Electricity generation using Photovoltaic cells is a promising form of sustainable energy. A quasi-Z source inverter (q-ZSI) can minimize the power fluctuations from the electric energy generated by a PV panel. In the existing system, during the discharge of energy stored battery Harmonic Distortion is more. The proposed topology describes an improved ability to compensate power while maintaining a constant dc-link peak voltage with minimum harmonics. It is promising to note that the THD level decreases significantly with the introduction of a closed loop controller with Selective Harmonic Elimination technique. Thus the proposed system provides an efficient means of PV power generation.","PeriodicalId":71630,"journal":{"name":"新能源","volume":"1 1","pages":"143-147"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89657785","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 high voltage gain converter which is used to step-up the voltage has many applications, like fuel cells and discharge lamps. To step down the output voltage a half circuit is used which produces half of the input voltage. The step down converter is used for applications where high efficiency is required, this converter is also of low cost and has power saving capacity. In this paper, the high voltage gain step-up converter is a single switch converter which is nonisolated type dc-dc converter to combine coupled inductor and voltage doubler cell with diode capacitor techniques. Very large voltage conversion ratio with proper duty cycle is achieved by this step-up converter and this converter also reduces stress on the switch. The efficiency is increased by effectively recycling the leakage energy stored in the coupled inductor. The high pulsed input current problem is eliminated by the use of coupled inductor. This new converter is small in size and has very large conversion ratio with high efficiency for industrial applications.","PeriodicalId":71630,"journal":{"name":"新能源","volume":"39 1","pages":"135-139"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81144065","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 SVPWM is voltage orientated control producing pulses for the converter switches. The vector modulation of the pulse generation reduces the losses and the harmonics due to the inductive nature of the load. The system is designed to extend its application to the wind energy conversion system (WECS) using a fixed speed wind turbine, which is mathematically, modeled using the machine equations of the self-excited induction generator (SEIG).

This comb drive capacitive pressure sensor isolates the pressure sensing diaphragm from its capacitance sensing movable comb plate by a mechanical coupling so that it increases the pressure sensitivity. The design and simulation of the sensor is analysed using Comsol Multiphysics 4.4. The stress distribution of the membrane and capacitive sensitivity analysis is carried out for the range of pressure from 0 to 10 bar. The dimension of the Capacitor plate with comb is 200μm ×200μm ×3 μm. The sensor works efficiently in the range of 30°C to 270°C.

Corresponding to the conventional power system ac microgrid have been proposed, particularly increasing the use of renewable enery sources generate dc power which need a dc link for the grid connection and as a result of increasing modern dc loads. Dc microgrid have been recently emerged for their benifits in terms of efficiency cost and no of conversion stages. The ac microgrid are dominant in power system, but it doesn't replaced by the dc microgrid, so we are interfacing ac and dc microgrid by interlinking converter(IC) for proper power management and decentralized control, which exploiting the prominent features of both ac and dc microgrid. During the islanding operation of the hybrid ac/dc microgrid, the IC is intended to take the role of supplier to one microgrid and at the sametime acts as a load to the other microgrid and the power management system should be able to share the power demand between the exiting ac and dc sources in both the microgrids. This paper considers the power flow control and management issues amongst multiple sources distributed throughout both ac and dc microgrids.
