Why HiL and PHiL are shaping the future of advanced power testing

That is why real-time simulation, Hardware-in-the-Loop (HiL) and Power-Hardware-in-the-Loop (PHiL) are becoming increasingly important for engineering teams working in power electronics, smart grids, batteries, renewables and e-mobility.

During a recent training session at Cinergia, OPAL-RT shared key insights into how HiL and PHiL help engineers validate advanced systems earlier, safer and under more realistic operating conditions

A closer look at HiL, PHiL and real-time simulation

The training session focused on the fundamentals of HiL and PHiL, as well as on the role of real-time simulation in advanced validation workflows.

In HiL, engineers connect real controllers or devices to a simulated system running in real time. This makes it possible to validate behaviour before full physical deployment, reducing risk and improving development efficiency.

PHiL takes this one step further by adding real power to the loop. Instead of testing only signal-level interaction, engineers can connect simulation to real power hardware and validate how systems behave under more realistic energy conditions.

Where Cinergia fits in PHiL environments

In PHiL setups, Cinergia acts as the link between the simulated world and the physical one.

While OPAL-RT manages the simulation environment, Cinergia converts simulated commands into real power signals for the hardware under test. This makes it possible to build more advanced and more flexible validation environments for demanding applications.

For companies working on grid-connected systems, batteries, converters or power electronics, this approach opens the door to safer and more configurable testing scenarios.

Why this matters for advanced testing

As applications become more dynamic and interconnected, traditional testing alone is often no longer enough.

HiL and PHiL help engineering teams:

• validate systems earlier in development

• reduce testing risk

• reproduce more complex operating scenarios

• gain more flexibility in R&D and validation setups

This is especially relevant in applications such as smart grids, microgrids, battery testing, renewable energy, PV inverter testing and e-mobility.

From simulation to real-world applications

One of the practical examples shown during the session was a real-time microgrid model built in RT-LAB.

The setup combined simulated grid elements and real hardware, showing how complex scenarios can be tested with greater realism and control. This kind of environment is especially valuable for engineers working on grid dynamics, controller validation and advanced power electronics behaviour.

Cinergia solutions for advanced validation environments

Cinergia develops regenerative power solutions designed to support demanding test environments across R&D, industrial validation and automated benches.

For highly versatile applications, the All-Terrain AC/DC Regenerative Converter combines Grid Emulator, Electronic Load and DC Bidirectional functions in a single platform, making it ideal for renewable energy, ESS, PV inverter testing, Power-HIL, battery testing and e-mobility.

For compact, high-performance testing setups, the SiC 50 family offers a next-generation solution based on SiC technology, combining flexibility, efficiency and broad test coverage.

For automated or space-constrained labs, the SiC-RSe provides a compact 19-inch rack-mounted solution with Mixed Mode functionality, easy integration and strong performance for advanced validation scenarios.
