If the system keeps operating and clears the fault in time, the power supply reliability of the system will be greatly improved. SVPWM is widely used in the converter. However, the SVPWM will generate third harmonic voltage in the system. Firstly, the topology of multi-terminal flexible DC transmission system including structures and grounding modes is discussed. Subsequently, a common-mode equivalent circuit mode for analyzing the influence of third harmonic voltage is established. Thirdly, the formula for calculation of the third harmonic voltage and current is derived. The fault characteristics are also analyzed and a diagnostic method of fault location is proposed. Finally, the simulation experiments are made in PSCAD/EMTDC. The simulation results show that the proposed protection strategies can accurately locate the fault line after pole-to-ground fault occurs.","PeriodicalId":230939,"journal":{"name":"2019 IEEE 4th International Future Energy Electronics Conference (IFEEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129246424","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}

First, its state space average model is built. The computation of Jacobian matrix eigenvalues reveals that Hopf bifurcation will emerge as certain circuit or control parameter varies. The simulation results in PLECS show that the bifurcation points derived by the state space model roughly correspond to those derived by the simulation. The simulation also reveals that this circuit operates in a pattern where continuous conduction mode (CCM) and discontinuous conduction mode (DCM) occur alternately when the Hopf bifurcation takes place. To fill in the gap between theoretical analysis and simulation results, the discrete iterative mapping of voltage controlled Z-source DC-DC converter is presented. Compared with the state space average model, the discrete iterative mapping can portray the slow-scale stability boundary with better precision. In addition, with consideration of the switching between CCM and DCM, a non-smooth discrete iterative mapping of the system is derived.","PeriodicalId":230939,"journal":{"name":"2019 IEEE 4th International Future Energy Electronics Conference (IFEEC)","volume":"96 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121448502","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}

Integrating GaN power transistors and their drivers in a single chip solves a number of challenges using GaN devices, which monolithically integrate all power stages to design low cost and high power density power converters. An internal regulator is generally required in such a power converter application. The regulator has a variety of functions, including a voltage source that provides a regulated voltage before the power driver starts up, and a power supply for external devices such as digital isolators for the high side driver signals. This paper presents a GaN-based linear regulator applied to power converter applications. All linear components use GaN devices as building blocks. The regulator consists of two common-source differential stages in a cascaded fashion to provide a high voltage conversion gain, as well as sufficient phase margins to reduce instability caused by rapid load transitions. The overall regulator was implemented in a GaN-on-Si process with maximum input and output voltages of 20 V and 6 V, respectively, at cost of 250 μA quiescent current. The regulator can source a maximum load current of 150 mA with the line regulation of 17 mV/V and the load regulation of 0.67 mV/mA. The maximum output voltage variation for a load current step change of 150 mA is within 400 mV. More than 65 dB PSRR above 1 MHz is achieved with the design.","PeriodicalId":230939,"journal":{"name":"2019 IEEE 4th International Future Energy Electronics Conference (IFEEC)","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115744357","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}
