Power Electronics Training System



The Power Electronics Training System combines a modular design approach with computer-based data acquisition and control to provide unrivaled training in power electronics to students already having a sound knowledge of basic electric power technology. The system features the Four-Quadrant Dynamometer/Power Supply, Model 8960, and the Data Acquisition and Control Interface, Model 9063, two state-of-the-art USB peripherals that greatly enhance the learning experience of students.

Training begins with the following four courses:

• DC Power Electronics

• Single-Phase AC Power Electronics

• Three-Phase AC Power Electronics

• Thyristor Power Electronics

These courses introduce the student to the most common power electronic components (power diode, thyristor, and power transistor) as well as to many power electronic devices used in numerous applications today (power diode single-phase and three-phase rectifiers, choppers, single-phase and three-phase inverters, thyristor single-phase and three-phase bridges, solid-state relays or SSRs, and thyristor ac power controllers). Training continues with the following three courses which deal with common industrial applications using power electronics:

• DC Motor Drives

• Three-Phase Motor Drives

• Three-Phase Induction Motor Starters

The following two courses from the Electric Power Technology Training Program, can be optionally added to the Power Electronics Training System to enhance student training in power electronic applications:

• Hydropower Electricity Generation

• High-Voltage DC Transmission Systems

These two courses familiarize the student with the use of hydropower to produce electrical power using synchronous generators, as well as with the transmission of large amounts of electrical power using high-voltage, direct-current (HVDC) lines, two advanced applications using thyristor power electronics.

Features & Benefits

  • The training system teaches the principles of dc and ac power electronics. To this end, students follow a complete curriculum that includes these topics:
    • Courses that cover the operation of various power electronics devices, both dc and ac, as well as single-phase and three-phase.
    • Courses that cover a variety of common power electronics applications, such as dc motor drives, three-phase motor drives, and three-phase induction motor starters.
    • Optional courses that cover advanced applications of power electronics, such as hydropower electricity generation, and HVDC transmission systems.
  • All control of power electronics devices is computerized via the LVDAC-EMS software, allowing for user-friendly operation, high configurability, and ease of monitoring.
  • Video presentations of several power electronics control functions used in the training system are available on Youtube.

  • 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. It 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. All functions are implemented via the LVDAC-EMS software.
  • The training system also includes three highly versatile power electronics modules controlled using the Data Acquisition and Control Interface:
    • IGBT Chopper/Inverter, Model 8837-B. This module is used to implement various types of choppers and inverters.
    • Power Thyristors, Model 8841. This module is used to implement various thyristor-based devices (e.g., bridges, ac power controllres, solid-state relays)
    • Rectifier and Filtering Capacitors, Model 8842-A. This module is used to implement various types of power diode rectifiers.
  • 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.
