The impact of the recombination mechanisms in luminescent materials is discussed with regard to luminescence based gas-sensing applications and the use of semiconducting materials, as an alternative to organic–metal complexes, is outlined.

The method is derived and illustrated for an effective 2D setup first and then for 3D slab waveguide lenses. We employ slab waveguides of different thicknesses connected by curved surfaces to realize a lens-like structure. To simulate the wave propagation in 3D including reflection and scattering losses, the stepwise angular spectrum method is combined with full vectorial finite element computations for subproblems with lower complexity. Our SASM results show excellent agreement with rigorous numerical simulations of the full structures with a substantially lower computational effort and can be utilized for the simulation-based design and optimization of complex and large scale setups.","lang":"eng"}],"publication":"Optics Express","doi":"10.1364/oe.409612","volume":28,"author":[{"full_name":"Ebers, Lena","id":"40428","last_name":"Ebers","first_name":"Lena"},{"full_name":"Hammer, Manfred","id":"48077","orcid":"0000-0002-6331-9348","last_name":"Hammer","first_name":"Manfred"},{"last_name":"Förstner","orcid":"0000-0001-7059-9862","id":"158","full_name":"Förstner, Jens","first_name":"Jens"}],"date_updated":"2022-01-06T06:54:26Z","intvolume":" 28","page":"36361","citation":{"mla":"Ebers, Lena, et al. “Light Diffraction in Slab Waveguide Lenses Simulated with the Stepwise Angular Spectrum Method.” Optics Express, vol. 28, no. 24, 2020, p. 36361, doi:10.1364/oe.409612.","short":"L.

Usually, modular multilevel converters are used in high-voltage DC-applications (HVDC) in the multiple kV-range, but to meet the needs of a high-current demand at low output voltage levels, the modular converter concept requires adaptations. In the proposed concept, the MMC is used to step-down the three-phase medium-voltage of 10kV, and provide up to 1 MW to the load. Therefore, each module is extended by an LLC resonant converter to adapt to the specific electrolyzers DC-voltage range of 142 - 220V and to provide galvanic isolation. The six-arm MMC converter with half-bridge modules can be simplified and optimized by removing three arms, and thus halving the number of modules. In addition, the module voltage ripple and capacitor losses are decreased by 22% and 30% respectively. By rearranging the components of the half-bridge MMC to build a MMC consisting of grid-side full-bridge modules, the voltage ripple is further reduced by 78% and capacitor losses by 64%, while ensuring identical costs and volume for all MMCs. Finally, the LLC resonant converter is designed for the most efficient full-bridge MMC. The LLC can not operate at resonance with a fixed nominal module voltage of 770V because the output voltage is varying between 142 - 220V. By decreasing the module voltage down to 600V, additional points of operation can be operated in resonance, and the remaining are closer to resonance. The option to decrease the module voltage down to 600V, increases the number of required modules per arm from 12 to 15, which requires to balance the losses of the LLCs and the grid-side stages."}],"status":"public","_id":"29939","user_id":"34289","department":[{"_id":"52"}],"keyword":["Multilevel converters","Resonant converter","High voltage power converters","ZVS Converters","Combination MMC LLC"],"language":[{"iso":"eng"}],"publication_status":"published","year":"2020","citation":{"ieee":"R.

