Summary:The invention discloses a large-ripple capacitor voltage numerical calculation method, which comprises the following steps of: discretizing integral terms in a capacitor voltage function relational expression and representing the integral terms in a form of cumulative sums, wherein an original function containing the integral terms of the capacitor voltage function relational expression is implicit, namely, the relational expression is a complex implicit transcendental function equation (1); and subtracting two adjacent points, discretizing an expression to establish a recursive relationship, and performing programming iterative calculation according to a corresponding hypothesis of an integral. The invention respectively provides two algorithms for large ripple voltage of different converters, and provides an effective numerical solution method for a transcendental function which contains an integral term and has an implicit integral original function. 本发明公开了一种大纹波电容电压数值计算方法，包括电容电压函数关系式其含积分项的原函数为隐式，即关系式为复杂的隐式
