Time Domain Digital State-Spase Modeling of PWM Converter

Article presents a method of time-domain digital modeling of PWM converter operating in a continuous conduction mode. Digital values during switching period are introduced with an aim to simplify linearization. It is shown that continuous modeling of variations around steady-state operating point is not a necessary assumption for linearization
