“…Transformers are often madeto order, unlike the inductor in a non-isolated converter, which can be bought off the market. In an isolated design, additional parts that wouldn't be needed in a non-isolated system, like opto-couplers, may be added [2]. In comparison to a non-isolated design, all of this leads to a higher cost.…”

This paper approach for the performance analysis of a dc-dc flyback converter for low power application. Modelling is done with parasitic components for non-ideal flyback converter. Ac and dc input characteristic of the flyback converter are analysed and investigated by PSIM simulations and calculations. The influence of parasitic effects in converter components on input characteristic is studied in continuous conduction mode (CCM). The results of the calculation based on analytical formula and averaged models are in a good accordance with PSIM simulations and calculation. The goal of this project is to compare an ideal and non-ideal condition in order to see the effect on the efficiency and ability of the converter to control the output voltage. The converter is expected to be operated in continuous conduction mode at all time and focus application is low power application that less than 100W.

“…Regarding general DC-DC power converters, several reviews can be found in the literature [7,8], including DC-DC converters for very specific applications [9,10]. However, for the most part, the presented solutions use many discrete components in the implementation of the DC-DC converters, not being the most beneficial for applications as LiDAR systems.…”

LiDAR (Light Detection And Ranging) is a technology used to measure distances to objects. Internally, a LiDAR system is constituted by several components, including a power supply, which is responsible to provide the distinct voltage levels necessary for all the components. In this context, this paper presents an efficiency comparison of three different DC-DC converter architectures for a LiDAR system, each one composed of three DC-DC converters: in parallel; in cascade; and hybrid (mix of parallel and cascade). The topology of the adopted integrated DC-DC converters is the synchronous buck Switched-Mode Power Supply (SMPS), which is a modified version of the basic buck SMPS topology. Three distinct SMPSs were considered: LM5146-Q1, LM5116, and TPS548A20RVER. These SMPSs were selected according to the requirements of voltage levels, namely, 12 V, 5 V, and 3.3 V. Along the paper, the principle of operation of the SMPSs is presented, as well as the evaluation results obtained for different operating powers, allowing to establish a comprehensive efficiency comparison.

“…Os LEDs são dispositivos incapazes de controlar sua própria corrente quando acionados a partir de uma fonte de tensão, portanto necessitam de um circuito entre a fonte de energia e a carga capaz de controlar a corrente fornecida [6]. Com esse objetivo existem diversos conversores estáticos concebidos para diferentes aplicações [7]. Por exemplo, os conversores CC-CC Buck e Forward, são interessantes pois possuem característica de rebaixadores de tensão, podendo adequar um nível maior de tensão ao nível de tensão dos LEDs que normalmente é reduzido [8].…”

Este artigo detalha o procedimento de integração, incluindo projeto e simulação, de um conversor Buck-Boost atuando na correção do fator de potência (PFC) e de um conversor Forward como controlador de potência (PC). O circuito de conversores integrados é responsável por alimentar uma carga de LEDs que emitem luz de temperatura de cor distinta, possibilitando aplicações de iluminação circadiana. Resultados são mostrados a partir da análise das formas de onda utilizando o software PSIM, no qual foi observado boa correspondência entre os resultados teóricos e de simulação, validando o projeto proposto.
