“…DC-DC switch mode power converters find great amount of applications and are under steady development [1][2][3][4][5]. The considerations of this paper concern the most important group of converters based on pulse-width modulation (PWM) with constant switching frequency f S = 1/T S (T S -switching period).…”

“…Usually the averaged models of the converter power stage are used, representing relations between currents and voltages averaged over an elementary switching period. Standard methods of an averaged model derivation, namely state-space averaging and switch pair averaging are widely described in the literature, for example [1,2,[6][7][8][9]. The switch averaging approach is most commonly used and is described in many references as more convenient than state-space averaging [1, 2, 7 ,8].…”

“…O estágio interleaved é caracterizado pela presença de dois braços iguais em paralelo, cujas chaves nunca são acionadas ao mesmo tempo (cada uma fica aberta em toda a metade do ciclo de trabalho onde a outra pode estar fechada). Em teoria, isso reduz as oscilações de corrente e tensão suportadas pela pilha a combustível [25]. A Tabela 3 indica o dimensionamento teórico dos componentes dos dois conversores.…”

“…No entanto, os resultados das simulações computacionais listados na Tabela 4 evidenciam como a opção boost+buck mostra-se superior à buck-boost, tanto do ponto de vista da eficiência energética, como do ponto de vista da redução das oscilações de corrente. Esse último aspecto resulta em concordância com as informações da literatura, sendo mencionado como uma das principais vantagens da topologia interleaved [24][25]. Ambos os fatores são de extrema importância no projeto do protótipo.…”

“…Therefore, fault identification is crucial to prevent fault propagation and avoid catastrophic failures of the converter, which affect proper operation [1][2][3][4][5][6][7][8][9]. Among the components utilized in both PWM and resonant converters circuits [10,11], inductors and capacitors have the greatest impact on the converter operation because faults and aging manifest as changes in the value of the parameters out of tolerances. Moreover, parasitic inductances and capacitance are exploited inside resonant converter to achieve proper operation.…”
