In this paper we discuss the use of the feeder cable itself for communication instead of the extra cable by using the well known technology in domestic applications, the PLC \"Power Line communication\". However, the feeder cable is not designed for data transmission for being a noisy environment. Therefore, PLC modems developed for domestic applications may not be suitable. The aim of our study is to highlight limitations and difficulties that obstruct transmission in industry. Also, we underline the use of a PWM filter and a coupling interface with specific characteristics in order to overcome those limitations.","PeriodicalId":200366,"journal":{"name":"2009 Twenty-Fourth Annual IEEE Applied Power Electronics Conference and Exposition","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132849556","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}

Due to the ripples of DC voltage and dead time effect, an un-neglected predict error of state observer will presents. To overcome the predict error, a repetitive compensator is added to the state observer, and its nice performance is proved by both simulations and experiments.

A state machine sets the peak current of enabled cycles, based on the load requirements. At light loads, the variable frequency nature of this control scheme reduces switching losses significantly, while the lowering of the peak current by the state machine reduces the output ripple and audible excitations of the transformer. The state machine control is completely modeled for the first time, including new modeling for the peak-current ratio between DCM states, the number of DCM states required for stability, the minimum number of counts for DCM state transitions required for stability, and DCM modeling for a new peak state with double the maximum switching frequency, which provides peak power during brief peak loads, without requiring an over-rated transformer [1-3]. Characterization of a supply that was designed around the monolithic IC that uses this control scheme is provided.","PeriodicalId":200366,"journal":{"name":"2009 Twenty-Fourth Annual IEEE Applied Power Electronics Conference and Exposition","volume":"42 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134259001","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 controller operates as a mixed-signal peak current program mode voltage regulator, where a digital current reference is created and used for the efficiency optimization. The losses of the power stage are minimized by combining power stage segmentation and gate swing variation. Based on the current reference, in each switching cycle, the optimal number of power switch segments and gate drive voltages are set through a sequence controller and a novel dual-output switch-capacitor circuit. The effectiveness of the system is verified on a 1.8 V, 5 W, 1 MHz buck converter prototype.

And, a phase locked loop is included in the DPWM providing wide-frequency range signal synchronization as well as process, voltage and temperature (PVT) insensitivity facilitating accurate switching frequency control. Taking low cost two metal layers 0.6¿m AMI06 process and 9-bits resolution bit requirement as an example, a 8MHz switching frequency DPWM is designed and implemented in 0.703mm2 die via MOSIS educational program.
