Experimental Study of PWM Based Hysteresis Controller and Amplifier Regulator for a DC/DC Converter

This paper deals with a simulation and practical implementation of a PWM based hysteresis controller for a DC/DC boost converter operating in continuous conduction mode (CCM). Performances and properties of this controller are compared with those of amplifier regulator. Simulation results showed that the hysteresis control scheme provides better performances in the case for set-up DC/DC conversion purposes. Practical results are carried out to show the efficiency of the approach in terms of output voltage regulation and robustness against on line voltage and load disturbances.
