How to Measure Power During Volt-second and Other Short Power Periods Webinar

3-Phase Power and Motors Masters Webinar Series

Join Teledyne LeCroy for this Learning Lab series on measuring high-power, three-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.

How to Measure Power During Volt-second and Other Short Power Periods

In this session (Part Four), 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.

Topics to be included:

  • Principles of defining the short power period
  • Variable-flux electric machine analysis example
  • DB-DTFC machine analysis example
  • Dynamic loss calculation during rapid acceleration of servo motor

Register for the rest of the series:

Who should attend? Inverter subsection engineers, motor/drive control system engineers, and inverter/drive systems engineers who design dynamic control and power systems that operate under highly controlled conditions.

What attendees will learn? Best in class techniques for measuring and understanding performance of and interrelationships between control and power sections.

Presenter: Stephen Murphy, Teledyne LeCroy Applications Engineer

Can't attend live? Register anyway, and we will send you the recording and slides afterward.


Pre-work recommended before attending the Learning Lab webinar

It is recommended that you download and register (at no cost) MAUI Studio prior to the start of the Learning Lab, and download LabNotebook (waveform plus setup files) .lnb files (they will be combined into one .zip file that will need extracting).

MAUI Studio

Zip file with .lnb files

>> File will be available before webinar starts

These files will allow you to load the various waveform examples shown during the Learning Lab webinar, and participate in hands-on instruction.
