A generic algorithm for global steady-state characterization of POL converters

A new algorithm for global steady-state characterization of switching POL (point-of-load) converters as an efficient CAD tool for design and analysis is presented. The global steady-state characterization, involving the conventional simulation of converter operation as well as stress, sensitivity and tolerance analysis, allows for a complex evaluation of converter topology. The presented algorithm is based on efficient evaluation of peaks, ripples, average and rms values of converter internal variables using state variables. The inherent steady-state problem is solved using a new, fast, robust and accurate method for determining converter steady-state. Computer simulation and experimental results are attached.
