For these control modes in light load condition, the zero-current detector (ZCD) to prevent reverse current flowing back to the power source is essential. This paper presents a zero current detection method with enhanced time response of the freewheel switch operation. The proposed ZCD was simulated using a 0.18-μm CMOS process in a test system of PWM voltage mode type-III buck converter, with input voltage of 3.3V. The test system works in CCM at heavy load, PFM at light load, and DCM in a short transient of decision to change from CCM to PFM. The PWM switching frequency is 2MHz, and testing output voltage is 1.8V with load current from 20mA up to 300mA. Under the same test condition, the proposed ZCD shows maximum improvement of 6.9% efficiency in PFM compared to the conventional method, making the overall efficiency greater than 89.7%.","PeriodicalId":377853,"journal":{"name":"2014 IEEE Fifth International Conference on Communications and Electronics (ICCE)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131588797","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}

An example of such UAN consisting of fixed and mobile underwater nodes, was recently developed and tested at sea. A star-shaped network topology was adopted, where wide area network (WAN) integration was ensured through an asymmetric underwater master node composed of an acoustic modem, for low-data-rate downlink from WAN to UAN, and a multiple receiver antenna for single-input-multiple-output (SIMO) high-priority high-data-rate uplink, from UAN to WAN. This paper focuses on the performance of the high-priority SIMO uplink combining multichannel geometry-adapted passive Time Reversal (pTR) and single Decision Feedback Equalizer (DFE) nomenclatureDFEDecision Feedback Equalizer. High data-rate and sustainable communications for mobile and fixed nodes were considered. Two experimental data sets were used: one from the UAN10 sea trial (Pianosa island, Italy, September 2010) for a moving source and UAN11 (Trondheim Fjord area, Norway, May 2011) for a fixed source. BPSK/QPSK signaling, data-rate upto 4000 bps and a source speed upto 0.5 m/s, were considered for carrier frequencies ranging from 5kHz to 25.6kHz. Temporal coherence is shown to be a key factor, determining the performance of pTR-based techniques. Moreover, the geometry-adapted pTR is shown to sustain the temporal coherence in case of geometry changes.","PeriodicalId":377853,"journal":{"name":"2014 IEEE Fifth International Conference on Communications and Electronics (ICCE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132324982","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}
