DC Power Electronics Training System (8010-6)

The DC Power Electronics Training System provides a comprehensive study of the diode and switching transistor, two semiconductor components that are widely used in power electronics circuits. It also provides in-depth coverage of various types of chopper, a power electronics device used in many dc power circuits (e.g., dc motor drives, battery chargers, dc-to-dc converters, etc.). The training system equipment mainly consists of the IBGT Chopper/Inverter, Model 8837-B, and the Four-Quadrant Dynamometer/Power Supply, Model 8960-2. The IBGT Chopper/Inverter consists of insulated-gate bipolar transistors (IGBT) and diodes used to build various types of choppers. The Four-Quadrant Dynamometer/ Power Supply is a highly versatile module used in the DC Power Electronics course as a voltage source and battery charger. The operation of these modules is controlled via the LVDAC-EMS software, which also provides the instrumentation required to measure and record the experimental data.

Features & Benefits

  • The training system teaches the principles of dc power electronics, as well as the operation of various dc power electronics devices, through clear, easy-to-follow theory presentations and simple, demonstrative hands-on exercises.
  • The course curriculum of the Electric Power Technology Training Program is highly flexible and allows a multitude of different customized training solutions.
  • The courseware includes student manuals and instructor guides with all the theory required to perform the hands-on experiments.
  • All workstations, modules, and components are very sturdy to ensure a prolonged service life in a demanding environment such as a training laboratory.
  • The modular design approach of the training equipment allows a large variety of courses to be performed using a small number of modules, without unnecessary duplication of equipment.
  • All electrical components can be interconnected without electric shock hazard since all live parts of the connection leads are concealed and insulated.
  • All electrical symbols representing the components used in a laboratory exercise are clearly silk-screened on the front panel of the modules.
  • The training system includes two highly versatile USB peripherals:
    • Four-Quadrant Dynamometer/Power Supply, Model 8960-2. This module is used as a dc power source and a battery charger/discharger with a large variety of configurable parameters. The module can also be used as an overnight battery float charger.
    • Data Acquisition and Control Interface, Model 9063. This module gives access to a large variety of computer-based measuring instruments and is used to control the various dc power electronics devices. Both of these functions are implemented via the LVDAC-EMS software.
  • Software upgrades for LVDAC-EMS and firmware upgrades for the Four-Quadrant Dynamometer/Power Supply and Data Acquisition and Control Interface are available for download free of charge on the Festo Didactic website.
