Constant frequency resonant topologies for bidirectional DC/DC power conversion
Proceedings of IEEE Power Electronics Specialist Conference - PESC '93, 2002The use of unidirectional constant frequency (CF) DC-DC power converter families based on quasi-resonant, quasi-square-wave (QSW), and multi-resonant topologies for bidirectional power conversion is proposed. The complete analysis and design considerations for bidirectional buck/boost CF-ZVS-QSW power converters are discussed in terms of switching and ...

Resonant DC-DC converter for high efficiency bidirectional power conversion
2013 Twenty-Eighth Annual IEEE Applied Power Electronics Conference and Exposition (APEC), 2013For achieving the high gain characteristics of LLC resonant converters in both of the power flow directions for bidirectional power transfer applications, a bidirectional LLC resonant converter with auxiliary switches is proposed. Auxiliary switches are connected in the primary and secondary sides of the proposed converter, respectively.

Single-cycle resonant bidirectional DC/DC power conversion
Proceedings Eighth Annual Applied Power Electronics Conference and Exposition,, 2002Two new families of bidirectional DC/DC converters suitable for high frequency high efficiency operation are proposed, based on single-cycle resonant (SCyR) topology. The ZCS/ZVS and ZVS/ZCS-SCyR bidirectional converter families are capable of resonant operation from no-load to full-load, and they have load independent PWM-like characteristics ...

Bidirectional DC/DC power conversion using quasi-resonant topology
PESC `92 Record. 23rd Annual IEEE Power Electronics Specialists Conference, 2003A family of zero-current-switching/zero-voltage-switching and zero-voltage-switching/zero-current-switching quasi-resonant bidirectional DC/DC converters suitable for high-frequency operation based on a bidirectional quasi-resonant switch is proposed. These converters are realizable with only two power MOSFETs.

Electrodeposited Nanolaminated CoNiFe Cores for Ultracompact DC–DC Power Conversion
IEEE Transactions on Power Electronics, 2015Laminated metallic alloy cores (i.e., alternating layers of thin film metallic alloy and insulating material) of appropriate lamination thickness enable suppression of eddy current losses at high frequencies. Magnetic cores comprised of many such laminations yield substantial overall magnetic volume, thereby enabling high-power operation.
