Abstract
An error determination module determines a voltage error based on an output voltage of a DC to DC converter, an estimated output voltage of the DC to DC converter, and a product of a predetermined delay value and a difference between a duty cycle and a target voltage. A capacitor current determination module determines a capacitor current based on the voltage error. A capacitor voltage determination module determines a capacitor voltage based on the voltage error. A duty cycle module sets the duty cycle for a sampling period based on the capacitor current and the capacitor voltage. A pulse width modulation (PWM) module controls a switching duty cycle of the DC to DC converter based on the duty cycle.
