Analysis of a Resonant Transistor DC-DC Converter with Capacitive Output Filter
TLDR
In this paper, an analysis of a resonant converter which contains a capacitive-input output filter, rather than the more conventional inductor-input input filter, is presented along with design curves along with experimental data.Abstract:
Resonant dc-dc converters offer several advantages over the more conventional PWM converters. Some of these advantages include: 1) low switching losses and low transistor stresses; 2) medium speed diodes are sufficient (transistor parasitic, inverse-parallel diodes can be used, even for frequencies in the hundreds of kilohertz); and 3) ability to step the input voltage up or down. This paper presents an analysis of a resonant converter which contains a capacitive-input output filter, rather than the more conventional inductor-input output filter. The switching waveforms are derived and design curves presented along with experimental data. The results are compared to the inductor-input filter case obtained from an earlier paper.read more
