- NPC building block
Rev. B / February, 2019
GENERAL DESCRIPTION
The PEN modules are designed for the implementation of low-voltage power converters. The mechanical design is tailored for 19’’ rack integration with simple interconnections and direct connection to a Boom Box, 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 optical 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 galvanically-isolated sensors.
Overvoltage, over-current and over-temperature protections are also integrated on the board for safer use in R&D applications. Besides, these protections are userprogrammable through a simple onboard microcontroller and a CPLD.
Finally, the possibility to use alternative or customized mezzanine boards enables the patibility 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, ranging from conventional three-phase three-level inverters to more plexe multilevel topologies. Typical power ratings are around 10 k W, depending on the nominal DC link voltage and the switching frequency.
