Abstract :
A novel PWM control method with constant switching frequency for DC-DC converters is proposed. The proposed control method has excellent control characteristics and is suitable for the low-voltage high-current dc-dc converter which requires a fast transient response. The transfer function of the proposed controller is obtained by small signal ac analysis, and the dynamic characteristics of the regulator are examined by simulation and experiments. The results show the proposed method provides excellent dynamic performance and stable switching action without using an error amplifier in the controller.
