GENERAL DESCRIPTION
The PEB 8024 is a half-bridge power module featuring
two Silicon Carbide (SiC) MOSFETs. It is designed for use
as a building block for power electronic converters.
Direct access to the gating signals is offered using optical
fiber inputs, while galvanically-isolated on-board sensors
provide analog measurements related to the DC voltage
and the AC output current. The modules also provide on-
board protections against over-current, over-voltage and
over-temperature.
As with all imperix power modules, PEB 8024 are com-
patible for plug-&-play connection to the imperix pro-
grammable controller B-Box RCP, but can also be used
with other digital controllers.
The mechanical design of the modules is tailored for in-
tegration in 19’’ rack-mountable chassis and enclosures.
TYPICAL APPLICATIONS
Imperix modules are perfectly suited to build up ambi-
tious power converter prototypes of any topology, rang-
ing from single- and three-phase inverters to more com-
plex multilevel topologies.
Thanks to their ultra-fast switching characteristics and
ultra-low switching losses, PEB 8024 modules are best
implemented within high-performance and fast switch-
ing converters. They can notably be used in medium-fre-
quency, hard-switched applications up to 200kHz.
Typical applications include:
» Isolated DC/DC converters
» Medium-frequency converters
» Active filters
» Power amplifiers and emulators
» High-performance / high-speed drives

Fig. 1.  Schematic overview of the PEB 8024 module
In most use cases, several modules are assembled in or-
der to form various power converter topologies. An ex-
ternal power electronic controller, such as the B-Box RCP,
in order to generate the necessary PWM signals.
Power connections
» DC bus terminals (DC+ and DC–)
» Switching midpoint (AC terminal)
» DC bus midpoint (M, optional connection)
Signal connections
» PWM signals inputs (650 nm optical fiber receivers)
» AC current measurement (analog output, RJ45)
» DC voltage measurement (analog output, RJ45)
» Fault feedback signal (650 nm optical fiber emitter)
Auxiliary connections
» 5/12V power supply (local control and cooling fan)
» Module-to-module coordination cable (optional)
TYPICAL APPLICATION
An elementary application of the PEB 8024 power mod-
ule is shown in Fig. 2. The implemented system corre-
sponds to a DC/DC converter in buck configuration, also
known as DC chopper.1 This system produces a control-
lable voltage on the resistive load R, thanks to suitable
PWM signals applied at the input of the power module.
If desired, feedback control can be implemented in order
to improve the stability and / or dynamic performance of
the output current, voltage or power.
Thanks to the rapid implementation of power modules,
experimental validation on power electronic applications
and their control can be facilitated and accelerated.
In order to build a complete power electronic system,
several accessory products may be required, such as:
» A mounting solution (e.g. rack-mountable chassis)
» An auxiliary power supply (e.g. from the chassis)
» A PWM signals generator, or better, a fully-program-
mable digital controller such as the B-Box RCP;
» External current and / voltage sensors (optional);
» Passive components, such as inductors or filters;
» Power sources (e.g. laboratory supply, batteries, grid)
» Electric load (e.g. resistors or regenerative loads)
» Laboratory instruments (e.g. meters, probes)
