Emerging silicon carbide (SiC) MOSFET power devices promise to displace silicon IGBTs from the majority of challenging power electronics applications by enabling superior efficiency and power density, as well as capability to operate at higher temperatures. This paper reports on the recent progress in development of 1200V SiC power MOSFETs. Two different chip sizes were fabricated and tested: 15A...
DESIGNERS of power conversion circuits are under relentless pressure to increase power density while maintaining high efficiency. Increased switching frequency is a primary path to higher power density. Prior work has shown that the use of switching frequencies in the VHF band (30 MHz-300 MHz) are a viable path to the achievement of gains in power density. A promising topology for VHF operation is...
Designers of power conversion circuits are under relentless pressure to increase power density while maintaining high efficiency. A primary path to higher power density is the use of increased switching frequency. In this paper it is argued that the use of switching frequencies in the VHF band (30 MHz-300 MHz) are a viable path to the achievement of substantive gains in power density. Evidence for...
This paper describes the construction of a thin, flat litz ribbon cable suitable for use in magnetic components such as inductors and transformers where one requires reduced AC losses compared to conventional solid conductor ribbon conductors. This conductor has the potential for ease of manufacture and low cost compared to current solutions such as a braided litz cable. Since a 1-D analysis does...
