Abstract
In this paper, a novel adaptive control scheme for interleaved DC/DC power converters is proposed to improve the transient response to load current step inputs with high slew rate. The proposed adaptive control scheme is based upon gain scheduling scheme with pole-zero cancellation method to tune the parameters of the proportional-integral-derivative (PID) controller for efficiently improving the output transient response. The proposed adaptive control scheme is verified on a 12 V input with 1.2 V output, 40 A interleaved DC/DC synchronous buck converter and the simulation and experimental results are presented to fully demonstrate the theoretical analysis.
