Conducted EMI Yield by Static Converters Applied to Power Factor CorrectionThis paper investigates the conducted electromagnetic interference (EMI) yielded by power converters used power factor correction.The topologies discussed in this paper are the boost, interleaved boost and dual boost converters. An analysis of the conducted noise behavior of differential mode and common mode in the converters are presented. All converters are designed in a way that the total harmonic distortion of the input current are same, in order to use the same input filter. It is presented the EMI filter design in order to adapt the converters as the standard of electromagnetic interference, CISPR. Experimental results of converters operating in power factor correction for a load of 300W is presented, as well as, experimental results of EMI analyzing the impact of the use of EMI filter, the alteration of the gate resistance of the semiconductor switches and changed in the configuration of the inductor boost for dual boost topology. RESUMOEste trabalho investiga a interferência eletromagnética (EMI) conduzida gerada por conversores estáticos aplicados a correção do fator de potência. As topologias discutidas neste artigo são os conversores boost, boost intercalado e dual boost. Uma análise do comportamento dos ruídos conduzidos de modo diferencial e de modo comum nos conversores são apresentados. Os conversores são projetados de forma que a taxa de distorção harmônica da corrente de entrada seja a mesma, com o objetivo de usar o mesmo filtro de EMI de entrada. É apresentado o projeto do filtro de EMI com o objetivo de adequar os conversores a norma de interferencia eletromagnética (CISPR 22). Resultados experimentais dos conversores operando na correçao do fator de potência para uma carga de 300W são apresentados, bem como, resultados experimentais de EMI analisando-se o impacto da utilização do filtro de EMI, da alteração da resistência de gate das chaves semicondutoras e alteração da configuração do indutor boost na topologia dual boost.

“…The adaptive-frequency-optimization (AFO) controller adjusts the DC-DC converter's switching frequency while tracking the converter's minimum input power (maximum efficiency) point under variable operation conditions of the power converter. A design methodology to define the input current ripple and the switching frequency required to minimize the volume of filters and heat sinks using different methods to reduce the switching losses has been described in [6]. An increase of the switching frequency reduced the boost inductor volume, but required a bulky EMI filter to operate according to the required standards.…”

In space qualified DC-DC converters, optimization of the following electrical characteristics is of greater interest in comparison with other specifications; power loss/efficiency, output voltage ripple and volume/weight. The main goal of this paper is to present an appropriate solution for optimizing the above mentioned characteristics. For this purpose, a comprehensive power loss model of a DC-DC converter is fully developed. Proper models are also demonstrated for assessment of the output voltage ripple and the utilized transformer volume as the bulkiest component in a DC-DC converter. In order to provide a test bed for evaluation of the proposed models, a 50W push-pull DC-DC converter is designed and implemented. Finally, a novel cost function with three assigned weight functions is proposed in order to have a trade-off among the power loss, the output voltage ripple and the utilized transformer volume of the converter. The cost function is optimized for applications in which volume has the highest priority in comparison with power loss and ripple. The optimization results show that the transformer volume can be decreased by up to 51% and this result is verified by experimental results. The developed models and algorithms in this paper can be used for other DC-DC converter topologies with some minor modifications.

“…With the increasing of the switching frequency, the switching losses also increase, and in addition, there is the increase of the losses generated by diode reverse recovery current. The heat sink volume is responsible for about 60% by the converter total volume on hard switching with MOSFET [1,5]. These high power losses hamper the converter operation at high frequencies.…”

“…When the boost switch turns on, the recovery reverse charge, which is stored in diode rectifier, creates a large current spike that increases losses in both the switch and rectifier [5]. As result, their applications in higher power and higher frequency are limited.…”

The optimized static converter design is directly related to the appropriate choice of operation point (Δi @ fs). The magnetic elements like inductor and noise filter, and thermal elements like heat sink are which main influences in the converter volume. These elements are strongly influenced by the chosen operation point, showing a direct relationship among them [1]. With the increase of both the switching frequency and the input current ripple occurs reduction of the inductor volume. On the other hand, it increases the switching losses into semiconductors and influence on the EMI filter volume.However, the switching losses can be minimized using auxiliary commutation circuits, which reduce the power dissipation over the main semiconductor devices, decreasing the heat sinks volume.This works presents a comparative analysis, aiming to find the operation point that the converter figures out the minimum final volume applied to different semiconductor technologies and auxiliary commutation circuits.
