Converters at 300 kW and higher might require paralleling of semiconductors. In this work, hard-paralleling and interleaving approaches for high power converters are compared based on cost and efficiency. A method to compare these configurations including designing the switching inductor with application specific requirements is described. Such requirements may reduce the benefit of filter size reduction that comes with the higher switching frequency of SiC converters. A tool has been developed in MATLAB to obtain valid toroidal powder core inductor designs including saturation requirements. PLECS modeling is used to quantify semiconductor losses. Experimental validation of saturation characteristics with the final selected inductor is presented. A simple method to use voltage and current data from a double pulse test setup to obtain the experimental saturation characteristics of the switching inductor is presented.","PeriodicalId":349891,"journal":{"name":"2021 IEEE Energy Conversion Congress and Exposition (ECCE)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115678085","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 proportional-integral-resonant (PIR) controller is generally employed to suppress the torque ripple and smooth the speed. Generally, the PIR controller is designed based on the internal model principle, and quasi-PIR controller is usually employed instead of the classical PIR controller due to its less sensitivity to the resonant frequency. However, the disturbance rejection ability of the quasi-PIR controller is restricted by the measurement noise. Moreover, undesired dynamics will be caused by the rapid change in speed reference and multiple resonant controllers are required for suppressing multiple torque harmonics. In this paper, a new design method of the PIR controller is introduced to show the essence of the resonant controller. Instantaneous speed observer is employed to suppress the measurement noise so that better disturbance rejection ability of quasi-PIR controller can be achieved with higher gain. To avoid the undesired dynamics, two-degree-of-freedom quasi-PIR controller is proposed by employing a tracking differentiator as the prefilter for speed reference. With the proposed TDOF quasi-PIR controller, multiple torque harmonics can be suppressed by only one resonant controller. Experimental results are shown to verify the proposed method.","PeriodicalId":349891,"journal":{"name":"2021 IEEE Energy Conversion Congress and Exposition (ECCE)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114795363","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}

A CMCD operating at HF-VHF also enables high power density and circuit integration, but suffers from multiple loss mechanisms that degrade efficiency. Operating at high frequency and high power output presents unique challenges, including parasitic switch losses and WPT coil losses. GaN FETs are the leading candidates for next generation power electronics due to their superior switching speed and power handling capability, but remain a primary factor limiting a CMCD from achieving high efficiency at higher power and higher frequency. In this paper, we investigate the losses that occur in CMCD converters and formulate an optimization procedure to maximize efficiency. This procedure is verified against a full circuit simulation within LTspice. With careful selection of design parameters, the performance of an optimized CMCD can achieve 101.9 W with 89.6% efficiency at 27.12 MHz.","PeriodicalId":349891,"journal":{"name":"2021 IEEE Energy Conversion Congress and Exposition (ECCE)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114688903","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}
