This paper provides an insight for reducing the SHC in two-stage single-phase converter from the perspective of the dc-bus port-impedance characterization. It is found that the dc-dc converters in the two-stage single-phase converter can be categorized into two types. One is operating as a bus-voltage-controlled converter (BVCC) whose dc-bus port-impedance is approximately inverse-proportional to the voltage loop gain. The other is operating as a bus-current-controlled converter (BCCC) whose dc-bus port-impedance is a negative resistor. Based on the dc-bus port-impedance characterization, critical points for SHC reduction are summarized, indicating that, for reducing SHC in BVCC, proper control scheme needs be incorporated for increasing the dc-bus port-impedance at twice the input frequency $(2f_{text{in}})$ or output frequency $(2f_{mathrm{o}});$ concurrently, the dc bus voltage ripple should be limited for reducing the SHC in the dc source or load; by contrast, for reducing SHC in BCCC, the dc bus voltage ripple should be reduced; simultaneously, the loop gain at $2fi_{text{in}}$ or $2f_{mathrm{o}}$ should be high enough for eliminating the SHC in the dc source or load. Thereafter, proper SHC reduction approaches are recommended for different types of two-stage single-phase converters, and pros and cons of different SHC reduction schemes are carefully reviewed. Finally, potential challenges and issues related to this research topic are discussed.","PeriodicalId":415217,"journal":{"name":"2018 IEEE Energy Conversion Congress and Exposition (ECCE)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125352271","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 analysis reveals that the state block diagram presented in the literature does not correctly represent the hand-code implementation of the structure that is presented in that same literature. As a result, the block diagram does not correctly model ELSO dynamic behavior. Here, a discussion of some common errors in discrete observer modeling are presented and used to correct the ELSO state block diagram. These common errors include: 1) failing to model the inherent delay present in the feedback path of all discrete state-filter and observer structures, 2) incorrectly modeling the difference equation index shifts that exist in nearly all observer structures, and 3) improper signal nomenclature for the observer predicted states. In this paper, the ELSO block diagram and code implementation from the literature is reviewed and the modeling errors are exposed. Finally, correction of these modeling errors is presented. The discrete modeling techniques presented in this paper are applicable to all discrete state-filters and observers.","PeriodicalId":415217,"journal":{"name":"2018 IEEE Energy Conversion Congress and Exposition (ECCE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115153662","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}
