Abstract :
A self-tuning pulse-width-modulation (PWM) control is proposed to voltage control for DC/DC buck converter. This paper not only addresses that the DC/DC buck converter with proposed PWM algorithm can attain exactly the desired output voltage but also shows that Lyapunov stability of the closed-loop system is satisfied to various conditions. Use Lead-Acid battery as the load of DC/DC converter with proposed PWM to illustrate the feasibility of regulating desired output voltage.
