Abstract

The analysis and testing of a dc-dc converter by means of the hysteretic control method is presented. In order to design this control method, we used the LM723 integrated circuit, mostly used for the continuous control of the voltage and current sources. Experimental results, as well as simulation results, confirm that the circuit functions well. The proposed circuit represents an alternative for designing dc-dc converter control through the hysteresis method, without using specialized integrated circuits, with low costs and high performances.
