This new step-down topology features a static conversion ratio that makes it suitable in applications requiring an output voltage slightly lower than the input voltage. A dc analysis is performed, the static characteristics are derived and the design equations are provided in detail. The device stresses are evaluated and compared to other buck topologies revealing its superiority regarding several features. Compared to a classical buck, the static conversion ratio at the same duty cycle D is higher. It is shown that the proposed converter exhibits excellent efficiency over a wide range of the duty cycle. The theoretical analysis of the converter is accurately confirmed by simulation and experiments. The measurements proved the feasibility of the proposed step down quadratic converter.","PeriodicalId":349940,"journal":{"name":"2021 IEEE 19th International Power Electronics and Motion Control Conference (PEMC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131720249","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}

The proposed approach utilizes a reverse-engineering method to estimate the frequency-dependent characteristics of the cable materials.

Then the material specifications of the cable PVC are estimated in the FEA software. The results verify that the the proposed model can predict the CM impedance of the cable with a great accuracy in a wide frequency range. This approach is highly practical and convenient, which can be readily extended to different kinds of power cables, ensuring high accuracy at a wide frequency range.","PeriodicalId":349940,"journal":{"name":"2021 IEEE 19th International Power Electronics and Motion Control Conference (PEMC)","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131279931","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}

The proposed converter is used for short-term auxiliary power supply to the electric motor drive inverter from a battery energy storage system. The series resonant converter features simple implementation and high power density due to the high efficiency achieved by soft-switching. Due to the relatively large converter current, a multiphase, i.e., three-phase interleaved, topology was used. The disadvantage of this topology is the unequal sharing of the load current among the phases. Current imbalance between the phases can lead to unacceptable component current stress and cause a reduction in system efficiency and reliability. In this work, a simulation model has been developed to study the effect of resonant component tolerances on current imbalance between the three phases of the proposed converter. Measurements on the physical model confirmed the results of the simulation experiment.","PeriodicalId":349940,"journal":{"name":"2021 IEEE 19th International Power Electronics and Motion Control Conference (PEMC)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126859583","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}

The benefits of the design results from the elimination of external heat-sink, and resonant inductor as well as an increase of capacitance of the switched capacitor by parasitic capacitance. It allows for reduction of the number of connectors, mechanical parts, and switched capacitors. The implementation of the converter becomes significantly simplified, which is demonstrated in this paper, where the required parameters are achieved by the use of multilayer PCB. Furthermore, the converter composed of an air-based resonant choke, high temperature switches, diodes, capacitors and PCB material allows for its operation in high ambient temperature or with high temperature increment. The paper demonstrates the design concept and the achieved parameters of the converter which reaches 97% of efficiency, 700 Watt of the output power and 9,33 W/dm3 power density. Heat distribution in the converter is analyzed in two cases of ambient temperature. It is demonstrated that the concept is favorable for operation at a higher temperature of ambient.","PeriodicalId":349940,"journal":{"name":"2021 IEEE 19th International Power Electronics and Motion Control Conference (PEMC)","volume":"113 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116944559","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}

The inverter bases on a T-type topology with an auxiliary circuit which reduces turn-off switching losses. The solution can be especially favorable in high power IGBT-based converters where the achieved reduction of the turn-off losses can be substantial. The auxiliary circuits reduce pace of the voltage rise by discharging of a snubber capacitor during turning the half-bridge switches off. The paper presents operation principle of the S3L converter, its control and efficiency under the active and reactive load as well as control scheme improvement at part load operation. The proposed special control protects the converter against shorting the snubber capacitors which can occur when the load current is not high enough. The possibility of the dead-time cancelation is demonstrated as well. The analysis is underpinned with experimental results based on a 33 kVA demonstrator.","PeriodicalId":349940,"journal":{"name":"2021 IEEE 19th International Power Electronics and Motion Control Conference (PEMC)","volume":"130 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121559877","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}

In such applications, compensation may be excluded from the receiver in order to minimize it. If transmitter compensation is also simplified, series-none (SN) compensation topology is created. It was recently shown that classical first harmonic approximation (FHA)based analysis fails to accurately predict RMS values of system currents, thus overestimating the achievable coil-to-coil efficiency. Consequently, this paper establishes modified FHA(MFHA) equivalent circuit of SNcompensated inductive power transfer link (IWPTL) utilizing analytical expressions of primary and secondary currents based on time-domain differential equations (DE) based solution. It is shown that the outcomes of proposed MFHA and DE methods are very close, justifying the proposed methodology.
