Second-order sliding-mode controller for higher-order DC-DC converters

The paper adapts the second-order sliding mode (SOSM) control technique to higher-order dc-dc converters. In particular, the paper presents an adaptation of this control technique for buck converters with input filter. The approach consists of regulating the converter output voltage by means of a state-machine similar to the basic SOSM controller, which is shown to perform well as long as the input filter is properly damped, thus ensuring the overall converter stability. Stability and fast dynamic responses are verified by simulations on a 5 V-to-1.3 V point-of-load buck converter with a damped LC input filter.
