Abstract :
A new PSpice-based model is developed for simulating the soft-start characteristics of switching power supplies. Three commonly-used control ICs: TL494; SG3525; and UC3825 are considered. Using this model, starting characteristics of power supply circuits can be simulated effectively even with popular personal computers
