Analysis and Design of a Bi-Directional Energy Transfer System using a Rotating Transformer
This paper proposes the design of a contactless energy transfer system with energy feedback mode in case of
large inductance existing in dc supply side, so as to achieve wireless energy exchange between electric vehicle and grid or
home. The design uses a rotating transformer for the power delivery system. Bi-directional flow of energy is due to the
feedback taking place from vehicle battery-power regulator of vehicle side-inverter of vehicle side-resonance circuit-rectifier
of charging machine side-inverter of charging machine side-line connected filter-grid.
