  abstract     = {{Automotive DC-DC converters linking the traction battery to the auxiliary battery are characterized by the wide input and output voltage ranges resulting from the varying state-of-charge of the traction and auxiliary battery. 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.}},

  abstract     = {{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.}},

  abstract     = {{LLC resonant converters generally employ MOSFETs in the inverter stage, which can be of half-bridge
(HB) or full-bridge (FB) type. The generally weak intrinsic (body) diodes of the MOSFETs cause turn-on
losses 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
and 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.
operation 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
automotive 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
overall and 30 % lower inverter stage losses are achieved in the thermally relevant worst-case comparison with an inductive LLC based on Si MOSFETs.}},

  abstract     = {{Micro- and smart grids (MSG) play an important role both for integrating
renewable energy sources in conventional electricity grids and for providing
power supply in remote areas. Modern MSGs are largely driven by power
electronic converters due to their high efficiency and flexibility.
Nevertheless, controlling MSGs is a challenging task due to highest
requirements on energy availability, safety and voltage quality within a wide
range of different MSG topologies. This results in a high demand for
comprehensive testing of new control concepts during their development phase
and comparisons with the state of the art in order to ensure their feasibility.
This applies in particular to data-driven control approaches from the field of
reinforcement learning (RL), whose stability and operating behavior can hardly
be evaluated a priori. Therefore, the OpenModelica Microgrid Gym (OMG) package,
an open-source software toolbox for the simulation and control optimization of
MSGs, is proposed. It is capable of modeling and simulating arbitrary MSG
topologies and offers a Python-based interface for plug \& play controller
testing. In particular, the standardized OpenAI Gym interface allows for easy
RL-based controller integration. Besides the presentation of the OMG toolbox,
application examples are highlighted including safe Bayesian optimization for
low-level controller tuning.}},
