Description

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.
