Abstract:
The main objectives of the thesis are:
• To present an overview of the automobile electrification trends.
• To find an algorithm for battery internal resistance estimation.
• To introduce a novel, on-line battery state-of-charge algorithm for valveregulated lead-acid batteries.
• To develop a simulation model for the complete BEGA control system including the three-phase PWM inverter and dc-dc excitation converter
• To implement a vector control strategy for BEGA.
• To prove that BEGA has a very large constant power speed range at unity power factor operation.
• To find a minimization strategy of the copper losses in BEGA.
• To find a strategy for improvement of BEGA electromagnetic torque response
• To develop a sensorless control strategy for BEGA operation in a wide speed range.
