OP8110 | 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 OP8110 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 OP8110 power amplifier is equipped with two 3-phase modules of 5kW, 120Vrms 14A per phase, and up to 10kHz (-3dB)—all of this coming in with less than 0.5% total harmonic distortion (THD). 100% compatible with OPAL-RT’s real-time leading simulation platforms RT-LAB and HYPERSIM.

High Density

High Density

Features a low mechanical volume and low cost, and at just 19" wide, boasts overload, short circuit and over temperature protections. The power amplifier also features non-dissipative regeneration, and is fully integrated in a small form factor 2U chassis to be rack-mounted.

High Speed Communication Link

Benefit from high-speed-enabled communications with low-latency SFP communication interfaces to close the loop with the real-time simulator--thanks to the up to 6.6Gbps, internal closed loop at 1.67us.

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.



Go Beyond: Empower Your Microgrid Testing Laboratory

Ideal for both research and educational, the OP1400 Microgrid PHIL Test Bench combines OPAL-RT’s simulators and the new OP8110 4-Quadrant PHIL Amplifier. It uses a model-based design and testing methodology to simulate microgrid topology (SIL), to validate microgrid or power electronic controllers (HIL), and to interact with real microgrid components (PHIL).
