Abstract :
A new control method for boost and buck-boost converters employing a hysteretic PWM controller is presented. The triangular voltage obtained from a simple RC network connected to an auxiliary winding of the inductor is superimposed to the output voltage and fed to a hysteretic comparator as a feedback signal. The presented control method provides no steady-state error voltage on the output and excellent dynamic performances for the variations of the input voltage and the load current
