Webinar: Hybrid-Resonant Switched Capacitor Converters (April 28)

A free 45 min. talk followed by Q&A.

Abstract: Power management and delivery continue to be a technical bottleneck in a number of applications that demand high efficiency at the ever-decreasing physical size. Hybrid switched-capacitor (SC) converters, which combine switched-capacitor stages with an inductor or inductive impedance have gained traction in recent years to address stricter size/performance tradeoffs. This talk will provide an introduction to hybrid-resonant SC topologies and outline their advantages in terms of active- and passive-component utilization, the ultimate arbiter of efficiency and power density. Conventional and recently published topologies will be discussed and compared using a general framework to illustrate various strengths and weaknesses. Additional challenges related to gate driving, control, capacitor balancing, and startup will be explored as they related to performance, reliability, and the commercial viability of these topologies.
