Abstract :
The averaged duty ratio model for constant on-time control, developed using the conventional modelling technique, shows substantial discrepancies in predicting the large-signal transient behaviour of DC-DC converters. A new technique is proposed for developing an averaged duty ratio model for constant on-time control which overcomes the inaccuracy of the conventional modelling method
