Abstract
The output voltage of DC-DC converter contains the ripple and it substantially affects the frequency response although the ripple is usually neglected in the control circuit as PWM control. The authors already have clarified that the effect of the ripple is not ignorable for the frequency response and it causes the unusual characteristics. In this paper, we analyze the effect of the ripple in consideration of ESR of the output capacitor of the boost converter. As a result it has been found that the effect of ESR in the stability is different according to the shape of the slope direction of the ramp generator in the PWM circuit.
