An adaptable interleaved DC-DC boost converter [PDF]

2016 IEEE 16th International Conference on Environment and Electrical Engineering (EEEIC), 2016
A new topology for an interleaved boost converter is presented in this paper. The circuit is able to provide high voltage gain without the need for using a large duty cycle. Analysis showing the effect of increasing inductor winding loss in relation to duty cycle is also presented. Losses in various components are considered and analysed.

Soft-switching SiC interleaved boost converter [PDF]

2015 IEEE Applied Power Electronics Conference and Exposition (APEC), 2015
A DC-DC converter topology is presented combining the soft switching effects of the Snubber Assisted Zero Voltage and Zero Current Transition (SAZZ) topology and the increased inductor frequency of the dual interleaved boost converter with interphase transformer. The snubber capacitors and output capacitances of the main devices are discharged prior to

A Co‐Designed Implicit‐Reset Path PFD and Current Mismatch Compensated CP Enabling Sub‐0.5% Mismatch and Dead Zone‐Free for Low‐Spur PLLs

International Journal of Circuit Theory and Applications, EarlyView.
A co‐designed implicit‐reset phase‐frequency detector (PFD) and nonlinear amplifier‐assisted charge pump (CP) achieve dead zone‐free operation from 10 MHz to 4.7 GHz with < 0.5% current mismatch without calibration, enabling −80 dBc of reference spur and 0.50 ps of RMS jitter in a 180 nm of CMOS PLL.
