Análise e metodologia de projeto de conversores cc-cc isolados com comutação sob tensão nula: ponte-completa e duplo meia-ponte
(Universidade Federal de Santa MariaBrasilEngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia ElétricaCentro de Tecnologia, 2017-08-10)
This work presents a study of an isolated DC-DC converter with zero-voltage switching (ZVS)
and phase-shifted (PS) applied to full-bridge (ZVS-PS-FB) and double half-bridge converters
(ZVS-PS-DHB). The double half-bridge ...
The ZVS-PWM commutation cell applied to the DC-AC converter
(1997-12-01)
This paper presents the analysis of a dc-ac converter using a zero-voltage-switching (ZVS) commutation cell. First, we show the cell applied to the buck converter. The stages of operation are presented along with the main ...
A new family of zero-current-switching PWM converters and a novel HPF-ZCS-PWM boost rectifier
(Institute of Electrical and Electronics Engineers (IEEE), 1999-01-01)
A new family of direct current (DC) to DC converters based on a zero current switching pulse width modulated (ZCS-PWM) soft commutation cell is presented. This ZCS-PWM cell is consists of two transistors, two diodes, two ...

Boundary Control of Full-Bridge ZVS: Natural Switching Surface for Transient and Steady-State Operation
(Institute of Electrical and Electronics Engineers, 2014-02)
This paper presents the use of a high-performance boundary controller for the full-bridge zero-voltage-switching topology. An enhanced dynamic response is obtained by employing the natural switching surface (SS), which is ...
Novel zero-current-switching PWM step down Sepic converter
(1998-01-01)
This paper presents a new step down PWM (pulse width modulation) Sepic (single ended primary inductance converter) converter, featuring soft commutation at zero-current (ZCS), using IGBTs (insulated gate bipolar transistors) ...
