Triphase PHIL

Power Hardware In the Loop Reimagined


Triphase PHIL (Power Hardware In the Loop) creates a controlled environment that implements real-life conditions on a Device Under Test (DUT). Conditions include high dynamic voltage, current or torque patterns as well as low level signals and communication. Conditions can be programmed, played from file, or provided by a closed-loop simulation. Typical DUTs include AC/DC and DC/DC converters as well as drivetrain components such as motors and gearboxes.


The Triphase PHIL platform offers bidirectional power systems for AC, DC and motion control applications ranging from 15 kW up to 2 MW. It has its own real-time Simulink toolchain, and can integrate with simulator and test automation platforms from 3rd-party vendors such as Opal-RT, RTDS and NI. As such, it is an ideal candidate for testing (micro)grid and drivetrain components in both R&D and end of line applications.

A typical Triphase PHIL setup is comprised of the following components:

  • Power Module: power supply + output section configured for your DUT (AC, DC, Motion Control and combinations thereof).
  • Power Management: low level voltage, current and torque control loops, safety, application software. Linked to Power Module over real-time network.
  • 3rd-party platform: Optional. To run more extensive, application-specific simulations and test automation/analysis. Linked to Power Management via (real-time) network.
  • DUT: the device you want to test against the emulated environment.

We have a team of experts available to help you determine the best solution for your requirements. We analyze, evaluate and determine the feasibility of your application and can offer standard solutions as well as systems tailored to your test scenario and DUT. Contact us with your requirements.

System Approach

The Power Management Unit (PMU) is an linux machine that can communicate with a wide variety of 3rd-party platforms as well as the DUT. Standard supported communication interfaces include SFP, UDP, MODBUS/TCP and CAN. Triphase also develops its own PCIe cards for real-time inter-PC communication. Contact us with your requirements.

Supported Devices Under Test

Triphase PHIL modules can be configured to interface with a wide variety of electrical and mechanical Devices Under Test (DUT). Typical examples are AC/DC and DC/DC inverters, grid-connected systems, battery and supercapacitor packs and e-motors and gearboxes. Triphase also delivers tailored PHIL solutions for combined DUTs, such as a motor/inverter combo. Contact us with your requirements.
