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
