A clean four-quadrant sinusoidal power rectifier using multistage converters for subway applications
(2005)
A special 27-level four-quadrant rectifier for subway applications is analyzed. The arrangement uses only three H-bridges per phase, common dc bus, and independent input transformers for each H-bridge. The transformers ...
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 ...
