This paper proposes a high voltage ratio and low ripple interleaved boost DC-DC converter, which can be used to reduce the output voltage ripple. This converter transfers the low DC voltage of fuel cell to high DC voltage in DC link. The structure of the converter is parallel with two voltage-doublers boost converters by interleaving their output voltages to reduce the voltage ripple ratio. Bes...

Purpose – To derive an analytical model for a dc-ac-dc parallel resonant converter operating in lagging power factor mode based on the steady-state operation conditions and considering the effects of a high-frequency transformer. Design/methodology/approach – A range of published works relevant to dc-ac-dc converters and their control methods based on pulse-width-modulation technique are evalua...

In this paper, robustness of the damping injection schemes for passivity based control (PBC) of the three-phase AC/DC voltage-source (Boost type) rectifier is studied. The idea is to extend the tuning strategy for PBC that is presented in (Jeltsema and Scherpen, 2004) for DC/DC converters to three-phase AC/DC rectifiers. In the DC/DC converter case this tuning strategy leads to a PBC scheme wit...

Aims: The backbone of treatment in advanced non-small cell lung cancer is platinum-based doublet chemotherapy. We intended to compare the effectiveness of two commonly used regimens in real world practice. Methods: This single institute, parallel comparative post marketing study included 100 patients with chemo-naïve advanced (stage IIIB, IV) non-small cell lung cancer and Eastern Cooperative O...

problem adequate structure powerlists We present transformation rules to parallelize Divide-and-Conquer (DC) algorithms over powerlists. These rules convert the parallel control structure of DC into a sequential control flow, thereby making the implicit massive data parallelism in a DC scheme explicit. The results given here are illustrated by many examples including Fast Fourier Transform and ...

In this paper, a uniform quantization design method for the parallel DC-DC converter network control system (NCS) is proposed in combination with sliding mode (SMC) strategy to solve problem that performance of poor due inability process long signals time. Taking buck as an example, firstly, master-slave current sharing SM controller designed. Then, NCS containing designed uniformly quantized c...

In this paper a high frequency DC-DC converter fed by fuel cell is analyzed. The converter consists of full bridge inverter connected to full bridge rectifier through two planar transformers and parallel resonant. The mathematical model of the fuel cell is first presented and the average model of the converter is elaborated. The developed model is used to study the characteristics and dynamics ...
