PEB 4050 - IGBT half-bridge power module VDC Ileg,rms fsw, max 400 V 50 A 50 kHz Rev. A / March 2021 GENERAL DESCRIPTION The PEB 4050 is a half-bridge power module featuring two silicon IGBTs (i.e. one phase-leg). 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 onboard protections against over-current, over-voltage and over-temperature. As with all imperix power modules, PEB 4050 are compatible for plug-&-play connection to the imperix programmable controller B-Box RCP, but can also be used with other digital controllers. The mechanical design of the modules is tailored for integration in 19’’ rack-mountable chassis and enclosures. TYPICAL APPLICATIONS Imperix modules are perfectly suited to build up power converter prototypes of any topology, ranging from simple inverters to more complex multilevel topologies. PEB 4050 modules are tailored for applications related to the 120/210 VAC grid voltage. Also, thanks to their fast, yet soft switching characteristics, PEB 4050 modules are ideal for general-purpose applications and teaching. Typical applications include: » Buck and boost converters » Interleaved DC/DC converters » Variable-speed drives » Frequency converters » Soft-switched converters » Modular multilevel converters » etc. KEY FEATURES AND SPECIFICATIONS » Half-bridge topology (IGBT phase-leg) » Embedded 1100 µF DC bus » On-board voltage and current sensors » Over voltage/current/temperature protections » 650 V / 75 A silicon IGBTs » 400 V nominal DC bus voltage » 50 A continuous RMS current at 20 kHz » Fast and soft antiparallel diode » Speed-regulated cooling (140 W TDP) » 100 x 332 mm Eurocard form factor SIMILAR PRODUCTS Other types of half-bridge modules are available from imperix, with different voltage and current ratings as well as different semiconductor technologies: » PEB 8038 – 800 V / 38 A – Higher power » PEB 8024 – 800 V / 24 A – Faster switching Other topologies such as full-bridge modules and 3-level NPC modules are also available.

The implemented system corresponds to a DC/DC converter in buck configuration, also known as DC chopper.1 This system produces a controllable 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) Controller PEB 4050 Ib PI ÷ PWM + – VDC A L V R Fig. 2.  Topology of a buck converter using the power module 1  This example and many more are available on the imperix knowledge base. 2 ABSOL.
