Role of induced exchange bias in zero field spin–orbit torque magnetization switching in Pt/[Ni/Co]/PtMn

open access: yesAIP Advances, 2020
Current induced magnetization switching is of particular interest to develop non-volatile magnetic memories (MRAM). We studied spin–orbit torque (SOT) switching in a Pt/ferromagnet/antiferromagnet Pt/[Co/Ni]2/PtMn Hall cross. For the as-deposited sample,

Boost Converter with Active Snubber Network

open access: yesAdvances in Electrical and Computer Engineering, 2017
A new concept for reducing the losses in a boost converter is described. With the help of an auxiliary switch and a resonant circuit, zero-voltage switching at turn-off and zero-current switching during turn-on are achieved.

Interleaved Boost Converter with ZVT-ZCT for the Main Switches and ZCS for the Auxiliary Switch

open access: yesApplied Sciences, 2020
A soft-switching interleaved topology is presented herein and applied to the boost converter. The basic operating principle is that the main power switches are turned on at zero voltage and turned off at zero current via the same auxiliary resonant ...
