in this paper, a dc-dc resonant converter with high voltage gain and small size is studied. to reduce the size and weight of this converter, the operating frequency should be as high as possible. in this research, the frequency changes from 120 to 200 khz. due to the high operating frequency, it is necessary to reduce the switching losses using soft switching methods. resonant converters are su...

In this paper, the immune controller, is used to control the paralleled DC-DC converters. A PID controller is first applied and its coefficient is optimized using an intelligent (PSO) algorithm. Immune controller is then added to PID controller and an immune PID controller is formed. Two methods have been suggested to determine non-linear behavior of immune controller. In the first method, an e...

This letter addresses the problem of voltage regulation and balanced current sharing in a parallel connection heterogeneous DC-DC converters common ZIP (constant impedance, constant current, power) load. To this end, distributed dynamic control approach is developed. The proposed does not rely on load profile number active converters. describes theoretical aspects rigorous Lyapunov-based stabil...

Parallel-connected converters are commonly used in applications such as DC microgrids. The presence of multiple allows for the use interleaving technique to minimize bus ripple. Most existing methods rely on communication lines, which unsuitable distributed scenarios. This paper presents a method that requires no line. elimination lines reduces system’s complexity and cost while improving its r...

Illumination non-homogeneity is the main problem which affects dense-array CPV systems. In a previous work we theoretically showed that connecting each cell in the array to a DC–DC converter module, leads to an increase of the power transfer efficiency with respect to classical series connection. This finding is here confirmed by two experiments making use of a cells’ array, one for a certain c...
