摘要：
This paper describes a simple-yet-effective control method for a DC-DC buck converter with voltage mode control (VMC). We propose to use a slope adjustable triangular wave generator (TWG) which provides a line feed-forward control and an additional duty cycle modulation effect. Then comparing with the conventional VMC, the proposed method significantly improves the line and load transient responses. This triangular wave slope regulation scheme is simple compared to digital feed-forward control scheme that requires non-linear calculation. Our SIMetrix Simulation results show the effectiveness of the proposed method.
