In order to generate the aforementioned pulses, in this paper, a modular high-voltage pulse generator (HVPG) based on cascaded full-bridge sub-modules (FB-SMs) and transformer-based charging is proposed. By utilizing transformer-based charging, the need for a complex balancing circuit with numerous sensors is eliminated and all capacitors are charged incessantly via an uninterruptible charging circuit. The proposed topology has a high boosting gain and is able to charge all capacitors from a low-voltage dc input through the use of an inverter, transformer network, and voltage multiplier circuits. The FB-SMs can provide bipolar and variable voltage pulses, as well as modularity, both benefiting the efficient and cost-effective generation of plasma.The operation principle and the modulation strategy of the proposed HVPG is analyzed and verified by the simulation results using PLECS software.","PeriodicalId":151155,"journal":{"name":"2023 11th International Conference on Power Electronics and ECCE Asia (ICPE 2023 - ECCE Asia)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127208407","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 also reduces losses, and with the smaller size, the power factor of the ICTs can be much higher than that of the inductor.

However, during freewheeling period, the output current flows through high-voltage-rated diodes, resulting in large conduction loss. Also, the converter should be designed with a small magnetizing inductance to achieve zero-voltage switching (ZVS) for the lagging-leg switches, resulting in increased transformer loss. This article proposes a modified PSFB converter to mitigate the drawbacks of the conventional CIR PSFB converter. By employing two diodes in the secondary side, the output current is transferred to the primary side during the freewheeling period, facilitating ZVS for the lagging-leg switches. Moreover, the output current during the freewheeling period flows through the low-voltage-rated diodes. Therefore, the proposed converter achieves high efficiency. The performance of the proposed converter was verified using prototypes with 320–400-V input and 56-V/700-W output specifications.","PeriodicalId":151155,"journal":{"name":"2023 11th International Conference on Power Electronics and ECCE Asia (ICPE 2023 - ECCE Asia)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130589899","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}

This removes the need for large filter capacitors in the DC bus and the reliability is improved. Meanwhile, the multi-winding (zig-zag) transformer in the conventional cascaded H-bridge motor drive system can also be removed because of the high frequency transformer included in the quad-active-bridge DC/DC converter.
