Research of an Interleaved Low-Voltage/High-Current DC-DC Converter

Wang Ping,Sun Xu,Song Liangyu

Strategic Study of CAE 2005, Volume 7, Issue 4,   Pages 59-63

Abstract:

In the recent years, the operating voltages of most high-performance microprocessors were lower thanthat of the previous ones and the research of low-voltage/high-current DC-DC converter was enhanced.Among all topologies, the current-doublers topology is optional.In the current-doublers topology, the ripple current of the output filter capacitor is reduced becausethat a few of current-doublers are interleaved.

A comprehensive simulator for assessing the reliability of a photovoltaic panel peak power tracking system

Nabil KAHOUL,Mourad HOUABES,Ammar NEÇAIBIA

Frontiers in Energy 2015, Volume 9, Issue 2,   Pages 170-179 doi: 10.1007/s11708-015-0353-y

Abstract: When designing a maximum power point tracking (MPPT) algorithm, it is often difficult to correctly predict, before field testing, the behavior of this MPPT under varying solar irradiation on photovoltaic (PV) panels. A solution to this problem is to design a maximum power point trackers simulator of a PV system used to test MPPT algorithms. This simulator must have the same role as the MPPT card of the PV panel and thus will fully emulate the response of a real MPPT card of the PV panel. Therefore, it is a good substitute to help to test the peak power trackers of the PV system in the laboratory. This paper describes a simple peak power trackers simulator of the PV system which has a short response time thus, can be used to test MPPT algorithms under very rapid variation condition. The obtained results and the theoretical operation confirm the reliability and the superior performance of the proposed model.
