1. A method of operating a voltage bus system, comprising: providing a voltage converter having one or more subcircuits comprising: a power supply input, an output DC voltage bus, a power factor correction circuit, a bidirectional isolation circuit, a controller configured to receive a positive output feedback signal, said controller comprising: a multiplier configured to multiply a first voltage feedback signal by a difference between a second voltage feedback signal and a voltage reference, wherein said multiplier produces a multiplier output; a first analog inverter configured to invert said multiplier output; a second analog inverter configured to invert a current feedback signal; a differential amplifier configured to amplify a difference between said first analog inverter output and said second analog inverter output; a pulse width modulation generator configured to generate a pulse width modulated signal as a function of said differential amplifier output; a third inverter configured to invert said pulse width modulated signal; and a command, wherein said controller is configured to provide said power factor correction circuit and said bidirectional isolation circuit with pulse width modulated signals; causing said voltage converter to provide a DC voltage at a first voltage level on said output DC voltage bus; receiving a target voltage change command; and dynamically adjusting said voltage converter to cause said voltage converter to provide a DC voltage at a second voltage level on said output DC voltage bus in real-time, wherein said voltage converter is operable to dynamically adjust said DC voltage to said output DC voltage bus above or below said power supply input.
