14۰ Integrated SRM Drive Battery Charger in Electric Vehicles with Zero Torque Control and Power Factor Correction Date of Submission 2017 03 15 Department of Electrical and Computer Engineering Isfahan University of Technology 84156 83111 Isfahan Iran Supervisor Sayed Morteza Saghaiannezhad Advisor Hamid Reza Karshenas Advisor Jin Woo Ahn Department Graduate Program Coordinator Mohammad Reza Taban Department of Electrical and Computer Engineering Isfahan University of Technology Department of Mechatronics Engineering Kyungsung University Abstract Single Phase and three phase PFC Integrated Battery Charging System using SRM Drive Traction is considered in this thesis In this regard new topology and control is presented For the proposed three phase battery charger position keeping and zero torque PK ZT control of SRM drives is proposed to avoid any movement when used for charging reactor in electric vehicles A sliding mode position control technique as an outer loop and zero torque control method as an inner loop are used to attain this Under any uncertainty dc offset current sensor or giant nonlinearity mutual inductance PK controller is proposed to keep the rotor at the initial position based on simple sliding mode controller Whereas PFC and voltage regulation is achieved with buck boost integrated SRM drive by conventional three phase buck type converter for wide input and output voltage range In this two stage PFC topology multi phase SRM drive operates as a high power interleaved buck boost converter to reduce cost size weight and volume of battery charger with high reliability improved power quality and low battery current ripple Then In order to implement the proposed ZT control an online method is proposed to calculate current reference in each phase with regarding to zero torque condition Finally Lagrange optimization method is used for copper loss minimization during battery charging and results are compared with the case of using an extra clutch to let the motor to move This reliable integrated battery charger topology is cost volume and weight effective while has fast PFC charging capability With proposed method core losses can be reduced significantly because of constant current control and there is no need to clutch during battery charging An online cubic equation method is used to obtain current references with zero torque condition and finally optimized currents are calculated by Lagrange optimization method Results are compared with clutch cubic equation method and Lagrange optimization method Results show that KP ZT keeps the rotor in stand still during charging and zero torque control is not sufficient alone In single phase single stage integrated SRM drive battery charger phase windings and passive components of asymmetric SR converter were used as an interleaved converter with buck mode operation In this circuit just an extra switch per phase was used This topology is easy interconnection because phase windings terminals of SR drive and passive components were used for integrating battery charging The charging converter is based on a buck converter with PFC capability A cubic equation method based on an accurate SRM model is proposed as a current reference distributor of the charging controller with ZT and PFC condition according to the battery pack current demand Results show that PK ZT controller keeps the rotor at stand still while PFC is achieved for battery pack current demand This reliable integrated battery charger topology is cost volume and weight effective compliance with IEC standard To verify the proposed system theoretical analyses of mathematical modeling and computer simulations with MATLAB Simulink have been performed and experimental result is presented based on DSP setup In the end there is a summary of thesis and suggestions for further research Key Words Switched Reluctance Motor Integrated Battery Charger Zero Torque Control Power Factor Correction Position Keeping Control
