POWER AND BI DIRECTIONAL DATA INTERFACE ASSEMBLY AND SURGICAL SYSTEM INCLUDING THE SAME

A surgical system includes a power supply, a surgical instrument, and a power and data interface assembly. The power and data interface assembly includes a transformer having a primary winding and a secondary winding, a first modulator coupled to the primary winding and configured to receive a power signal from the power supply, a first demodulator coupled to the secondary winding, a second modulator coupled to the secondary winding, a second demodulator coupled to the primary winding, and at least one capacitor configured to tune the primary winding to a first resonant frequency and tune the secondary winding to a second resonant frequency different than the first resonant frequency.
