In order to improve the outdoor lightning protection ability, this paper presents a simplified compact lightning protection circuit, whose lightning protection ability can reach 20KA. It also advises to add an ORing MOSFET at the output end of power system, to solve the problem of the limit-exceeding of the synchronous rectifier electric stress when the lightning current flows backward. To make the product work under a wider temperature range and with higher reliability, this paper proposes a new thermal design, in which the power shells are designed as radiation fins, thus the MOSFETs that generate heat are installed directly on the shell, then the 5G power system could be small sized and light weight, and be more convenient to install and maintain.","PeriodicalId":366207,"journal":{"name":"2017 IEEE International Telecommunications Energy Conference (INTELEC)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128286296","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}

Class E2 dc-dc converter, which is one of the converter suitable for high operating frequency is studied. Class E2 dc-dc converter composed of a Class E amplifier and Class E rectifier. the amplifier side and rectifier side of class E2 dc-dc converter can achieve ZVS and ZDS. However, it is indicated that peak switch voltage reaches approximately 3.5 times of the dc supply voltage in the amplifier side of this converter. For that reason, it leads to the increase of cost and loss because a high-voltage switching device is necessary. This paper presents a circuit dividing the switch voltage by connecting transistors of the amplifier side of class E2 dc-dc converter. Therefore, the proposed circuit can divide peak switch depending on the connected number of transistors voltage by connecting transistors in series.","PeriodicalId":366207,"journal":{"name":"2017 IEEE International Telecommunications Energy Conference (INTELEC)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117054278","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 proposes a novel LLC resonant DC-DC converter with integrated transformer. This circuit is composed of three LLC converter cells which are connected in series on the primary side and in parallel on the secondary side with interleaved control scheme. The Series Input Parallel Output (SIPO) structure enables the converter cells to share the input voltage and output current. The interleaved operation diminishes the ripple current of the output capacitor, and can reduce the size of the output capacitor. Also a reduction effect of the transformers is obtained by using the integrated transformer which independent transformers are combined into a single core. All these features make the proposed converter suitable for especially high input voltage and high output current applications to realize higher power and higher efficiency. The steady state operating principle of the converter was demonstrated. The theoretical analysis, the equivalent model and voltage gain of the converter are presented based on fundamental harmonic analysis of the converter. A prototype with 330V input and 500W output was built-up to validate the theoretical analysis.","PeriodicalId":366207,"journal":{"name":"2017 IEEE International Telecommunications Energy Conference (INTELEC)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128020235","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}

DC power distribution systems employing 380VDC as the supply voltage is one promising approach to address this problem for countries around the world developing and deploying commercial services. We demonstrated a 380VDC power distribution system interconnected with a solar power generation system in Texas, USA. The purpose of this demonstration was to show that a 380VDC power supply system saves more energy than an AC power supply system, and to show how much carbon dioxide emissions can be reduced by integrating a solar power generation system. This demonstration resulted in an approximate 17% energy reduction compared with an AC power supply system having the same level of reliability. Also, an evaluation using Data center Performance Per Energy (DPPE) as a performance index of the efficiency of data centers was carried out. The results showed that Power Usage Effectiveness (PUE), one of the sub-metrics of DPPE, improved with the 380VDC power supply system compared with the AC power supply system.","PeriodicalId":366207,"journal":{"name":"2017 IEEE International Telecommunications Energy Conference (INTELEC)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129183510","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}

Therefore, a balancing system which takes the grid stabilizing role is necessary. Depending on the time periods of the chosen sales channels, different storage systems can be used. For short and middle time spans an electrochemical system like a battery energy storage system (BESS) can be integrated into the grid. In order to investigate in which way a BESS can operate economically and which services can be offered for grid stabilization, a 5.8 MW and 5.6 MWh battery energy storage system (BESS) was designed and built. Within this contribution, the setup will be explained.
