Power inverter modules

Building blocks for modular power converters

Imperix power modules are building blocks for the rapid implementation of power inverter prototypes, as well as all sorts of power converters. They are notably ideally suited for modular power converter topologies.

The power inverter modules are designed for use inside research laboratories, in order to facilitate the rapid prototyping and validation of various converter control techniques.

Accelerating control testing

The implementation of power converter prototypes is often required in research laboratories in order to experimentally validate developments that have been previously conducted in simulation or hardware-in-the-loop simulation. This notably allows testing converter software and the related control algorithms in realistic conditions.

To this end, imperix power inverter modules can be a great help. Being ready-to-use modules, they can be quickly assembled to form all types of power converters. Besides, they offer plug-&-play compatibility with our rapid control prototyping system.

Implementing various power converters

Our power modules are designed for both teaching and research applications within power electronics laboratories. They can ideally support control software testing for industrial power inverters, or simply illustrate basic converter control techniques within an educational context.

In all cases, thanks to the various internal structures of the modules, there are practically no limitations to the range of applications that can be covered with the power inverter modules.

Inverter modules are available using either IGBT or MOSFET semiconductors.

Rapid Control Prototyping Example

Plug-&-play three-phase inverter

By combining imperix products with dedicated control software development solutions, users can easily build all sorts of power inverters, rectifiers, DC/DC converters, or matrix converters.

In this example, a three-phase power inverter is implemented using three inverter modules (phase-legs). Additional current and voltage sensors are also used for the measurements that are not provided by the power inverter modules directly.

On the other hand, the converter control is developed and tested thanks to the rapid prototyping controller, directly from Simulink or PLECS.

Inverter modules for laboratory developments

Hardware integration options

Imperix power inverter modules are best assembled within rack-mountable frames or enclosures. This guarantees the highest flexibility, thanks to the modular nature of the power modules.

Flexible rack-mountable chassis (3U)

For those who appreciate the corresponding ease of use, imperix can provide pre-assembled chassis with power supplies and various other features. This way, development modules remain easily accessible and can be easily put in (or taken out) of the chassis, hence facilitating topology alterations.

Fully-integrated enclosure (4U)

When an elegant integration of the modules is important, the power inverter modules can also be placed within rack-mountable enclosures.  This also guarantees that no dangerous voltage can ever be reached, except using 4mm laboratory safety plugs. In 4U enclosures, an LCD screen displays modules status information as well as internal temperatures.

All-in-one inverter (1.5U)

In the specific case of two-level three-phase inverters, the topology covers such a wide range of applications that modularity and reusability of the equipment are not necessarily a concern. Instead, a compact all-in-one solution is more compelling, as it minimizes wiring efforts and can achieve superior EMC performances. The TPI8032 offers a 22kW inverter power stage, including passive filters, relays, voltage/current sensors, and a B-Board PRO embedded controller.
