） Abstract： In this paper, a cascade controller is designed and analyzed for a buck converter
The fast inner current loop uses sliding mode control (SMC)
The slow outer voltage loop uses the proportional-integral (PI) control
Stability analysis and selection of PI gains are based on the closed-loop error dynamics
The closed-loop system is proven to have a minimum phase structure
The voltage transients due to step changes of input voltage and load resistance are predictable
The controller is validated by a simulation circuit with non-ideal circuit factors
The simulation results show that the reference output voltage is well tracked under system uncertainties or disturbances, confirming the validity of the proposed controller
