An automated small-signal frequency-domain analyzer for general periodic-operating systems as obtained via time-domain simulation

An accurate small-signal frequency-domain analyzer is constructed and automated through the use of time-domain simulation. Since the algorithm is based on computer time-domain simulation, it can handle arbitrary PWM and resonant-converter topology, any mode of operation, and arbitrary control scheme. The effect of parasitic elements on the small-signal frequency response can also be examined.<
