In this scenario, one can highlight the necessity of high power density rectifiers for reducing current harmonics and providing a stabilized intermediate dc-link for connection of electronic loads. Therefore, in this paper the authors present the analysis concerning the development of a novel proposal of hybrids rectifiers structures with wide range of DC voltage regulation based on Series DC Voltage Compensation Technique (SDCVC). The proposed SDCVC Technique provides voltage sag-ride through capability and assures high power density and high efficiency. In order to validated the effectiveness of the proposed solutions, preliminary modeling analysis was performed and corroborated by experimental results obtained through a 1 kW laboratory prototype of a single-phase hybrid rectifier that was put into operation under normal AC system operation, as well as under conditions of AC voltage dips.","PeriodicalId":256756,"journal":{"name":"2013 Twenty-Eighth Annual IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":"2014 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127466499","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}

Two configurable power supply schemes are explored for the voltage doubler in vibrational energy harvesting applications. An `input-powered' power supply scheme eliminates standby power consumption of the circuit when the harvester is not active. Alternatively, a `cross-connected' power supply scheme reduces the minimum input voltage without additional circuit cost. Implemented in On Semi 3M-2P 0.5 μm CMOS technology, the circuit is first benchtop characterized with a signal generator and then also demonstrated with a vibrational energy harvester. A maximum power efficiency of 87% is achieved using the input-powered scheme for a 1.5 V ac input amplitude and 960 μW of output power. In the cross-connected scheme, the circuit is able to rectify input voltage amplitudes as low as 400 mV, below the transistor threshold voltage of 700 mV.","PeriodicalId":256756,"journal":{"name":"2013 Twenty-Eighth Annual IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132035706","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}

Most of the modern solutions of eliminating load current harmonics by using active filter is based on sinusoidal source voltage. However, the voltage at PCC is not purely sinusoisdal. This paper proposes a shunt active filter (SAF) based on instantaneous active and reactive power theory which can mitigate the load harmonics properly even if the source voltage is distorted. Space vector PWM based voltage source inverter is used in current control mode to filter out current harmonics. PI controllers are used for the current controller to get desired dynamic response.

To continue to scale digital throughput at constant power density, there is a need for increasing parallelism and dynamic voltage/bias scaling. This work presents an architecture and power converter implementation providing efficient power-delivery for microprocessors and other high-performance digital circuits stacked in vertical voltage domains. A multi-level DC-DC converter interfaces between a fixed DC voltage and multiple 0.7 V to 1.4 V voltage domains stacked in series. The converter implements dynamic voltage scaling (DVS) with multi-objective digital control implemented in an on-board (embedded) digital control system. We present measured results demonstrating functional multi-core DVS and performance with moderate load current steps. The converter demonstrates the use of a two-phase interleaved powertrain with coupled inductors to achieve voltage and current ripple reduction for the stacked ladder-converter architecture.","PeriodicalId":256756,"journal":{"name":"2013 Twenty-Eighth Annual IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126572915","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}

Furthermore, modern power converter guarantee high power quality, high conversion efficiency levels, reliability and flexibility. This work reviews and compares two types of modulation schemes to two novel ones that are able to drive a Δ-switch rectifier. The presented theoretical analysis is based on a WECS application.
