Nevertheless, the increase of power electronics-based renewable generation can dramatically reduce the inertia of modern power systems. This issue has already challenged the control and stability of small-scale power systems. It will soon be faced by larger power systems as the trend of renewable integration continues. In view of the inertia challenge, this paper presents a comprehensive review of conventional and emerging inertia enhancement techniques. It is revealed that the inertia emulation by wind turbines has successfully demonstrated its effectiveness and will receive widespread adoptions. In addition, the virtual inertia generated by the DC-link capacitors of power converters has a great potential due to its low cost. The same concept can also be applied to ultracapacitors. Moreover, batteries will serve as an alternative inertia supplier. In future power systems where most of the generators and loads are connected via power electronics, virtual synchronous machines (VSMs) will become the main inertia provider. In general, it is concluded that advances in semiconductors and control promise to make power electronics an enabling technology for inertia control in future power systems.","PeriodicalId":446770,"journal":{"name":"2018 IEEE International Power Electronics and Application Conference and Exposition (PEAC)","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132220476","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 paper presents a switching angle generation mechanism and calculation method of sinusoidal pulse width modulation (SPWM). Combining the calculated switching angles, the numerical calculation equations based on single Fourier series is derived to perform quantitative evaluation harmonics in SPWM. The proposed method is compared with the method based on classical double Fourier series for computational complexity. The influence of modulation index on each high-order harmonic is summarized.

We use a sub-circuit based on the industry standard CMOS model BSIM3 to represent the performance of power MOSFETs. According to the analysis and comparison between logic CMOS and power transistors, some of the conventional CMOS parameters are deactivated to simplify the device characterization. Meanwhile, some special extensional settings are developed and some parameters are utilized in another method to describe the specific structure of power devices. As a basis for extended BSIM3 parameter extraction the transistor characteristics are obtained from the circuit simulation of original vendor models, i.e. measurements are replaced by flexible simulations and “black box” vendor models are translated to standard BSIM3. Extraction of the BSIM3 parameters is shown for the DC-IV forward and reverse characteristics and the modeling improvement strategy is given for the case of IV characteristics.","PeriodicalId":446770,"journal":{"name":"2018 IEEE International Power Electronics and Application Conference and Exposition (PEAC)","volume":"159 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131172127","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}

Aiming at realizing effective edge termination and avoiding premature breakdown, we propose a new fluorine-ion-based junction termination extension (F-JTE) method, which is well suited for vertical GaN devices in which the selective p-type region is difficult to form. The influences of the F-JTE and its key parameters (e.g. dose, thickness and width) on the electric field distribution and breakdown voltage have been extensively investigated and revealed by TCAD simulations. The negatively charged F-JTE region can effectively spread the electric field away from the main junction, leading to increased breakdown voltage. With a partial recess step, a double-zone JTE with a graded distribution of charges can be formed, which can further improve the breakdown voltage and process latitude.","PeriodicalId":446770,"journal":{"name":"2018 IEEE International Power Electronics and Application Conference and Exposition (PEAC)","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133635754","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}
