Reference will now be made to the drawings wherein like reference numerals identify similar structural features or aspects of the subject invention. For purposes of explanation and illustration, and not limitation, a partial view of an exemplary embodiment of a direct current generation system in accordance with the disclosure is shown in FIG. 1 and is designated generally by reference character 100. The methods and systems of the disclosure can be used to decrease the bus voltage ripple, which in turn improves system efficiencies.

FIG. 1 shows a variable frequency generator (VFG) 102 configured to direct alternating current to a first rectifier 104, which is configured to convert alternating current from a generator 110 to direct current and drive it to an HVDC Bus Network 106 responsible for distributing power to various aircraft components. A variable frequency second generator (VFG) 103 is shown including a second generator 111 configured to direct alternating current to a second rectifier 105 configured to convert alternating current from the second generator 111 and also direct it to the HVDC Bus Network 106. The HVDC Bus Network 106 includes a pair of independent DC busses 107/108 configured to distribute power to various parts of the aircraft.