The wide voltage transfer ratio needs to be covered for the entire load range conventionally requiring two-stage converter architectures. Considering a less complex single-stage solution potentially enabling cost and weight advantages, traditional LLC converters are unsuitable topologies since it results in a too wide operating frequency range. Most alternative topology candidates show comparable difficulties. To overcome this issue, the gain range of the LLC with full-bridge inverter can be extended by operation in half-bridge mode for low voltage transfer ratios. Phase-shift operation is utilized for intermediate gains and low loads. This paper describes a detailed design methodology for the resonant tank. The experimental results with a peak efficiency of 96.5 % and a power density of 2.1 kW/l prove the proposed concept."}],"status":"public","type":"conference","publication":"PCIM Europe digital days 2020","language":[{"iso":"eng"}],"_id":"29896","user_id":"66","department":[{"_id":"34"},{"_id":"52"}]},{"department":[{"_id":"34"},{"_id":"52"}],"user_id":"66","_id":"29898","language":[{"iso":"eng"}],"publication":"PCIM Europe digital days 2020","type":"conference","status":"public","abstract":[{"text":"An onboard DC-DC converter connects the high voltage traction battery to the low voltage auxiliary battery of an EV. It has to provide power across a wide range of input and output voltages. This paper presents the design and evaluation of an economical two-stage converter concept consisting of a first-stage boost converter and a second-stage LLC converter. While for low input voltages, the boost converter can supply the second-stage LLC with the optimum bulk voltage, for high input voltages, the boost converter is turned off and the LLC regulates the output voltage on its own. Whereas this is unproblematic for high output currents, for low loads high switching frequencies become necessary. For this purpose, the LLC needs to be designed for a wide gain range. Traditionally, this is achieved through a small magnetizing inductance resulting in increased conduction losses. If an asymmetric duty cycle operation is used to cover the low gains at low output current, the LLC can be optimized for a better efficiency. A prototype design proves that the asymmetric duty cycle operation is feasible to achieve a wide gain range at a high efficiency whereas the conventional design achieves very poor efficiencies.","lang":"eng"}],"date_created":"2022-02-20T21:28:08Z","author":[{"last_name":"Rüschenbaum","full_name":"Rüschenbaum, Tobias","first_name":"Tobias"},{"last_name":"Rehlaender","full_name":"Rehlaender, Philipp","id":"69469","first_name":"Philipp"},{"full_name":"Ha, Phuong","last_name":"Ha","first_name":"Phuong"},{"last_name":"Grote","full_name":"Grote, Tobias","first_name":"Tobias"},{"last_name":"Schafmeister","full_name":"Schafmeister, Frank","id":"71291","first_name":"Frank"},{"first_name":"Joachim","id":"66","full_name":"Böcker, Joachim","orcid":"0000-0002-8480-7295","last_name":"Böcker"}],"date_updated":"2022-02-23T14:51:13Z","conference":{"end_date":"2020-07-08","name":"PCIM Europe digital days 2020","start_date":"2020-07-07"},"main_file_link":[{"url":"https://ieeexplore.ieee.org/document/9177998"}],"title":"Two-Stage Automotive DC-DC Converter Design with Wide Voltage-Transfer Range Utilizing Asymmetric LLC Operation","citation":{"short":"T.

The generally weak intrinsic (body) diodes of the MOSFETs cause turn-on\r\nlosses when being forced to hard current commutations finally leading to the components self-destruction when operated constantly in this way. Consequently, zero-voltage switching (ZVS) operation is more or less essential in a silicon (Si) MOSFET-based HB or FB. To ensure ZVS, the LLC is operated in the inductive region, i.e. with lagging resonant current. On the contrary, IGBTs show dominant turn-off losses\r\nand therefore are conventionally not applied in LLCs typically requiring high switching frequencies to achieve low output voltages. Yet, if the LLC is intentionally designed for the capacitive region, i. e.\r\noperation with leading current, zero-current switching (ZCS) enabling IGBTs in the inverter stage can be ensured. This paper explores in detail the LLC in the capacitive operating region and gives design considerations for a capacitive LLC utilizing both robust and cost-efficient IGBTs for an exemplary 2.2 kW\r\nautomotive on-board DC-DC converter application. The results of a loss analysis show that the LLC resonant converter can be operated well in the capacitive region. In the given case, significantly lower\r\noverall and 30 % lower inverter stage losses are achieved in the thermally relevant worst-case comparison with an inductive LLC based on Si MOSFETs.","lang":"eng"}],"department":[{"_id":"52"}],"user_id":"60223","_id":"29874","language":[{"iso":"eng"}],"ddc":["620"],"has_accepted_license":"1","citation":{"ieee":"D.
