Interactive Lab Assistant: Self-commutated converter circuits 1kW

This instruction manual makes up an Interactive Lab Assistant course. This multimedia course guides you step-by-step through the aspects of modern self-commutated power converter circuits. The fundamentals are conveyed using easily understood animations. Interactive Lab Assistant, combined with virtual instruments for controlling the hardware, provides a very user-friendly experiment platform.

Features:

• Interactive experiment set-ups
• Measurements and graphics can be saved within the experiment instructions by means of drag and drop
• Virtual instruments can be started directly from the experiment instruction pages themselves
• Questions with feedback and evaluation logic for checking student progress
• Print-compatible document for comfortable printing of experiment instructions with solutions
• Labsoft browser, course software and virtual instruments

Training contents:

• Fundamentals of IGBTs
