An equivalent circuit is proposed, and its parameters are derived from the oscillograms. Equivalent electrical circuits of electrostatic discharges provide a realistic way to simulate discharges and to perform controlled laboratory tests. The equivalent circuit concept also gives an analytic expression of the discharge current, and thus it is possible to calculate and estimate the charge transfer integral i dt and the heat pulse integral i/sup 2/ dt. These results are highly valuable for risk assessment of both the incenditivity (i.e. dust and gas explosions) and the damage electrostatic discharges might cause to electronic devices.<<ETX>>","PeriodicalId":185839,"journal":{"name":"Conference Record of the 1990 IEEE Industry Applications Society Annual Meeting","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123756022","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 advantages of the optimal trajectory control over the existing methods are reduced stresses on the reactive and power semiconductor switching elements of the circuit and faster responses in cases of large variations of circuit operating conditions without affecting the global stability of the system. The method is based upon the graphical representation of state variables in the phase plane. The trajectory of switching points is imposed on the phase plane by the control law. This control strategy is consequently realized by controlling a quantity of energy in the resonant circuit. The simulation results in the dynamic state are analyzed under various operating conditions and experimentally verified using an SRC prototype.<<ETX>>","PeriodicalId":185839,"journal":{"name":"Conference Record of the 1990 IEEE Industry Applications Society Annual Meeting","volume":"73 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134037483","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}

Swine vesicular disease virus (SVDV) and equine herpes virus-1 (EHV-1) were used in the experiment. Pulsed high voltage was applied repetitively to the converged electric field type electrode, which had an insulating plate with pinholes between parallel-plate electrodes. A pulsed high electric field was formed at the pinhole through which the virus suspension was continuously transported. SVDV in deionized water or in bovine serum could be inactivated effectively when the pulsed electric field (crest value of 30 kV/cm, exponential-decay waveform) was applied 60 to 120 times. or the input electrical energy was 43.6 to 87.2 cal/cm/sup 3/. After inactivation by the pulse application, the shape of the protein shell of SVDV did not change, but RNA contained in the core of SVDV disappeared, and hollow particles were observed. EHV-1 in minimum essential medium (MEM) could also be inactivated effectively when the pulse application number exceeded 45, or the input electrical energy was more than 32.7 cal/cm/sup 3/. Apparent damage to the envelope around EHV-1 and to the core of EHV-1 consisting of DNA could be observed.<<ETX>>","PeriodicalId":185839,"journal":{"name":"Conference Record of the 1990 IEEE Industry Applications Society Annual Meeting","volume":"26 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115770748","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}
