State-space model of a class of switched-mode DC-DC power supply

This paper addresses state-space modeling for a class of switched-mode power supplies. The proposed state-space model is composed of multiple dynamics that switch among each other according to pulse width modulation (PWM) signals applied to each transistor and other conditions. The verification test has shown that the model output is very close to that of the actual system and the effectiveness of the proposed modeling approach has been demonstrated.
