摘要

Despite record growth rates, the global inverter market for renewable energies facesrnincreasing pressure on cost without giving in on reliability and performance. Main drivers forrnnew development are cost reduction and increased efficiency. This is particularly valid forrnmedium power Inverter up to 100kW for solar- and energy storage systems. To stay costrncompetitive, product designer must consider not only the bill of material of their products butrnalso the efficiency of the whole manufacturing process. Thus todays challenge for powerrnelectronics designer is not only to focus on a cost efficient and reliable product, but also howrnthe design can increase productivity, e.g. less required time for assembly. This paper isrngoing to address these challenges and introduce a new scalable but simple medium powerrnstack design, which guarantees maximum utilization, cost efficiency and is designed forrnmanufacturing. To underline this discussion and the theoretical considerations, this approachrnwill be proved by having a 50kW stack simulated, built and tested. The theoretical approach,rnthe design considerations as well as the measurement results will be explained andrndiscussed in this paper.
