As such DC-DC converters, LLC resonant converters have been attracting attention. However, the LLC resonant converter generates a large resonance voltage at the resonator, so the resonance inductor and resonance capacitor must be large in size. Recently, a previous study proposed a secondary-side resonance LLC converter to reduce the resonant voltages of the passive components. Nevertheless, this LLC converter requires a resonant capacitor in parallel with the rectifier to achieve boost mode operation, which complicates the circuit operation and design. Therefore, we have considered the use of the magnetizing inductance of the coupled transformer of the current doubler rectifier as a method to realize the boost mode operation. In this paper, we propose a new method of boost mode operation for LLC resonant converter using secondary-side resonance and the current doubler rectifier.","PeriodicalId":175972,"journal":{"name":"2022 IEEE 7th Southern Power Electronics Conference (SPEC)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125278139","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Different degradation modes, e.g., fatigue of solder and thermal interface layer, influence the phase of the thermal impedance frequency response function $angle boldsymbol{Z}_{text{th}}(j omega)$ at specific bandwidths. Thus, tracking changes of the phase between periodic device-loss excitation at specific frequencies and the resulting junction temperature response allows identifying these degradation modes. This is exploited by the proposed method for degradation diagnosis. The method excites periodic conduction losses at selected frequencies via small-signal manipulation of the gate-source voltage and measures the phase delay between gate-source and drain-source voltage. The measurable phase delay results partially from the dynamic response of the thermal impedance, because the phase-delayed junction temperature impacts the on-state resistance and therefore the drain-source voltage. Conse-quently, changes of the measurable phase delay allow identifying changes of $angle Z_{text{th}}(jomega)$ and thus diagnosing the above mentioned degradation modes. The paper features a detailed analysis of the proposed method as well as an effective excitation and extraction circuit that allows phase delay measurements with high resolution over multiple frequency decades. Experiments with silicon carbide MOSFETs demonstrate that the implemented method can effectively diagnose changes of the thermal path between the device and the coolant that result from different degradation modes.","PeriodicalId":175972,"journal":{"name":"2022 IEEE 7th Southern Power Electronics Conference (SPEC)","volume":"15 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124471192","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An integrated co-optimisation model for sizing and energy management is proposed to minimise the levelised cost of electricity (LCOE) and dump load ratio (DLR), while maximising the reliability of power supply. Parasitism predation algorithm is employed to solve the multi-objective optimisation problem. Moreover, a repair-based penalty approach is integrated for effective constraint handling. The Westray Island standalone microgrid in Scotland is considered as a case study. Annual hourly weather data and demand profile of Westray Island are used to simulate the system in MATLAB environment. Results show that the WEC acts as an energy buffer in the microgrid with about 6% higher LCOE and 85% higher reliability of the power supply compared to the case without WEC integration. It also demonstrates that the diesel generator plays a minor role in the microgrid with WEC, which further reduces emissions. However, with the WEC integration, the DLR has increased by 124%, compared to the case without WEC.","PeriodicalId":175972,"journal":{"name":"2022 IEEE 7th Southern Power Electronics Conference (SPEC)","volume":"110 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124250456","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
