The PV panel/array is connected with the converters with the MPPT techniques (P&O algorithm) which extracts the maximum power from the PV. The converter performs the buck or boost operation depending on the requirement and the output voltage from these converters are given to the Voltage Source Inverter (VSI) of the rated voltage 415V. The inverter converts the DC voltage to its equivalent AC voltage and AC voltage of 415V is given as the input to the three-phase Induction Motor (Three-phase IM) which further drives the centrifugal pump. Here, three converters namely SEPIC, Zeta, Landsman converters are used and their performances are investigated. Also the comparative study of the three converters is done and the results of various parameters obtained at the output of the three converters along with the output parameters of the motor and centrifugal pump. The simulation and execution of these three PV based pumping application systems are done in the MATLAB/Simulink environment. The results obtained from the comparative study helps us to select the best suited system for the pumping application.","PeriodicalId":275077,"journal":{"name":"2017 IEEE Conference on Energy Conversion (CENCON)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129495191","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}

This paper concentrates on a ramp comparison method which mainly focus on pulse width modulation (PWM). In PWM, the reference with compensated error is compared to a triangle waveform. The desired reference current from the inverter is produced through the generated reference signal. Nevertheless, the conventional method becomes complex in determining the reference signal if the system's ac main voltage varied. Thus, this paper proposes a simplified equation of the reference signal in order to cut down the mathematical complexity. The simplified method is verified using a 5 kVA single phase half-bridge grid-tied inverter. The simulated result shows the difference of the error uncertainty for the desired reference current between conventional and simplified equations is ±0.02 %.","PeriodicalId":275077,"journal":{"name":"2017 IEEE Conference on Energy Conversion (CENCON)","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128532258","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}

In addition, the output of the battery model is observed in Simulink. After that, the critically damped state-space design method by using state feedback method is discussed and implemented in Simulink. The battery model is implemented in Simulink using DC machine for charge and discharge and two ways of SOC estimation discuss with implementation in Simulink.

Moreover, the utilizing of the magnetizing inductance and the phase shifted angle ensures the achievement of the ZVS for all switches. The proposed converter was simulated using MATLAB-Simulink software. It was found that the variable frequency control is suitable for LLC resonant converters in terms of obtaining wide load variation.

The aim is to reduce the chattering effect that arises when utilizing conventional sliding mode controllers (SMC). This is achieved by introducing the adaptation laws that allow the controllers gains to be self-tuned towards their optimum values. Furthermore, the discontinuous signum function is replaced by continuous functions in the controller structure. To verify the proposed control scheme, a grid-connected PV system which comprises of a 4.6 kW PV generator, a dc/dc boost converter, a three-level NPC voltage source inverter (VSI) and an R-L filter is considered for simulation using Matlab/Simulink. The ac-side control unit includes: an outer dc bus voltage controller, an inner grid current controller and a phase angle estimator. The simulation results shows that total harmonic distortion (THD) of the grid current is reduced by 28%, while the steady state error using the ASMC-based phase angle estimator is practically brought down to zero.","PeriodicalId":275077,"journal":{"name":"2017 IEEE Conference on Energy Conversion (CENCON)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134035039","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 performance of CFTC depends mainly on the torque loop bandwidth; the higher the bandwidth, the better the performance of CFTC-DTC drive. This paper proposes a modification on the frequency carriers of CFTC to increase the torque loop bandwidth. Unlike the conventional CFTC, the carriers of proposed CFTC are generated by ramp waveforms resulting in 50 % increase of the carrier frequency.
