PEN8018 – NPC building block
Rev. B / February, 2019
GENERAL DESCRIPTION
The PEN modules are designed for the implementa-
tion of low-voltage power converters. The mechani-
cal design is tailored for 19’’ rack integration with simple
interconnections and direct connection to a BoomBox,
or any other control platform.
Each modules contains a NPC cell, corresponding to four
power switches and two diodes.
Direct access to the gating signals is offered using opti-
cal fiber inputs, while embedded measurement circuits
provide direct analog outputs related to one of the half
DC link voltages and the AC output current using gal-
vanically-isolated sensors.
Overvoltage, over-current and over-temperature pro-
tections are also integrated on the board for safer use
in R&D applications. Besides, these protections are user-
programmable through a simple onboard microcon-
troller and a CPLD.
Finally, the possibility to use alternative or customized
mezzanine boards enables the compatibility with future
developments and onboard data processing.
TYPICAL APPLICATIONS
The modules are ideally suited to build up ambitious
prototypes of low-voltage NPC power converters, ran-
ging from conventional three-phase three-level inver-
ters to more complexe multilevel topologies. Typical
power ratings are around 10 kW, depending on the
nominal DC link voltage and the switching frequency.

1  The maximum DC bus voltage is defined by the spec-
ifications of the bus capacitors. Therefore, as for any
aluminium electrolytic capacitors, few short-term
overvoltages can be tolerated, provided that they
involve limited amounts of energy.
2  In cold conditions, the maximum operating current is
limited by the power semiconductors. Otherwise, the
current rating of the module is limited by the power
envelope of the cooler (about 40 W with airflow).
3The maximum ripple current is defined by the equiva-
lent series resistance (ESR) of the capacitors and relates
to Joule losses and lifetime considerations. Therefore,
this value can be exceeded, provided that the operat-
ing temperature of the capacitors remains low.
4  The 12 V supply is entirely independent from the mod-
ule and serves only to supply the cooling fan.

tion of the BoomBox control platform and will feature
bidirectional Gigabit Ethernet-class communication
with the central controller. Besides, the board also
embeds an Artix 7 FPGA and a high-end microcon-
troller. This mezzanine will be publicly released simul-

hardware.

MAIN FEATURES
Connections
The power connections are located on top of the mod-
ule, using M3 screw terminals, as shown in Fig. 4. This
authorizes an easy reconfiguration of the topology,
while guaranteeing robust mechanical contacts.
Voltage measurement selector
The module embeds two distinct voltage sensors, mea-
suring the voltage on each of the half DC busses. The
user can select either of these measurements to be
wired to the analog output of the mezzanine. When
