Abstract
To improve the design process of Buck converter, a simplified design method considering minimum switching frequency is proposed. Through theoretical analysis, it can conclude that the minimum capacitance Cmin derived from the output ripple voltage requirement increases as the switching frequency decreases, while the maximum capacitance Cmax derived from the output intrinsically safe performance requirements is independent of the frequency. Therefore, the minimum switching frequency satisfied both electrical index and output intrinsic safety performance requirement. When Cmin equals to Cmax, an expression for the minimum switching frequency fmin is deduced. Then the switching frequency f considering fmin and the expected value range of capacitance is obtained. Based on the minimum switching frequency, a simplified design method of output intrinsic safety Buck converter is proposed. The feasibility and simplicity of the proposed method are demonstrated by the experimental results.
