Abstract
DC-DC converters with a novel hysteretic PWM controller are presented. A novel feedback network is proposed which behaves as a PID controller. Fast transient response and no steady state error of the output voltage are achieved. Steady state and dynamic analysis are performed and confirmed by experimental results for a 5 V to 1.5 V prototype buck converter. As a result, no steady state error on the output voltage and excellent dynamic performances are derived for the large load current transients. The proposed controller is applicable not only to the buck converter but also to any other types of converters
