1. A power delivery system, comprising:

  • a rotary transformer comprising a primary winding and a secondary winding, wherein;

    the rotary transformer is configured to deliver first power to a high voltage component and second power to a lower voltage component concurrently, andthe secondary winding is configured to produce a modulated signal comprising at least a modulated amplitude and a modulated frequency; and

    an auxiliary component disposed on a first circuit through which the second power is delivered via the modulated signal from the secondary winding to the lower voltage component, wherein;

    the auxiliary component comprises a rectifier, andthe auxiliary component is configured to adjust a first voltage applied to the lower voltage component based at least in part upon the modulated amplitude of the modulated signal.
