Opportunities and Challenges in Very High Frequency Power Conversion
David J. Perreault,Jingying Hu,J.M. Rivas,Yehui Han,Olivia Leitermann,Robert C. N. Pilawa-Podgurski,Anthony D. Sagneri,Charles R. Sullivan +7 more
TL;DR: In this article, the scaling of magnetic component size with frequency is investigated, and it is shown that substantial miniaturization is possible with increased frequencies even considering material and heat transfer limitations.
Journal ArticleDOI
Resistance Compression Networks for Radio-Frequency Power Conversion
TL;DR: In this article, a new class of matching networks that greatly reduces the load sensitivity of resonant inverters and radio frequency (RF) power amplifiers is introduced, which serve to substantially decrease the variation in effective resistance seen by a tuned RF inverter as loading conditions change.
Journal ArticleDOI
A High-Frequency Resonant Inverter Topology With Low-Voltage Stress
TL;DR: In this paper, a new switched-mode resonant inverter, which is termed the inverter that is well suited to operation at very high frequencies and to rapid on/off control is presented.
Proceedings ArticleDOI
Design Considerations for Very High Frequency dc-dc Converters
J.M. Rivas,David D. Jackson,Olivia Leitermann,Anthony D. Sagneri,Yehui Han,David J. Perreault +5 more
TL;DR: In this paper, the authors describe several aspects relating to the design of dc-dc converters operating at frequencies in the VHF range (30-300 MHz) and treat the design considerations in the context of a DC-dc converter operating at a switching frequency of 100 MHz.
Proceedings ArticleDOI
A very high frequency dc-dc converter based on a class Φ 2 resonant inverter
TL;DR: In this paper, a new dc-dc converter suitable for operation at very high frequencies under on-off control is introduced, where the converter power stage is based on a resonant inverter (the Phi2 inverter) providing low switch voltage stress and fast settling time.
