This Ph. D. dissertation presents contributions to the investigation of soft-switching cells with integrated components, presenting three main approaches: (i) Soft-switching cells with filter coupled inductor; (ii) Integrated ...
Metodologia de síntese de topologias ZVT simplificadas aplicadas a pólos PWM bidirecionais
(Universidade Federal de Santa Maria, 2009-11-27)
Among the soft-switching techniques, the zero-voltage-transition (ZVT) technique has been accepted well by the industry due its attractive characteristics, such as simplicity, low losses in the auxiliary commutation circuit ...
