This closed-loop scheme is applied to a three-phase squirrel cage induction that drives a mechanical load settled by an induction generator which spins above synchronous velocity. The control goals are to regulate the rotor velocity and the squared module of rotor flux linkages that tracks a signal which varies according to stator currents. The controller design is made in aß coordinate frame where the control input signals are conditioned with space vector pulse width modulation to activate the IGBT's of the three-phase converter bridge. The rotor flux linkages are estimated via a reduced-observer by applying sliding modes; meanwhile, the load torque is estimated by an asymptotic reduced-observer. The robustness of the proposed controller is validated through real-time experimentation under extreme test where the velocity reference signal is a pulse train.","PeriodicalId":260469,"journal":{"name":"2017 IEEE International Autumn Meeting on Power, Electronics and Computing (ROPEC)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129545876","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 contributions of this work are as follows: First, an output buffer driver utilizes a loser-take-all circuit (LTA) and a current mirror amplifier (CMA) circuit to regulate the current in either of the inactive sink or source output driver transistors (FET). In conjunction with the LTA and CMA, a complementary noninverting current mirror (CNICM), monitors and rectifies the sink-source output signals before they are fed to the LTA circuit. Hence, the amplifier's current consumption, attributed to monitoring external loads, is substantially curbed. More importantly, because all the elements of the buffer driver (LTA, CMA, and CNICM) operate mainly in current mode, the output buffer driver is structurally fast and can operate with low VDD of about VGS+2VDS. Second, a floating current source (FCS) function is emulated that can also operate with low VDD and is fast in lieu of utilizing auxiliary common gate amplifiers (CGA). The FCS contains two complementary cascoded FET current sources where the middle cascoded FET's VGSs are held constant and their drain currents are criss-crossed and fed to each other's source terminals, while CGAs regulate the VGSs of the lower FETs, whose currents are substantially equalized and mirrored into the Amplifier's bias network. Montecarlo (MC) and worst case (WC) simulations indicate the following specifications are achievable: VDD minimum ∼ 0.8v; IDD ∼ 200nA; input voltage range rail to rail; output voltage range ∼ 10mV from the rails; open loop gain (AV) ∼ 115dB with unity gain bandwidth (fU) ∼ 600KHz and phase margin (PM) ∼ 30 degrees; power supply rejection ratio (PSRR) ∼ − 88dB; common mode rejection ratio (CMRR) ∼ − 120dB; slew rate (SR) ∼ 2V/ 5uS; settling time (tS) ∼ 10uS; output resistor (RL) capability ∼10K Ohms; and die size rough estimate is 100 um per side.","PeriodicalId":260469,"journal":{"name":"2017 IEEE International Autumn Meeting on Power, Electronics and Computing (ROPEC)","volume":"34 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131116964","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}

A penetration scenario of 10.5%, which corresponds to 31316 vehicles, is considered by allocating electric vehicles to substations. A time domain modelling of an electric vehicle (EV) and an AC Level-2 charger is implemented in a PSS/E-based simulation platform. Furthermore, an uncontrolled charging strategy is implemented in this paper, which is based on the assumption that EVs owners are free to connect and charge their vehicles whenever they want. Power flow solutions are reported in terms of nodal voltages, power losses and loading impacts in the 115 kV sub-transmission system, substation transformers and transmission system. Results show that the load due to the EVs can help to the nodal voltages regulation in the grid during certain times of the day. However, a large number of EVs can significantly increase the losses and exceed the capacity of the transformers depending on the load curve of each substation.","PeriodicalId":260469,"journal":{"name":"2017 IEEE International Autumn Meeting on Power, Electronics and Computing (ROPEC)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127186744","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}
