Overview:
Switched mode power supplies have become ubiquitous in electronics as they provide precise voltages at high power with very high efficiency. The efficiency of these power supplies requires low loss power transistors and the design requires measurement of highly dynamic voltages. The range of these voltages can be hundreds of volts in some applications. In this webinar, the proper use of a digital oscilloscope to accurately measure these voltages will be discussed along with key aspects of instrument performance such as noise and overdrive recovery that affect the accuracy of the measurement.

What you will learn:

  • Switched mode power supply basics
  • Typical SMPS measurements including
    • Electrical characterization (switching loss, safe operating area)
    • Input analysis (power quality, current harmonics)
    • Output analysis (line and switching ripple, spectral analysis, turn on time)
  • How to maximize voltage measurement accuracy
Presenter:
Mike Schnecker, Business Development Manager, Rohde & Schwarz
Mike Schnecker has a BS from Lehigh University and an MS from Georgia Tech, both in electrical engineering. He has 22 years of experience in the test and measurement industry in applications, sales and product development roles, and has specialized in signal integrity applications including jitter using oscilloscopes and other instruments. Prior to joining Rohde & Schwarz, Mr. Schnecker held positions at LeCroy and Tektronix. While at LeCroy, he was responsible for the deployment of the SDA series of serial data analyzers.
