Current-mode control, five different types, used with the three basic classes of power converters: Small-signal AC and large-signal DC characterization, stability requirements, and implementation of practical circuits

摘要: Current-mode control effectively eliminates the phase lag of function, associated with output filter inductor or energy-storage inductor. The several types current-mode controllers differ slightly in their phase-lag characteristics, but they are all far superior to commonly used PWM duty-ratio controllers. Unfortunately, industry has been slow appreciate and exploit considerable advantages control. There seem be two reasons for that: (a) unavailability integrated circuits which well-suited implementing (b) lack detailed, systematically organized, theoretical practical information on objective this paper is fill gap by providing a well-organized compendium useful design engineer who wants understand operation current-mode-controlled power converter accomplish an optimal design. Five different methods considered, three basic regulated rectangular-wave converters.
