FAQ
Find the answers to your questions
What is the OP1400 4-quadrant power amplifier used for?
Our OP1400 4-quadrant power amplifier is designed for real-time digital simulation environments, providing high-speed and low-latency closed-loop communications. We use it primarily as part of a Power Hardware-in-the-Loop (PHIL) testing setup, enabling engineers to seamlessly integrate real and simulated components like grids, DERs, converters, and loads.
What makes the 4-quadrant power amplifier ideal for PHIL testing?
We engineered the OP1400 4-quadrant power amplifier with full sourcing and sinking capabilities, rapid time delays of just 5.5 to 8.3 microseconds, and a closed-loop bandwidth up to 10 kHz. These features ensure high-fidelity emulation, minimal distortion (<0.75% THD), and robust communication links (up to 6 Gbps) with our OPAL-RT simulators, making it an ideal solution for flexible, non-destructive PHIL testing.
What configurations are available for the OP1400 4-quadrant power amplifier?
We offer standard OP1400 configurations based on amplification units of 5 kW each. Depending on your needs, you can choose from models delivering 5 kW, 10 kW, 15 kW, or 30 kW rated power. If required, we can provide custom configurations beyond these options to meet your specific testing requirements.
How does OPAL-RT’s OP1400 4-quadrant power amplifier enhance real-time simulation performance?
Our OP1400 4-quadrant power amplifier ensures that real components behave accurately within a simulated environment, thanks to its voltage and current control modes, high-speed SFP communication links, and precise transient handling (20 A peak). This real-time performance is critical for next-generation power systems development across industries like energy, automotive, and aerospace.
What should engineers consider when selecting a 4-quadrant power amplifier for PHIL applications?
When choosing a 4-quadrant power amplifier like the OP1400, engineers should consider factors such as closed-loop bandwidth, time delay, sourcing/sinking capabilities, transient response, and software compatibility. We offer a detailed white paper to guide you through these essential considerations, helping ensure you select the right amplifier to meet your PHIL testing goals.
