Abstract
A method of operating a DC-DC converter includes providing a first error signal to a frequency controller, the first error signal derived from a difference between a discontinuous conduction mode input current and a sinusoidal current reference, providing a second error signal to a duty cycle controller, the second error signal derived from a difference between an output signal and an output reference signal, and combining a frequency signal from the frequency controller and a duty cycle signal from the duty cycle controller to produce a complimentary pulse train for driving the DC-DC converter to both control an input power factor and regulate the output signal.
