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. The viability of NPC and Vienna converters is evaluated using MATLAB software.","PeriodicalId":414828,"journal":{"name":"2017 8th Power Electronics, Drive Systems & Technologies Conference (PEDSTC)","volume":"27 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":"121810444","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}

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. Experimental result show that the proposed converter control scheme offers better performance and higher conversion efficiency compared to the conventional operation of interleaved converter.","PeriodicalId":414828,"journal":{"name":"2017 8th Power Electronics, Drive Systems & Technologies Conference (PEDSTC)","volume":"60 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":"115068368","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 leakage current of the coupled inductor is recycled by the passive clamp circuit, so the voltage spikes on the power switch are avoided. In addition, the voltage stress on the power switch is reduced. Furthermore, the efficiency of the conversion is increased due to the low switching loss.

The main advantages of the proposed technique are low implementation cost and simplicity of the control strategy. These advantages are achieved through elimination of phase locked loop (PLL) function by the proposed compensation strategy. Phase locked loop functions are considered as an expensive part of a system. Hence, PLL elimination leads to simpler implementation of the power control as well as reduction of the system cost. The proposed power control method is based on modification of normal sliding mode power control using compensation feedbacks for active and reactive powers. Two scenarios including unbalanced angles for three phase voltages and nonidentical voltage amplitudes are considered for unbalanced network conditions. The performance of the modified sliding mode control (SMC) in the mentioned unbalanced conditions is evaluated using simulations in MATLAB/Simulink. The results confirm that the proposed technique reduces the pulsations of active and reactive powers considerably in comparison with the normal SMC strategy.","PeriodicalId":414828,"journal":{"name":"2017 8th Power Electronics, Drive Systems & Technologies Conference (PEDSTC)","volume":"17 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":"133931939","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}

However, in the variable speed drive application, there is a challenge to control the voltage ripple of submodules at the low frequency operating points. This challenge is even more critical during the startup procedure of electrical drives. In this paper, the main reasons of voltage ripple generation are explained. Then a method to control the amount of voltage ripple at the low frequency applications is introduced. In fact, the trapezoidal voltage waveform is injected at the reference of phase voltage to reduce the voltage ripple. Next, the proposed method is compared with existing methods to show its better performance.
