The proposed converter consists of switched capacitors and two coupled inductors. This combination can provide a relatively high voltage boost gain while operating with small duty cycle. The converter can be powered either by one individual DC voltage source in an interleaved manner or two independent DC voltage sources as a multiport converter. The configuration of the proposed converter has advantages such as low power losses, longer lifetime of input sources due to non-pulsating input current, low voltage stress across the main switches and slight output voltage fluctuation. Using this converter, a 22.5 times gain can be reached with 0.6 duty ratio and turns ratio equal to 2 that makes it possible to connect a 20V PV system to a 450V DC bus. Theoretical analysis and simulation results are presented to demonstrate the authenticity of the proposed converter.","PeriodicalId":414828,"journal":{"name":"2017 8th Power Electronics, Drive Systems & Technologies Conference (PEDSTC)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129016386","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 converter can provide bi-directional current and bipolar output voltage with minimal number of elements. In this converter two active switches with complimentary commands and a quasi-Z-source network is required and there is no need to coupled inductors and additional more components. In this paper a reduced order model is proposed to output voltage regulation by means of variable structure control approach. The method employs sliding mode control (SMC) with the converter dynamic model. The proposed SMC approach guarantees stability as well as robustness against input voltage variation, parameters and load resistance uncertainty. In order to demonstrate the capability of the proposed controller, simulation results obtained by PSIM software are presented.","PeriodicalId":414828,"journal":{"name":"2017 8th Power Electronics, Drive Systems & Technologies Conference (PEDSTC)","volume":"777 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116415246","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}

Utilizing back-EMF to estimate the rotor position and speed is one of the few methods that have satisfying performance in low speeds. This method does not require a high speed processor. Capable of controlling the motor over a wide speed range, this method is suitable for hybrid electric vehicles. This method directly controls the wheels and due to its direct performance, it has more efficiency and makes it possible to have a compact circuit. This control method has a relatively quick response to torque variations but the torque ripple is relatively high, which is normal for this method. Moreover, this method is dependent on the machine's internal parameters. Simple implementation and reduced amount of required calculations are the other advantages of the proposed method. The simulation results will verify the proper operation of this algorithm.","PeriodicalId":414828,"journal":{"name":"2017 8th Power Electronics, Drive Systems & Technologies Conference (PEDSTC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115596560","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}

Since bipolar dc microgrids are subjected to severe voltage unbalance, the interlinking converters should be able to perform voltage-balancing function at their dc-link capacitors. In addition, they should exchange power between upper and lower terminals of bipolar dc microgrid. It is shown that the voltage-balancing function can not be integrated into the control system of the NPC converter, so the parallel connection of a voltage balancer is suggested and the pertinent voltage control system is designed. Moreover, a Vienna converter with modified topology and switching algorithm is proposed to perform voltage-balancing function.

Nowadays, even the most promising power converter topologies do not necessarily guarantee optimum performance under all operating conditions. For instance, the efficiency of the power conversion stage may be excellent during periods of high irradiance, but significantly lower in poorer light conditions. In this paper, the energy conversion efficiency of a standalone PV system is maximized over a wider range of operating conditions by employing an interleaved boost converter with novel switch adaptive control scheme.
