(Universidade Federal de Santa Maria, 2008-03-10)
This Ph. D. Thesis presents a in deep study of the mechanism of resonant transition soft-switching techniques. By means of the principles that rules the PWM resonant transition converters, a novel tool for analysis and ...
Análise e implementação de um circuito de auxílio à comutação integrado aplicado a uma fonte ininterrupta de energia
(Universidade Federal de Santa Maria, 2008-04-14)
This study proposes an auxiliary commutation circuit, applied to a double-conversion uninterruptible power supply, operating with a three-level PWM full-bridge inverter. In order
to construct this circuit, we use the concept ...
