Current mode buck converter transfer function
WebA buck converter is a DC/DC power converter which steps down voltage from its input (source) to its output (load). In continuous conduction mode (current through the inductor never falls to zero), the theoretical transfer function of the buck converter is: where is the duty cycle. In this example, the converter is feeding an RC load from a 200 ... WebBased on feedback linearization theory, the sliding surfaces of a SMC in a direct voltage control (DVC) and current control for the buck converters in the PPS are designed, respectively. The feedback linearized SMCs can enforce the system voltage and current to track a desired dynamics on each converter in big signal, which makes the control ...
