Review of Architectures Based on Partial Power Processing for DC-DC Applications

Abstract: This paper presents a review of advanced architectures based on the partial power processing concept, whose main objective is to achieve a reduction of the power processed by the converter. If the power processed by the converter is decreased, the power losses generated by the power converter are reduced, obtaining lower sized converters and higher system efficiencies. Through the review 3 different partial power processing strategies are distinguished: Differential Power Converters, Partial Power Converters a… Show more

“…Furthermore, maintaining the same efficiency for the power converter, the global efficiency of the system increases. The literature around PPP presents different strategies that achieve a reduction of the total power processed by the converter [23]. On one side, differential power converters (DPC) can be found, whose main objective is to correct current unbalances between series connected elements.…”

“…High efficiency is achieved by means of partial power processing as well as by coordinating the operation of the interleaved channels of the converter. Reference [13] presented a review of advanced architectures based on the partial power processing concept, and three different partial power processing strategies including differential partial power converters and mixed strategies are distinguished in this paper. Reference [14] analyzed different PPC topologies and connection configurations to increase the efficiency of the DC/DC stage in two-stage PV energy systems, and further elaborated three solutions for pratical PV systems based on a new proposed PPC topology.…”

“…Nos últimos anos, diversos trabalhos têm sido desenvolvidos com o intuito de melhorar o desempenho do estágio CC-CC empregado em sistemas FV descentralizados conectados à rede elétrica, cujos conversores CC-CC normalmente são dispostos em cascata com os módulos FV e o barramento CC. Neste caso, toda a potência ativa transferida da entrada para a saída é processada pelos conversores CC-CC [2]- [4]. São trabalhos que abordam o dimensionamento das arquiteturas FV [5], [6], a escolha e projeto dos conversores [3], [7], [8], o rastreamento do ponto de máxima potência (MPPT, do inglês maximum power point tracking) [9]- [11], etc.…”

“…No contexto atual da eletrônica de potência, uma abordagem que ganhou destaque na literatura para aplicação principalmente em sistemas FV diz respeito ao processamento parcial de potência (PPP, do inglês partial power processing), cuja concepção permite que somente uma fração da potência ativa total seja processada pelos conversores do estágio CC-CC [2]. Em outras palavras, o PPP consiste em permitir que somente uma pequena parte da potência ativa total do sistema FV (P FV ) seja processada, enquanto a maior parte da potência ativa transferida do sistema FV para a saída não é processada [5], [12].…”
