SPICE modeling and simulation of hysteretic current-controlled Cuk converter

摘要

Based on techniques proposed for the modeling of PWM (pulse width modulation) controlled converters, low frequency behavior models of hysteretic current-mode controlled Cuk power converters, including ones with coupled inductors, are developed. These models are simple, accurate, and easy to use. Computer simulations based on such models are carried out for the analysis of the delta V/sub o// delta V/sub i/ and delta V/sub o// delta I/sub C/ transfer characteristics and transient responses. The simulations are verified by experimental measurements.
