Abstract Energy harvesting from photovoltaic (PV) strings is significantly affected by partial shading. To address this problem, several power‐electronics‐based methods have been proposed in the literature. In this context, this letter presents a

Abstract When dealing with power factor correction (PFC) rectifiers that require the use of high filter capacitances, conventional small‐signal modelling techniques are not capable of reproducing the converter behaviour accurately owing to the impa

This work is mainly concerned with the improved photoelectrothermal (IPET) modeling of an extra-high current (EHC) and extra-high luminous flux (up to 60 klm) solid-state light source based on a chip-on-board (COB) light-emitting diode (LED). The stu

This work presents the analysis of a high power factor power supply operating at high switching frequency. An almost unity input power factor is obtained when an interleaved Boost-Flyback converter associated with a nondissipative snubber is used as

Air conditioners deserve special attention, because they represent a significant part of the power system load, mainly in high temperature regions. This work takes into account conventional air conditioners, and also variable-speed arrangements with
