“…For the lowered power delivery, the efficiency of the original solution was higher, but on the other hand, it must be stated here that the switching frequency was 5 times lower. In principle, presented experimental measurements declare that with the use of optimized inductive components, it is possible to improve efficiency together with power density as well [20][21][22] When analyzing the efficiency results of an optimized coil converter made with an unevenly distributed shortened air gap, it is clear that the efficiency of the PFC converter with these coils was lower than expected, which probably resulted in increased lossesincrease in core volume but also due to increased current ripple [3,20]. This could be due to the effect of the aluminum heatsink, which was close to the coils (Figure 16), reducing their inductance.…”

PFC Inductor Design Considering Suppression of the Negative Effects of Fringing Flux

In this paper, the main aim of the study was the investigation of the possibilities of power inductor design, reflecting the performance of the component itself, as well as the operational efficiency of the power factor correction (PFC) converter. PFC inductors represent a key component of the converter, while within the design of any magnetic component, several design rules must be considered to provide proper operational performance. Here we discuss skin-effect, while the proximity effect and formation of fringing flux pose a more serious problem in terms of mitigating their negative impact. Therefore, in this study, the space is devoted exclusively to the analysis of the impact of the fringing flux of the PFC inductor and subsequently to the possibilities of its suppression. The resulting optimizations are reflected in the investigation of the operational efficiency of the PFC converter.

“…Regarding current ripples, they influence the effective value of current of the output capacitor, what affects its lifetime. Therefore, analyses according to current ripples must be provided if the optimized operation of the converter is the target [22][23][24].…”

In this article, the practical comparison of the operational performance of the modular (or multiport) and non-modular bidirectional buck/boost (bi-BB) DC/DC converter is realized. The main contribution of the work is the evaluation of both concepts based on various aspects, considering the qualitative indicators of the systems relevant for microgrids. Here, we discuss efficiency, electrical properties, costs, and component values. At the same time, critical comparisons are provided for converters based on SiC and GaN technology (non-modular high-voltage SiC-based dual-interleaved converter and modular low-voltage GaN-based). The concepts are specific with their operating frequency, whereby for each solution, the switching frequency is different and directly influences relevant components. The efficiency, overall system volume, output voltage ripple, and input current ripple are compared mutually between both concepts with a dependency on power delivery. These factors, together with overall volume and costs, are very important considering modern converters for microgrid systems. The summary of pros and cons is realized for each of the proposed converters, whereby the evaluation criterion is reflected within the electrical properties targeting microgrid application.

In this paper a practical and original solution for a mild-hybrid traction system is proposed. It is based on a surface permanent magnet (SPM) synchronous motor drive supplied by a three-level active neutral point clamped (NPC) inverter and a bidirectional half-bridge interleaved converter on the battery side. Design issues, optimization (especially from the efficiency point-of-view) and advantages of the considered system architecture are analyzed through simulation and preliminary experimental results. A prototype hybrid traction test bench controlled by multiple digital signal controllers is proposed
