Abstract Details

2019, Master of Science, Miami University, Computational Science and Engineering.
The main advantages of electric vehicles (EVs) are reducing the production of greenhouse gases, reducing society’s reliance on fossil-fuel-based energy infrastructure, and the ability to achieve high-efficiency energy conversion. Super-capacitors (SCs) are introduced into EV’s energy storage system to supplement the primary power source, which improves the vehicle’s performance. A low-voltage, high-current bidirectional DC/DC converter serves as an intermediary between the SCs and the primary power source connected to the motor drive. Current-fed CLLC converters are characterized by: a lower input current ripple then voltage source converters, extended input voltage range, reduced transformer size, and the ability to achieve soft switching across the entire input voltage range. This research evaluates the performance of a CF-CLLC converter designed with paralleled Si MOSFETs and compares the performance of a CF-CLLC converter, CLLC converter, and cascaded CF-CLLC converter. A hardware prototype was built for an input voltage of 24 V to 96 V and an output voltage of 400 V with a rated power of 2 kW.
