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.","lang":"eng"}],"citation":{"ama":"Rehlaender P, Grote T, Tikhonov S, Mario S, Schafmeister F, Böcker J.

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"}]},{"has_accepted_license":"1","date_updated":"2022-02-23T16:12:56Z","conference":{"location":"Nürnberg","start_date":"2020-07-07","name":"Power Conversion and Intelligent Motion (PCIM)","end_date":"2020-07-08"},"author":[{"id":"60223","full_name":"Urbaneck, Daniel","last_name":"Urbaneck","first_name":"Daniel"},{"full_name":"Rehlaender, Philipp","first_name":"Philipp","last_name":"Rehlaender","id":"69469"},{"full_name":"Schafmeister, Frank","first_name":"Frank","last_name":"Schafmeister","id":"71291"},{"full_name":"Böcker, Joachim","orcid":" https://orcid.org/0000-0002-8480-7295","last_name":"Böcker","first_name":"Joachim","id":"66"}],"year":"2020","status":"public","title":"LLC Converter Design in Capacitive Operation utilizes ZCS for IGBTs – a Concept Study for a 2.2 kW Automotive DC-DC Stage","ddc":["620"],"user_id":"60223","_id":"29874","language":[{"iso":"eng"}],"main_file_link":[{"url":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=9178220"}],"abstract":[{"lang":"eng","text":"LLC resonant converters generally employ MOSFETs in the inverter stage, which can be of half-bridge\r\n(HB) or full-bridge (FB) type. 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.

Three recent classes of attacks exploit weak cipher modes (EFAIL Malleability Gadgets, or EFAIL-MG), the flexibility of the MIME email structure (EFAIL Direct Exfiltration, or EFAIL-DE), and the Reply action of the email client (REPLY attacks). Although all three break message confidentiality by using standardized email features, only EFAIL-MG has been mitigated in IETF standards with the introduction of AEAD algorithms. So far, no uniform and reliable countermeasures have been adopted by email clients to prevent EFAIL-DE and REPLY attacks. Instead, email clients implement a variety of different ad-hoc countermeasures which are only partially effective, cause interoperability problems, and fragment the secure email ecosystem.We present the first generic countermeasure against both REPLY and EFAIL-DE attacks by checking the decryption context including SMTP headers and MIME structure during decryption. The decryption context is encoded into a string DC and used as Associated Data (AD) in the AEAD encryption. Thus the proposed solution seamlessly extends the EFAIL-MG countermeasures. The decryption context changes whenever an attacker alters the email source code in a critical way, for example, if the attacker changes the MIME structure or adds a new Reply-To header. The proposed solution does not cause any interoperability problems and legacy emails can still be decrypted. We evaluate our approach by implementing the decryption contexts in Thunderbird/Enigmail and by verifying their correct functionality after the email has been transported over all major email providers, including Gmail and iCloud Mail."}],"date_created":"2021-10-04T18:58:37Z","department":[{"_id":"632"}],"keyword":["decryption contexts","EFAIL","OpenPGP","S/MIME","AEAD"],"type":"conference","publication_identifier":{"isbn":["9781450370899"]},"author":[{"first_name":"Jörg","last_name":"Schwenk","full_name":"Schwenk, Jörg"},{"full_name":"Brinkmann, Marcus","first_name":"Marcus","last_name":"Brinkmann"},{"full_name":"Poddebniak, Damian","first_name":"Damian","last_name":"Poddebniak"},{"full_name":"Müller, Jens","last_name":"Müller","first_name":"Jens"},{"first_name":"Juraj","orcid":"0000-0002-3593-7720","last_name":"Somorovsky","full_name":"Somorovsky, Juraj","id":"83504"},{"full_name":"Schinzel, Sebastian","first_name":"Sebastian","last_name":"Schinzel"}],"title":"Mitigation of Attacks on Email End-to-End Encryption","year":"2020","date_updated":"2022-08-03T09:57:27Z","publication_status":"published","series_title":"CCS '20","language":[{"iso":"eng"}],"doi":"10.1145/3372297.3417878"}]
