Power converter efficiency is always a hot topic for switch mode power supplies. Nowadays, high efficiency is required over a wide load range, e.g., 20%, 50% and 100% load. Computer-aided design optimization is developed in this research work, to optimize off-line power converter efficiency from light load to full load. A two-stage optimization method to optimize power converter efficiency from light load to full load is proposed. The optimization procedure first breaks the converter design variables into many switching frequency branches. In each fixed switching frequency branch, the optimal designs for 20%, 50% and 100% load are derived separately in the first stage, and an objective function using the optimization results in the first stage is formed in the second stage to consider optimizing efficiency at 20%, 50% and 100% load. Component efficiency models are also established to serve as the objective functions of optimizations. Prototypes 400V to 12V/25A 300W two-FET forward converters are built to verify the optimization results.

“…After that and by means of (6) the time constant τ 10 will be known in each load step. Taking into account that this dynamic model is based in an R-L network, the time constant τ 10 can be expressed as (7). Using (7) and the set of R L (i fc ) values previously calculated, a different value of inductance L(i fc ) will be obtained for each load current step.…”

One of the power sources with most potential is fuel cells, especially in on-board applications. The design of a power distribution architecture based on fuel cells for transport applications is a complex task, due to the number and nature of the power converters, loads, secondary energy sources, etc. Modeling and simulation are essential design tools at system level. This paper proposes a complete fuel cell black box model, in order to reproduce the behavior of a commercial fuel cell with overshooted transient response. The model is parameterized by applying an identification methodology based on manufacturer's datasheets and a test based on load steps. The fuel cell black-box model is validated experimentally using a commercial PEM (Proton Exchange Membrane) fuel cell.

“…The structure of the converter is simple: only one power switch. The theoretical duty cycle of the power switch can be adjusted from 0 to 1, so the voltage gain can be infinite [8], [9]. However, due to the presence of parasitic elements in the circuit, the voltage gain is limited [10], [11].…”
