In this paper we study the modeling and control of an interleaved DC-DC multilevel topology that exhibits a high-voltage gain and a minimum ripple point design. In this configuration, the current ripple cancelation point can be arbitrarily defined according to a desired specification, which represents an advantage with respect to classical topologies whose minimum ripple point is constrained (e.g...
This paper presents an analysis of the dynamics of two particular DC-DC converters that have switched-capacitors; a DC-DC Three-Switch High-Voltage Converter and a DC-DC Single-Inductor Multiplier Cuk Converter. The purpose of this paper is to explain the dynamics of the parallel connection of capacitors during the switching states of the converters. The obtained large signal models may provide a...
This work introduces a set of PWM SEPIC dc-dc converters specially designed for high voltage-gain conversion, the voltage gain in the proposed converters can be adjusted by PWM and by adding diodes and capacitors in a diode-capacitor multiplier structure. They main features are: (i) high-voltage gain, without extreme duty cycles and transformer-less which allow high switching frequency and without...
