Switched-Resonator Converter

The presentation covers the concept, design and operational modes of a novel switch-mode power converter developed at Ben-Gurion University, and presents experimental results of a laboratory converter that demonstrate up to 95% efficiency.

YAY! Glad to see you back on here, Sam.

can the 3rd phase be simply implemented in a half-bridge 2-stage cockcroft walton capacitive multiplier for higher efficiency, e.g. with a zener or such?

Hello Professor, Thank you for the explanation. As with some resonant converters, I was wondering if the switching frequency is changed for load and line variations to accommodate zero voltage switching.

@0:52 Doesn't a transformer satisfy those equations?

Shmuel, I happy to see your returning to the audience!!! You remember, I like to dig (sometimes off to the side :) In the case with this gyrator, I dug out the old good gyrator, described in the book of Erickson and Maksimovic. It is also resonant and uses a diode bridge as shown in Fig. 4.1 here
From the point of view of waveforms, the output current in the presentation is a rectified version of the inductor current in Fig. 4.34(a), page 31.
