Seminar Overview

The School of Measurement sessions will be presented by technical experts from Rohde & Schwarz, and focus on real-world design challenges in power electronics while offering participants an opportunity for hands-on interaction.

 

Power electronics encompasses a wide range of applications, from small power converters in low-power applications to large-scale electric power generation and transmission systems. The School of Measurement concept will introduce participants to the principles of power electronics applications that require a basic to advanced understanding of power conversion systems in modern power-electronics applications as they replace conventional power electronics designs.

 

Combining theory with practice at the in-person sessions, electronics engineers can use the latest R&S®MXO 4 series oscilloscopes from Rohde & Schwarz under everyday testing conditions on actual DUT applications. To address a broad audience across Europe, the sessions will highlight different exercises such as DC/DC and AC/DC conversion, control loops, filter responses, EMI debugging, basic FFT and protocol decoding, component characterization, efficiency measurements and calculation of losses, as well as power and PWM signal analysis.

Attendees will rotate between sessions/demo stations: 
 

Session 1:

Get to know a way to measure if the DC-DC converter corresponds to the local electronics/emissions standards and regulations.

  • Analysis of frequency harmonics
  • Conducted emissions
  • Effect of the input filter
  • Near field radiated emissions
  • Identify and correlate sources of EMI

 

Session 2:

Measure main parameters of a step-down DC-DC converter. Identify the power losses per component, and see this in relation to the efficiency of the converter.

  • Base parameters
  • Switching characteristics of the converter
  • Transient response
  • Start-up, Power losses & Efficiency

 

Session 3:

Analyze the behavior of a PFC boost converter across its different stages. Verify the harmonics and power quality at the input stage.

  • Input harmonics
  • Power quality, Ripple
  • Switching analysis:

Zero-crossing detection, PWM signals, Stages of boost PFC

 

Session 4:

Study and experiment testing of BLDC and PMDC motors, and their different power conversion stages.
