Synchronous Buck Converter

This example shows a synchronous buck converter.

This switched power supply converts a 30V DC supply into a regulated 15V DC supply. The model can be used to size the inductance L and smoothing capacitor C, as well as to design the feedback controller. By selecting between continuous, discrete time, and fixed-point PI controllers, the impact of discretization and using limited numerical precision can be explored.
