A New Asymmetrical Current-fed Converter with Voltage Lifting

open access: yesAdvances in Electrical and Computer Engineering, 2011
This paper presents a new zero voltage switching current-fed DC-DC converter with high voltage gain. In this converter all switches (main and auxiliary) turn on under zero voltage switching and turn off under almost zero voltage switching due to snubber

Autotuning of Resonant Switched-Capacitor Converters for Zero Voltage Switching

open access: yes2023 IEEE 24th Workshop on Control and Modeling for Power Electronics (COMPEL), 2023
By operating resonant switched-capacitor converters at resonance, zero current switching (ZCS) can be achieved to eliminate voltage-current overlap losses. Previous literature has shown that zero voltage switching (ZVS) can also be achieved to further reduce switching losses and attain a higher peak efficiency by recovering the charge stored in the ...
