This paper analyzes the impact of converter design elements on the operating performance of DC/DC converters, used worldwide for renewable energy sources. The design of inductor and capacitor elements is made considering the acceptable output ripple of voltage and current. This paper presents the methodology for determining the inductances and capacitances required for DC/DC converter operation within...
A mixed switched-capacitor cell is proposed by integrating a voltage divider with a voltage multiplier. It is inserted in a boost stage for achieving a converter with high conversion ratio, low voltage stress on switches, non-pulsating input current as required as front-end to electrical grids supplied by renewable energy sources. The generalization of the proposed cell allows to achieve an ultra-high...
In this paper, a novel soft switched high frequency AC link converter is proposed for use as a battery utility interface. The proposed configuration uses 10 bidirectional switches interfacing with an AC link consisting of an inductor and a parallel capacitance. The capacitance produces soft turn off in all operating conditions, and turn on always occurs with zero voltage. This converter has several...
