power Amplifier

The OPAL-RT OP1400 is a 4-Quadrant Power Amplifier featuring high-speed and low-latency closed loop communications for real-time digital simulation. The power amplifier is designed to be used as a Power Hardware in the Loop (PHIL) testing tool in combination with an OPAL-RT simulator to form a complete PHIL testing solution.

Flexibility in a Constantly Changing World

Power Amplifier - PHIL Applications

Grid Emulator application consists to simulate larger grid on the simulator and close the PHIL loop with real DER or load to analyze the stability of the Microgrid controller.


Distributed Energy Resources (DER) and Converter Emulator application consist to simulate the DER source such as Solar Panel, Wind Turbine and Energy storage with its associate converter. The converter could be commanded with a real controller in HIL mode and the output of the converter is connected to a real microgrid bus with PHIL.


Distributed Energy Resources (DER) Emulator application consists to simulate only the DER source such as Solar Panel, Wind Turbine and Energy storage. The amplifier is connected to a real converter to emulate the DER source behaviour.


Grid Load Emulator application consists to simulate a load on the microgrid and the amplifier is connected directly to the bus.

The Perfect Power Amplifier to Optimize Your Testing And Validation

High Performance and Fidelity

The OP1400 4-quadrant PHIL amplifier is equipped with up to 6 amplification units of 5 kW each, in current and voltage control modes. It offers a closed-loop bandwidth up to 10 kHz with a THD of less than 0.75 %. It has a non-dissipative, 100% power sinking capability.

Modular and Integrated

The OP1400 components are rack mounted and allows integration of the OPAL-RT simulator, thanks to the low power density amplifier units. Fully compatible with OPAL-RT’s leading real-time simulation platforms, RT-Lab and HYPERSIM.

High Speed Communication Link

Benefit from high-speed, low-latency, 6.6 Gbps, optical interfaces for closing the loop between the simulator and the amplifier.

Discover Which Are The Key Factors to Consider Before Choosing Your PHIL Amplifier

Power Hardware-in-the-loop (PHIL) enables engineers to test various types of power equipment—including power converters, generators and motors—while benefiting from high-fidelity simulation that provides greater flexibility in applying tests that are not practical in a non-destructive manner on analog testbeds or on a real system.

In this white paper, learn the key considerations when selecting power amplifiers for your Power Hardware-in-the-loop (PHIL) Testbed.
