Abstract :
A new iterative technique for steady-state analysis of PWM DC/DC switching regulators is presented. The algorithm consists of two iteration loops. The first one is to iterate the steady-state network waveforms at a presumed duty cycle while the second one is to iterate the steady-state duty cycle of the pulse-width modulator output. The circuit waveforms are obtained by a stepwise time domain simulation method, which is based on using stepwise quadratic formulations of the circuit stale variables with progressive analysis of switches´ state. An example of PWM boost regulator is used to illustrate the computational efficiency and accuracy
