Abstract

A nonlinear control buck converter with fast transient response is presented. Methods and principles are analyzed. In the proposed control scheme, the idea of integration is applied and the variable which relates to input voltage and duty ratio is introduced to be compared with the integration variable. The simulations for this design are implemented and simulation results show that fast load and line transient responses can be achieved compared to previously reported techniques.
