Zero-voltage switched resonant and PWM converters: design-oriented analysis and performance evaluation

Sabaté, Juan A.Virginia Tech1994

… currents which are directly proportional to the reactive energy required by the resonant tank. The comparison of the different converters is based on the reactive energy required for ZVS. The study considers resonant converters with conventional variable frequency control and with phase-shift …

Impact of ground plane serrations on radiation and impedance characteristics of a slot antenna over a conductive back plane

Young, Matthew AUniversity of Illinois at Urbana-Champaign2015

… this bandwidth reduction is due in part to reactive energy stored in parallel plate modes. The stored energy can be reduced by treating the edge of the ground plane with serrations. Our primary goal is to show the design trade-offs between bandwidth and thickness for the conductor-backed, …
