XC - The technology powering our solutions

XC is a control and networking technology dedicated to power electronic applications. XC significantly reduces setup and development time for new power conversion system architectures.

As such, it enables the user to focus on new, innovative applications while improving reliability, efficiency and cost.

XC Overview

XC is at the core of every Triphase solution. It offers a straightforward method to quickly setup customized power electronic systems. The network takes care of data stream distribution and synchronization between an arbitrary number of sensors and actuators, and the control unit.

On the control unit, multiple software processes can access the data streams to and from various nodes in the system. All proccess data can be logged in real-time on hard disk for analysis (both during operation and during/after system faults)

Triphase offers its own control units, XC network interfaces for 3rd-party control units, turn-key power modules for AC and DC conversion, interfacing cards for 3rd-party stacks, voltage and current measurements and sensor interfaces for 3rd-party sensors.

XC-enabled components

Control Units

Our Real-time Targets (RTT) are powerful, multi-core PC-based units equipped with a real-time Linux/Xenomai-based operating system. For the RTT user, controlling actuators and accessing measurement streams is as simple as opening and writing files in Linux. The XC network card handles communication, synchronization, organization and logging of data streams in the background. This allows for advanced control action and signal processing both in real-time and non real-time. Measurement streams can be processed on a sample-by-sample basis or in batches both on- and off-line.

We also offers XC network cards for select 3rd-party control units.

Power Modules

Our PMx modules are ready to use power modules for AC/DC and DC/DC conversion and motor control applications. A power module contains one or more sets of power stacks, sensors and configurable output filters and is packed in an industrial grade enclosure with automated start/stop and emergency circuitry and air cooling. Triphase PMx modules are designed for flexibility and ease of use. PMx modules are bidirectional and ideal for connecting multiple sources and loads with eachother.

PMx modules come with high-performance voltage, current and motor drive software.

Inverter Stacks

Triphase offers a range of 3rd-party, industrial, of the shelf inverter stacks from different vendors, equipped with an XC interface. A inverter stack is an assembly of power semiconductors, gate drivers, cooling and optionally measurements. With the XC interface users can directly control the PWM dutycycles and collect the measurements over the network in real-time.

When multiple inverter stacks are connected, they are synchronized with nano-second presicion by the XC network.


XC sensors are high-speed, real-time AC and DC current and voltage measurements. Measurements can be synchronized with the PWM duty cycly, allowing averaged measurements over one switching cycle (e.g. for dead-time measurements). Each sensor converts the analog measured value do a digital delta-sigma stream. These streams are then sent to the XC control unit over the network.

We make our own voltage and current sensors, and also offers a range of interfaces to 3rd-party sensors (LEM, HBM, speed sensors, etc.)

XC Control Engineering

For application development, Triphase adheres to proven, easy-to-use engineering environments and open source standards:

Control Engineering

Matlab/SimulinkTM for developing real-time control algorithms


Python for test automation and automated data processing

User Interfaces

HTML5 for browser-based user interfaces

We also offer open source templates to promptly realize common power conversion applications such as bidirectional AC and DC voltage and current sources and motor controls for induction motors and PMSMs.

Short Iterative Development Cycle

XC External Communication

On a higher level, the RTT can interface through a variety of communication protocols in order to interface with your existing simulation, automation and testing infrastructure.


Digital, real-time integration with Opal-RT, RTDS, NI, Speedgoat for straightforward setup of Power Hardware In the Loop (PHIL) scenarios.


Support for a wide variety of fieldbuses and protocols (including: CAN, UDP, MODBUS/TCP, EtherCAT, TCP/IP) for easy integration with third-party automation systems.
