3-phase Power and Motors Masters Series

3-Phase Power and Motors Masters Learning Lab Series

3-phase Power and Motors Masters Webinar Series
Join Teledyne LeCroy for this Learning Lab series on measuring high-power, 3-phase and motor inverter and drive systems with an 8-channel high-resolution oscilloscope or motor drive analyzer. Learn about static and dynamic measurements, from AC line to inverter switching, and line outputs to motor mechanical performance.

All sessions are now available to watch on-demand at your convenience 24/7. Simply click the session below you're interested in and you'll be directed to the recording.

Part One: How to Measure Inverter Dead Times and Input/Output Power
In this session we will describe techniques for measuring dead-times for gate-drive signals and device outputs to ensure that margins are achieved. We will also assess input and output power of a simplified single-phase DC-AC inverter.

Part Two: How to Perform Static and Dynamic Power Analysis
In this session we will describe the differences between static and dynamic power analysis and how to optimize setup and measurement for each. Special attention will be paid to visualizing dynamic power trends and correlation of these trends back to acquired voltage and current waveforms.

Part Four: How to Measure Power During Volt-second and Other Short Power Periods
In this session we will review examples of power calculated during power periods equivalent to a device switching time. This is especially helpful for understanding instantaneous control response time, as required for deadbeat-direct torque and flux control (DB-DTFC) and other rapid response control systems.

Part Five: How to Perform AC Input and Inverter/Drive Output Harmonic Analysis
In this session we will demonstrate how to perform total harmonic distortion (THD) and harmonic analysis on variable frequency waveforms on both AC line (50 or 60 Hz) inputs and variable frequency outputs.
