LLC Resonant Converter Analysis Method: Frequency Domain and Time Domain

Yuqi Wei — Tue, 10 Sep 2024 00:00:00 -0700

In this video, two important analysis methods for LLC resonant converter, frequency domain and time domain analysis methods, are discussed. The detailed derivation process for two analysis methods are presented. It helps people understand how to perform two different analysis methods and what are the differences between these two methods. Most importantly, recommendations for using of these two methods.

Layout Priorities- Layout and Parasitics in Power Converters

Alex Hanson — Wed, 18 Sep 2024 00:00:00 -0700

This video considers where parasitics are most likely to cause problems in a power converter and how to prioritize layout to minimize those parasitics.

Commonality aspects of switched capacitor converters (SCC) and switched capacitor filters (SCF)

Shmuel (Sam) Ben-Yaakov — Wed, 18 Sep 2024 00:00:00 -0700

The operation of both switched capacitor converters (SCF) and switched capacitor filters (SCF) are shown to be dependent on the internal resistance, Re, of the switched capacitor circuit. In this presentation, the expression for the Re value is derived in an intuitive way and used to explain its pivotal importance in the SCC and SRF operations.
