Versatile AC and DC Sources for Device Testing

Modern AC and DC devices are subject to rigorous validation techniques during both R&D and end-of-line tests. These tests require advanced, high dynamic voltage and current profiles that interact with the Device Under Test (DUT)'s behaviour.

To this end, Triphase designs and manufactures PMx: a range of programmable 4-quadrant AC and DC power sources, available in configurations from 15 kW up to 2 MW. Using a modular hardware and software approach combined with advanced digital control and measurement techniques, we can offer a high degree of customization while remaining cost effective.

Solution Overview

Triphase employs an integrated hardware/software and electrical/mechanical design approach to deliver customized test systems.

Our core expertise lies in the power conversion system and its control. We also provide a seamless integration with your DUT as well as your test automation and simulation platform.

We take your project from the design phase through to final commissioning, and continues to support you with your future testing goals.

Test automation and simulation

Software and hardware to define, run and analyse tests and simulations.

Power Conversion and Control

High performance power source that includes AC and/or DC output converters, 4Q power supplies, sensors and controllers.

Device Under Test (DUT)

The equipment to be tested: a converter, a battery pack, a passive load, a DC bus, etc.

Triphase Customer / Partner


With PMx, Triphase pushes the boundries of technology and performance, while maximizing flexibility and modularity. As such, PMx is suitable for a wide variety of AC and DC testing and emulation applications.

  • 4-quadrant AC and DC applications
  • 15 kW up to 2 MW
  • <0.5 ms response standard performance / < 50 us response high performance
  • AC ratings: 0-400 | 0-690 VRMS // up to 1600 ARMS/phase
  • DC: 0-650 | 0-1250 VDC // up to 1600 ADC/channel

Our PMx systems have a range of tools to generate test setpoints and scenarios locally, but are also an excellent candidate for integration in a Power Hardware In the Loop (PHIL) system, using our various digital integrations.
