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 ...

Static converter: didactic support software
(1994-01-01)
Teaching a course of special electric loads in a continuing education program to power engineers is a difficult task because they are not familiarized with switching topology circuits. Normally, in a typical program, many ...
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 ...
New 12kW three-phase 18-pulse high power factor AC-DC converter with regulated output voltage for rectifier units
(1999-12-01)
This work presents a new high power factor three-phase rectifier based on a Y-connected differential autotransformer with reduced kVA and 18-pulse input current followed by three DC-DC boost converters. The topology provides ...
