A loosely coupled rotary transformer (100) includes a resonant circuit, such as a resonating capacitor (C3) connected to a power MOS transistor (Q3), coupled across the primary coil (102) of the transformer (100). The resonant circuit is connected and disconnected from the transformer (100) during a power transfer mode and a data transfer mode, respectively. During the power transfer mode, stored energy in the leakage inductance of the primary coil (102) is used for power coupling, via the resonant circuit (C3, Q3), instead of being dissipated as heat. The resonant circuit (C3, Q3) is disconnected from the rotary transformer (100) during the data transfer mode to maximize bandwidth for two-way data transfer between the primary and secondary sides of the transformer (100). Including the resonant circuit (C3, Q3) in the loosely coupled transformer (100) ptimizes data and power transfer without requiring the use of high-cost, high-efficiency magnetic structures in the core of the transformer (100).
