Shifting PA in class E mode enabled to achieve anode efficiency of 88…93%. At the same time it led to a result that control and screen grid dissipated power in tetrode became one of the main factors hindering further improvement of PA characteristics. This problem can be solved by applying to the control and screen grids multilevel voltage with a certain parameters. It enables to increase either the anode efficiency or the output power. The examples of suggested grid voltage shapes and related to them PA characteristics are provided.","PeriodicalId":231207,"journal":{"name":"2016 International Conference on Actual Problems of Electron Devices Engineering (APEDE)","volume":"97 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133237273","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 tower is equipped with the information and measuring apparatus for the detection of emergency conditions. The principle of the diagnostic system is based on recording changes in the electromagnetic field around the line and tower during emergency conditions. It should be noted the ability to transfer power that exceeds the ampacity of the line as well as the risk of icing on the line elements that leads to breakage of wires are the main factors that threaten the normal functioning of the OHLs. Thereby it is proposed to create a «smart» tower containing both electromagnetic field sensors, mechanical loads and the current climate regime.","PeriodicalId":231207,"journal":{"name":"2016 International Conference on Actual Problems of Electron Devices Engineering (APEDE)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125888139","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}

In this paper, a model of two coupled gyrotron oscillators is developed and basic properties of the phase locking are studied. Time delay of the coupling signal traveling between two gyrotrons strongly affects the pattern of phase-locking regimes. The model is described by two delay-differential equations (DDEs). Domains of in-phase and anti-phase synchronization are calculated.
