| Abstract |
The effect of input voltage feedforward (IVFF) on the dynamical performance of a buck converter is investigated. The IVFF scheme is implemented making the pulse-width-modulation (PWM) ramp directly proportional to the input voltage. Ideally the IVFF control would make the internal loop gain constant, perfect attenuation of input noise and resistive input impedance with the phase of 180 deg. The transientresponse of the converter is, however, deteriorated due to limited duty ratio. |
