The reduced harmonic currents help the PHIL simulator to operate in a wider variety of interface filter conditions. However, the simulation results of FCF using the LPF are not constant and vary with the interface filter, DUT (Device Under Test) and PHIL simulator switching frequency. To make the simulation results constant, this paper proposes a digital filter to replace the LPF and a modified interface algorithm. The proposed digital filter based on integral average can remove the harmonic currents of specific frequency. The output harmonic voltages of PHIL simulator due to the input harmonic currents are not generated. Hence, the simulation results are constant regardless of the DUT and PHIL simulator switching frequency. The proposed interface algorithm injects the harmonic voltage of DUT output in PHIL simulator output voltage. Because the harmonic current outputs of DUT are able to be controlled by the amplitude of the injected harmonic voltages, the proposed interface algorithm can obtain the constant simulation results regardless of the interface conditions. Several experimental results are presented to verify the usefulness of the proposed digital filter and interface algorithm. Also, the switching frequency conditions of DUT and PHIL simulator for the proposed interface algorithm to operate effectively are check experimentally.","PeriodicalId":192132,"journal":{"name":"2020 IEEE PELS Workshop on Emerging Technologies: Wireless Power Transfer (WoW)","volume":"644 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122698379","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 conductive thread which has high electrical resistance is utilized for a receiver (Rx) coil in a clothing to generate high temperature with low current. We introduced series-none (SN) topology to eliminate a resonant capacitor in the wearable heater. The proposed wearable heaters are totally washable thanks to its non-metallic materials other than conductive threads on the clothing. Single resonant capacitor in a transmitter (Tx) is implemented for resonating both Tx and Rx, resulted in the increased power delivered to the load (PDL) while maintaining a high-power transfer efficiency (PTE) comparable with a conventional series-series (SS) topology. When supply voltage of power amplifier, VDD, is 7 V, while the PTE of SS mode and SN mode was 85.2% and 75.8% respectively, the PDL of SS mode and SN mode was 2.74 W and 4.6 W respectively.","PeriodicalId":192132,"journal":{"name":"2020 IEEE PELS Workshop on Emerging Technologies: Wireless Power Transfer (WoW)","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124438447","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}

It induces high conductive electromagnetic interference (EMI) which travels along with the capacitive coupling. To reduce the EMI emission from the wireless charger, a WPT system with a spread spectrum technique (SST) is proposed in this paper for the EV charging application. The proposed wireless charger can reduce the peak and quasi-peak values of the EMI by spreading them into wide bandwidth. Moreover, it adopts the bridgeless rectifier at the secondary side, which can control the output voltage even though its operating frequency changes due to the SST. The performance of the proposed wireless charger including the output voltage regulation and EMI reduction capabilities are evaluated using simulation results based on PSIM software.","PeriodicalId":192132,"journal":{"name":"2020 IEEE PELS Workshop on Emerging Technologies: Wireless Power Transfer (WoW)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125584359","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 PS-PWM scheme is one of the modulation schemes for CHMI and it generates same power loss such as switching loss and conduction loss on each cell. However, the PS-PWM scheme leads to the most switching loss than the other schemes for CHMI. Because the switching loss causes failure of power semiconductor switch, it should reduce for reliability of CHMI. In this paper, it is compared and discussed that total harmonic distortion (THD) of modulation methods based on PS-PWM scheme for reducing switching loss.
