PEH2015

PEH2015 – Full bridge building block Rev. B / February, 2019 GENERAL DESCRIPTION These modules are designed for the low-voltage laboratory implementation of multilevel converters. Versatile power interfaces allow to easily configure the modules for both half- or full-bridge operation. The design is tailored for 19’’ rack integration with simple interconnections and direct connection to a BoomBox, or any other control platform. Direct access to the gating signals is offered using optical fiber inputs, while embedded measurement circuits provide direct analog outputs related to the capacitor voltage and one output current using galvanically-isolated sensors. The modules are well suited for any kind of PWM operation from 0 Hz to 50 kHz and current ratings up to 50 A. The main limitation being the power envelope of the heatsinks, which is limited to approximately 20 W with no airflow and about 30 W with a 1 m/s airflow. 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 compatibility with future developments and onboard data processing. TYPICAL APPLICATIONS The modules are ideally suited for the implementation of low-voltage prototypes of multilevel converters such as Modular Multilevel Converters (MMC), Cascaded H-br...
