With the realized driver design it is possible to transfer - galvanically insulated - both energy and information with one single PT. Above all, adapted with resonant driver topologies PTs offer increased efficiencies.enpiezoelectric transformerresonant driverpush-pullamplitude modulatedconventional transformerdriving circuitsenergy and informationhigh-side driverMOSFET switches670620530conference paper
