However, the output regulation of IPT system is of great complexity with maintaining soft-switching operation by conventional methods. In this paper, an inductive power transfer system for battery charging applications are proposed to achieve output regulation by only secondary-side control without the wireless communication. Besides, the proposed system can realize soft-switching on the primary-side to further reduce the power loss and the EMI issues. The system operates at a constant switching frequency and by a monotonic output regulation to maintain a high stability during the power conversion. The circuit operation analysis, proposed output regulation method and the hardware implementation are analyzed. In order to verify the proposed system, a 1 kW IPT prototype is built and its peak efficiency achieve 96.8% at 330 V/ 3 A output.","PeriodicalId":171455,"journal":{"name":"2020 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130927268","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 structure of converter is as similar with conventional multi point clamped (MPC) multilevel converter (MLC) topologies, such as Diode Clamped Converter (DCC), Flying Capacitor Converter etc.. However, there is no need of additional devises to clamp intermediate DC link voltages. Therefore, the proposed conversion system is more compact and cost effective. In addition, The required standing voltage across power semiconductor devices which are used in the proposed topology is minimum thereby, the efficiency of the system is high. The real time large scale system parameters are used to validate the performance in software platform.

It is hard to calculate the AC resistance which increases depending on the frequency because of skin and proximity effect. Hence the relationship between laminated bus bar geometry and its AC resistance is visualized to realize the design of AC resistance. Besides, it is shown that the terminal geometry, where the capacitor and power devices are connected, affects AC resistance components. The damped oscillation waveform, which is one of the causes of electromagnetic noise, under switching operations will occur under high-speed switching operation. In this case, the oscillation frequency depends on the parasitic parameters of the converter circuit geometry, and it is normally over 10 MHz. This paper presents that AC resistance considering the bus bar and terminal geometry, and it makes damping factor larger than that of only DC resistance to suppress the damped oscillation level. In this paper damped oscillation of drain-source voltage of SiC-MOSFET is simulated and experimented using buck converter circuit, rated at 500 V and 30 A.","PeriodicalId":171455,"journal":{"name":"2020 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":"476 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133608384","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 inverters are generally switched to the current limiting mode to limit the fault currents when short-circuit faults happen. However, the fault currents will be distorted seriously due to the zero-current clamping effect as analyzed in this paper. In order to limit fault currents and suppress the fault current distortion, this paper presents a novel current limiting method. In the proposed method, the hardware current limiting circuit and the software current limiting scheme can immediately limit fault currents in cooperation. The switching frequency switchover strategy can effectively mitigate the fault current distortion. The purpose of the method is to prevent power devices from being damaged, and to ensure breakers to reliably operate and effectively support the subsequent relay protection.

This implementation technique only involves few logic comparisons and arithmetic operations, so the code size and execution time are reduced by approximately 40 percent. Moreover, it achieves significantly lower neutral-point voltage ripple compared to the conventional three-level space vector modulation method for a wide range of modulation indices and load power factor values. The validity of the proposed modulation technique is verified using Opal-RT Hardware-in-the-Loop (HIL) simulation.
