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.

“…Between them some interesting proposals have been presented in order to improve efficiency of AC-DC power converters operating in light load condition [10]- [12]. In [13] the MCM boost converter has been modeled using PieceWise Affine (PWA) approximation to make the model useful in large signal analysis and encouraging results have been obtained with the use of predictive controller for the inductance current, [14], [15]. Whereas in [16] the inductor current is controlled by an inner loop strategy which is able to perform in MCM, owing to the fuzzy switching technique.…”

In this paper a Power Factor Control (PFC) for an AC-DC boost converter operating in light load condition has been presented. A Passivity-Based current control able to operate in either Continuous Conduction Mode (CCM) and in Discontinuous Conduction Mode (DCM) has been implemented. A voltage PI based control with input feedforward has been implemented in order to increase Power Factor (PF) and regulate the DC output.A current observer, suitable for both operating modes has been adopted in order to eliminate the need for expensive current sensor. The proposed Mixed Conduction Mode (MCM) control scheme has been numerically tested using a powerful software simulation platform and compared to classical CCM control scheme.

“…And the input current distortion is worsened as load reduces. In [11], a digital control scheme based on predictive current control with direct calculation of the duty ratio in CCM and DCM is proposed. A mode selection algorithm based on comparison between the actual duty ratio and the CCM duty ratio is used to determine the conduction mode of the inductor current.…”

Boost power factor correctors (PFCs) and digital average current controllers are usually designed for continuous conduction mode (CCM). However, discontinuous conduction mode (DCM) appears at light loads in the inductor current near zero crossings of the input current, resulting in input current distortion. It is caused by inaccurate average current values obtained in DCM. The inductor current goes to zero before the end of the switching period. Thus, the average is not given by sampling in the middle of the rising edge of the inductor current. In addition, the linear CCM PFC controller is unable to ensure input current shaping in DCM whereby the converter exhibits non-linear characteristic. This paper proposes a simple digital DCM control scheme for boost PFC. DCM current control is achieved with minimal changes to the CCM control structure, and is easy to implement digitally. Good input current shaping is achieved in both CCM and DCM.Index Terms-power factor correctors (PFCs), discontinuous conduction mode, input current distortion, digital DCM current control, boost PFC 978-1-4244-5287-3/10/$26.00 ©2010 IEEE
