We record for the first time the species Pelecinus polyturator (Drury, 1773) in the Ceará state, Brazil. Most specimens were collected in March, the peak of the rainy season in the humid mountain ranges. In addition, digital images of the P. polyturator and a map with the geographical distribution of the species are presented.
The use of FPGA for development of digital control strategies for power electronics applications has shown a growing interest of many researchers. The advantages offered by FPGA include lower design effort, high performance and highly flexible prototyping. This paper proposes a unified one-cycle controller for boost PFC based on FPGA. This controller can be applied to a total of twelve converters, six inverters and six rectifiers defined by four single phase VSI topologies and three voltage modulation types. The project was developed with the tools of Altera ® Quartus ® II. The proposal is validated by simulation and experimental results.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
