    Abstract: This dissertation proposes a novel bidirectional full-bridge CLLC converter
    that is suitable for electric vehicle applications in the power grid system. The
    converter has bidirectional energy transfer capabilities, allowing for energy to be
    transferred from the high-voltage side to the low-voltage side and vice versa. In
    both modes, all switches exhibit soft-switching characteristics, which effectively
    reduce switching losses on both the high-voltage and low-voltage side power
    switches. Additionally, this converter has distinct resonant frequencies that extend
    the load range for zero-voltage switching (ZVS) and zero-current switching (ZCS),
    thereby enabling the converter to achieve improved efficiency under light-to-halfload conditions. This dissertation implements a prototype of a 2 kW-rated power
    converter that utilizes the Texas Instruments digital signal processor
    TMS320F28335 as the control platform. With its fast computation capability and
    flexible control planning, the converter achieves bidirectional energy transfer
    between high and low voltages. Through experiments, it has been verified that the
    efficiency is significantly improved under light-to-half-load conditions.
