Why Use The Refined Model Of Current-Loop Converter Control?

Focus:

If you’ve read through the author’s seven-part series on modeling of current-loop control, but are still not sure how how to apply Feucht’s refined model to your power supply designs, this “sequel” may help. In this piece, the author reviews the inadequecies of Spice-style circuit simulation and why math-based control-loop modeling such as that using waveform-based models can be advantageous when designing a power converter. The author reviews the similarities and differences between the existing models of current-loop control and his refined model, and concludes by noting the circumstances under which use of his refined model will more accurately predict converter performance.

What you’ll learn:

• How to understand the benefits of using Feucht's refined model of current-loop control in power converter design
