In the proposed approach, only six switches of the typical SPMC topology are used to convert the voltage 240 Vrms (50Hz) input to a 12 VDC DC link. In the proposed topology a current control loop is used to ensure that the supply current waveform is continuous, sinusoidal and in-phase with the supply voltage resulting in high input power factor with low total harmonic distortion (THD) level. Therefore, the input currents are of a high quality and devoid of low frequency harmonics under varying load conditions, inherently. Simulation results verify the feasibility of the proposed converter.","PeriodicalId":110449,"journal":{"name":"2011 IEEE Symposium on Industrial Electronics and Applications","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125985379","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 digital design flow is typically top-down, thus allowing a continuous verification of the matching between specification and simulation results. Instead the analog flow is more frequently bottom-up and this makes hard to feedback information from the bottom level simulations to the design top level, being almost impossible SPICE simulations of the whole system (due to the excessive simulation time, convergence troubles and computational effort). This kind of mixed-signal separated flow can easily lead to a final assembly which is not sufficiently tested (such strategy cannot provide the designer with much confidence that digital and analog portions will interface correctly) and thus it's extremely difficult to debug. A full covering test strategy is not allowed also for another reason: many tests are not possible at HDL level, because of the lack of interactivity during simulation process. In fact, if we consider for example a generic calibration sequence, the procedure must assign parameter values depending on DUT state, by changing actions to perform, relating to effects of the previous acted. In this paper we propose a complete environment to test together analog and digital parts by using a semi-automatic VHDL-AMS flow adding the use of Python scripts to drive the simulation, interacting with both Verilog top-level model or real chip, creating a dynamic co-operation for real-time data processing with high re-usability for a fast conditional complete test flow.","PeriodicalId":110449,"journal":{"name":"2011 IEEE Symposium on Industrial Electronics and Applications","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117087768","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 modern signal integrity flows, a very high level of pessimism is incorporated into the noise methodology to augment the lack of accuracy, such as lumped aggression, noise ramps and lumped slews. Desirably, such pessimistic assumptions are much easier to compute hence efficient on simulation runtime, but often than ever it will result in an overdesigned chip. This paper discusses a recipe to reduce pessimism in interconnect noise methodologies by effectively modeling the downstream degradation on the aggression line. We will be presenting an aggression slew estimation method derived from the Elmore delay, which has less than 0.8% error compared to SPICE simulations and is inclined towards the higher slew bound when compared to both Elmore's delay and SPICE. We also show that the dAP method reduces the average reported noise by 5% even when we account for victim-aggressor reverse aggression issues.","PeriodicalId":110449,"journal":{"name":"2011 IEEE Symposium on Industrial Electronics and Applications","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130914013","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 so-called figure-of-merit, which is defined as the product of the specific on-resistance (Ron.sp) and Qgd is commonly used to quantify the switching performance for a specified off-state breakdown voltage (BVds). Two approaches are taken to reduce the Ron.sp & Qgd. First is by shrinking the trench gate width to increase the cell densities up to 645Mcell/inch2 for an ultra low on state resistance using 0.18um design rule process. The other is to obtain lower Qgd with thick bottom oxide (TBO) at minimum trench gate width by double HDP processing.

This incremental placement serves as a post-placement optimization solution that provide a cells position adjustment strategy such that no cells overlap occur and ensure no significant deviation from initial placement.

The effect of transient occurrence can lead to malfunction of electronic control equipment. Transient analysis can be conducted using simulation software package. One of the commercial simulation software package that used by industry worldwide is Siemens Power System Simulation for Engineering (PSS/E). This research paper highlights the usage of PSS/E to analyze Sarawak's Grid System stability using the simplest dynamic model that has been embedded into the program. To observe transient analysis using PSS/E, basic machine model such as generator, exciter and governor were used by varying default data in the program to find the best simulation output. This paper also analyzed the theory of critical clearing time (CCT) of fault occurrence between a transmission line near to the generator and far from the generator. CCT appears to be lesser when the fault occurs at a transmission line near to the generator. On the contrary, when fault occurs far from the generator, the duration of CCT is greater. The stability of the system is observed based on the machine rotor angle, machine speed, output electrical power and terminal voltage.","PeriodicalId":110449,"journal":{"name":"2011 IEEE Symposium on Industrial Electronics and Applications","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130758223","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}
